Transitions
Trouble with Change
Chapter 9 — At a Glance
Wednesday glared up at Zak from his color-coded planner. The bright yellow highlighter pierced his eyes like a warning signal. Yellow meant worksheets—predictable, orderly worksheets that made the chaos of high school manageable. His fingers traced the familiar routine he’d written out the night before: sharpened pencils, three blue pens in case two failed, his lucky eraser positioned at the top right corner of his desk. The mental checklist calmed his racing thoughts.
The hallway to Mrs. Jordan’s astronomy class felt overwhelming today. Fluorescent lights buzzed overhead like angry wasps, their harsh glare reflecting off the freshly waxed floors in dizzying patterns. His stomach tightened as he shuffled into the classroom. Something felt different. Mrs. Jordan’s usual calm smile seemed too bright, almost electric.
But as soon as the class settled, what he had constructed in his mind shattered like a dropped mirror.
“Alright, class,” Mrs. Jordan announced, “Surprise! Today, we’re ditching the worksheets and taking a field trip to the planetarium!”
The room erupted in excitement. Chaos crashed over Zak like a tsunami. The word ‘Surprise’ echoed in his head like a warning bell. His chest tightened, each breath becoming shorter and more painful. The familiar frustration bubbled up — a hot, prickly feeling that started in his chest and spread like wildfire through his limbs. Before he could stop himself, he slammed his hands down on his desk, scattering everything across the floor.
Dead silence. Twenty-four pairs of eyes stared at him. Heat crawled up his neck as the day crumbled. Mrs. Jordan, however, held up a hand, silencing the whispers that had begun to ripple through the room. Her voice carried a note of understanding that slowed Zak’s racing heart just a fraction…
Think of transitions as your brain shifting gears, similar to a transmission. For most people, shifting between activities or phases of life happens smoothly — like a well-oiled machine. But for our neurodiverse children, these shifts require their brains to work much harder, using multiple systems simultaneously.
Transitions aren’t just about moving from one activity to another — they’re complex neurological processes that involve:
- Disengaging from the current activity (releasing the old gear)
- Processing and accepting the change (finding the new gear)
- Adapting to new demands (engaging the new gear)
- Managing the emotions that come with change (smoothing out the shift)
For our neurodiverse children, this process is particularly challenging because their brains process sensory information differently, take longer to shift between tasks, require more energy for executive functioning, and may experience heightened emotional responses to change.
The research on transitions reveals challenges that are both significant and deeply underappreciated in schools and homes.
- Transitions can consume up to 32.4% of valuable instructional time in schools.2 For our children, this percentage can be even higher due to how their brains process transitions.
- When children anticipate changes, their brain has time to prepare — reducing anxiety and resistance. Research shows advance notice can reduce transition-related behaviors by up to 60%.9
- Consistent routines create neural pathways that make transitions more automatic and less stressful over time — the brain can actually build more efficient transition circuits through repetition.10
- For children with FASD, trauma, and ASD, a single unexpected schedule change can trigger a survival response that requires hours — not minutes — to recover from.
- Rituals and routine-checking behaviors are often not defiance — they are a coping mechanism to manage anxiety. Understanding this changes everything about how we respond.1
A transition that takes a neurotypical person 30 seconds may require 15–30 minutes of mental and emotional preparation for a neurodiverse child. This is not stubbornness — this is neurology.
The book covers three key symptom categories. This page gives you the full picture — ten comprehensive categories of transition-related symptoms commonly observed across ASD, ADHD, FASD, and trauma. These symptoms are frequently mistaken for defiance, manipulation, or lack of effort. Understanding them for what they are changes everything about how you respond.
Click each category to expand.
These reactions stem from the brain perceiving change as a threat, triggering survival responses. This is not defiance — it is an automatic reaction to perceived danger.
- Meltdowns, tantrums, or shutdowns when asked to transition
- Excessive anxiety or distress before a known transition (e.g., school drop-off)
- Rigid adherence to routines, struggling when things don’t go as planned
- Irritability, frustration, or defiance in response to unexpected changes
- Heightened stress levels when anticipating upcoming transitions
- Stalling or procrastination (“Just five more minutes!” repeatedly)
- Ignoring instructions to transition to a new task
- Pretending not to hear or refusing to acknowledge it’s time to switch
- Hiding, running away, or engaging in distractions to delay transition
- Sudden fatigue or complaints of physical symptoms (“I’m too tired” or “I feel sick”)
Note: Physical complaints before transitions are often real — the stress response genuinely produces physical symptoms like stomach aches, headaches, and nausea.2 These are not fabrications.
- Fixation on routine, reacting negatively to even minor changes
- Inability to switch between tasks smoothly (e.g., stopping a video game to do homework)
- Excessive questioning (“Why do I have to?” “Why can’t I do it later?”)
- Needing extra time to mentally process that a transition is happening
- Arguing over fairness or reasons for change (“That’s not how we usually do it!”)
These behaviors often look like willful defiance, but they are typically an external expression of internal overwhelm.
- Yelling, complaining, or arguing instead of transitioning
- Throwing objects or slamming doors when asked to move on
- Refusing to comply or pretending they didn’t hear directions
- Insisting on finishing a task completely before moving on, even if unnecessary
- Blaming others for the transition (“You’re making me stop for no reason!”)
Task Completion Anxiety is a real neurological experience — not stubbornness. The fear of leaving something unfinished can feel visceral and unbearable.
- Becomes stuck or frozen, unable to take the next step
- Stares blankly or zones out, needing extra prompts to transition
- Repeating the same question about what’s next, even after multiple explanations
- Disorganized and forgetful during transitions (e.g., leaving items behind)
- Appears confused or disoriented when the transition starts
- Intense fear of losing progress or leaving something unfinished — leading to resistance, anxiety, or emotional outbursts5
Transitions often introduce additional sensory input — noise, movement, visual stimuli — which can overload processing capacity on top of the transition demand itself.
- Pacing, fidgeting, or excessive movement before or during a transition
- Clenching fists, grinding teeth, or showing signs of physical tension
- Covering ears or avoiding eye contact to self-regulate during transitions
- Fidgeting with objects or engaging in self-soothing behaviors (rocking, nail biting, tapping)
- Sensory meltdowns triggered by environment changes (e.g., bright lights, new smells, crowded hallways)
The mental energy required to navigate transitions can make social interactions feel like an additional burden — leading to withdrawal and reduced communication.6
- Difficulty shifting conversations (wants to continue talking about their preferred topic)
- Needs constant reminders and reassurance about what’s next
- Asking repetitive questions (“What are we doing now? Are you sure?”)
- Struggles with processing verbal directions — needs visual or hands-on guidance
- Withdrawing, isolating, or becoming less communicative during times of change
- Overly reliant on adults to guide them through every transition step
Reduce social pressure during periods of transition. This isn’t the moment for complex conversations, high expectations, or behavioral corrections — this is the moment for presence and predictability.
- Excessive distress over big changes (e.g., moving, switching schools, new teachers)
- Difficulty adjusting to new rules and expectations
- Regression to younger behaviors (e.g., clinginess, baby talk) during big transitions
- Heightened anxiety about the unknown, needing repetitive reassurance
- Withdrawing socially or acting out in response to change
Big transitions require big preparation. For major life changes like moving, changing schools, or graduating, begin preparing your child weeks or months in advance. Preview the new environment. Meet new people before the day. Create visual stories about what the change will look like.
Time blindness is not a choice — it reflects how their brain processes the passage of time. Traditional time warnings like “5 more minutes” may not register meaningfully.3
- Loses track of time, struggling to pace activities
- Forgets upcoming transitions and is genuinely caught off guard
- Difficulty shifting gears quickly, needing long warnings
- Struggles with estimating how long things take
- Becomes deeply engrossed in tasks, genuinely surprised when it’s time to leave
- Overly focused on the past activity, unable to move forward mentally
Common in teens with attachment issues, PTSD, or early childhood trauma. Transitions can activate memories of past instability, loss, or danger.
- Hypervigilance before transitions — scanning for danger or control
- Emotional flashbacks tied to past instability (e.g., fear of abandonment)
- Extreme startle response when the transition is abrupt
- Freezing or dissociation instead of responding to transition cues
- Intense fear of the unknown, assuming worst-case scenarios

How This Can Impact Daily Life
School changes — making mornings and class switches consistently hard, leading to frequent tardiness and dysregulation
Resistance to new experiences — leading to avoidance behaviors and missed opportunities
Frequent power struggles with parents and teachers who misread the behavior as defiance
High dependence on routines — making family flexibility, vacations, and schedule changes extremely difficult
Long-term adjustment difficulties — including moving, changing schools, new siblings, relationship changes
Emotional exhaustion for both child and parent — when every day contains multiple unmanaged transitions
Use this matrix to identify which support strategies are most effective for different types of transitions. Combining multiple approaches consistently works best — what works one day may not work the next, so stay flexible and keep the relationship central.
| Type of Transition | Prepare in Advance | Create Routine | Breathing & Redirecting | Offer Choices |
|---|---|---|---|---|
| Daily Routines | ● Most Effective | ● Most Effective | ● Most Effective | ● Most Effective |
| Activity Changes | ● Most Effective | ● Mod. Effective | ● Most Effective | ● Most Effective |
| Environmental Shifts | ● Most Effective | ● Mod. Effective | ● Most Effective | ● Mod. Effective |
| Social Transitions | ● Mod. Effective | ● Most Effective | ● Most Effective | ● Most Effective |
| Schedule Changes | ● Most Effective | ● Mod. Effective | ● Mod. Effective | ● Most Effective |
| Life Changes | ● Most Effective | ● Most Effective | ● Most Effective | ● Most Effective |
● Most Effective = Works well for most neurodiverse children | ● Moderately Effective = May be helpful depending on needs
Key Takeaways: Identify patterns — observe how your child reacts to different transitions. Mix and match strategies — combining multiple approaches consistently works best. Create emotional safety — connection before correction helps reduce stress. Stay flexible — what works one day may not work the next; adjust as needed.
Think of your role as an air traffic controller managing multiple flights. We’re not trying to force sudden changes — we’re creating clear pathways and safe landing zones for our children to navigate from one activity to another. The goal isn’t to eliminate the turbulence of transitions entirely but to provide the tools, guidance, and support that help our children move through changes with greater confidence and less stress.
Prepare in Advance
Mental GPSWhen children anticipate changes, their brain has time to prepare, reducing anxiety and resistance. Research shows advance notice can reduce transition-related behaviors by up to 60%.9 Think of this like giving your child a “mental GPS” — they need directions and time to prepare for the next destination.
- Create picture schedules showing daily sequences with images representing each activity
- Use timers or time visualizers — many children respond better to visual time (sand timers, Time Timer clocks) than verbal warnings
- Make transition charts for regular routines and post them where your child can see them
- Practical tip: Consider using an old smartphone as a dedicated visual schedule device. Set alarms with your child’s favorite songs for different transitions.
- Give multiple warnings — 15 minutes, 10 minutes, 5 minutes, then 2 minutes
- Use consistent transition phrases so the language itself becomes a predictable signal
- Explain changes in simple and concrete terms — what’s ending, what’s coming, and what will stay the same
- Role-play new transitions before they happen — preview the new environment, the new schedule, or the new people
- Create social stories about what changes can look like, including what your child can do if they feel overwhelmed
- Practice coping strategies (like breathing techniques) in calm moments so they’re available during stress
Success indicators: Decreased anxiety before transitions · Smoother movement between activities · Less resistance to change. These may develop slowly over weeks and months — celebrate each step forward.
Create a Transition Routine
Build BridgesConsistent routines create neural pathways that make transitions more automatic and less stressful.10 Think of this as building bridges between activities — the more you build the bridge, the easier it becomes to cross.
- Create simple, repeatable sequences — limit to 3 steps whenever possible
- Use visual checklists that your child can physically mark off as they complete each step
- Keep steps consistent across settings (home, school, community)
- Identify a transition object — a small item your child carries during transitions that signals “we’re moving to something new but I’m still safe”
- Create transition songs, rhymes, or playlists that mark the shift between activities
- Develop special signals — private hand gestures, code words, or emoji texts that communicate “transition time” with dignity
- Start with the easiest transitions first and build from there — don’t start with the hardest
- Gradually increase complexity as each easier transition becomes more automatic
- Celebrate small victories explicitly — “You handled that change really well. I noticed you took a breath and kept going.”
Creative approach: Make your teen’s transition routines fun by turning them into raps, silly songs, or games. Routines act like “training wheels” for transitions — once they know the steps, it becomes smoother and less wobbly for them.
In the long run, you may see your child following routines more independently, reduction in transition times, and showing genuine pride in completing steps. These are real neurological wins — their brain is building new pathways.
Breathing & Redirecting Techniques
Emotional ResetDeep breathing activates the parasympathetic nervous system, calming the fight-flight-freeze response.11 This gives your child an emotional reset button they can access anywhere — at school, in the car, or in the hallway. The key is practicing in calm moments so the tool is available during stressful ones.
- Box breathing (4-4-4-4): Breathe in through the nose for 4 counts, hold for 4, exhale slowly for 4, hold for 4. Repeat 3–4 cycles.
- Balloon breathing: Take a deep breath as though inflating a balloon — hold for a few seconds — then exhale slowly as though reinflating the balloon. The visual metaphor often helps younger children or those who are visual learners.
- Star breathing: Trace a five-pointed star — breathe in on each upstroke, breathe out on each downstroke. Provides a visual anchor that many children find grounding.
- Hallway wind breathing: “Imagine each breath as a gentle wind carrying you, clearing away worries. As you exhale, feel the wind taking any tension with it.” Especially helpful during physical transitions in busy environments.
- After breathing, redirect their attention to something positive or comforting
- Encourage them explicitly: “That was an awesome job getting through that!”
- Ask: “What’s something fun you’re looking forward to next?” This helps shift their mental focus from the loss of the previous activity to the possibilities ahead
- Pair breathing with visualization for longer-lasting calm — a calming place, a favorite memory, or a simple color or shape
Make it theirs: Your child might respond better to “dragon breathing” or “superhero breathing” than “deep breathing.” Let them name it. Let them customize it. The more ownership they have, the more likely they are to use it independently.
Offer Choices to Empower Control
Agency & DignityChoice-making activates decision-making centers in the brain, reducing resistance by creating agency.8 Giving your child a metaphorical “steering wheel” during changes can empower them more than one might think. When our children feel they have some control over how a transition happens, they are far more likely to cooperate with the transition itself. This works across all four profiles.
- Offer 2–3 clear options that guide the transition — not open-ended questions. “Would you like to read a book or go for a walk after dinner?”
- Let them decide the order of tasks: “Do you want to brush your teeth first or put on pajamas?”
- Use positive reinforcement after they make a choice: “Great choice! Now let’s move on to the next fun thing!”
- Critical rule: Ensure all options are ones you can accept. Never offer a choice you aren’t prepared to honor.
- “Would you like to start cleaning up in 5 minutes or 7 minutes?”
- “Do you want to finish your paragraph or your page before we leave?”
- “Should we use the sand timer or the digital timer for packing up?”
- “Would you rather transition at 2:00 or 2:15?”
- “Would you prefer using the back hallway or going through the commons area?”
- “Do you want to leave class a couple of minutes early or wait until the rush dies down?”
- “Would you rather walk with your headphones on or chat while we move?”
- “Do you want to use your phone timer or your smartwatch for tracking?”
- “Would you like James or Sarah to walk with you to your next class?”
- “Do you want to handle this change independently, or do you want me to check in?”
- “Should we text your support person, or would you rather use your strategies solo?”
Private signal system: Create a private signal system with your teen for transitions — like subtle hand gestures or text emojis that mean “need backup” or “I’ve got this.” This allows your child to maintain dignity in front of peers while still getting support when needed.
Keys to success: Keep choices limited (2–3 maximum) · Make all options acceptable · Present them before stress escalates · Use consistent choice patterns · Allow processing time · Celebrate their decision-making · Honor their choices when made. Celebrate the wins when they make appropriate choices, show increased cooperation, and demonstrate better self-advocacy.
Highlighted Intervention: Breathing & Redirecting
“Alright everyone,” Mrs. Jordan said, walking calmly to her desk. She pulled out a familiar blue card with simple breathing steps — a tool Zak recognized from their morning routines. She moved to the smartboard, pulling up a simple five-star image they used for breathing exercises.
“Watch my hand, everyone. We’ll breathe in as we trace up, hold at the point, and breathe out as we trace down. Like blowing out birthday candles — but slowly.”
Zak found his eyes drawn to the predictable pattern of the stars. His hand automatically lifted to trace along something familiar in this sea of change. The tight knot in his chest began to loosen as he followed Mrs. Jordan’s steady counting. “In...2...3...4... Hold at the star point...2...3... Out...2...3...4…”
After five stars, Mrs. Jordan smiled warmly. “Now, who remembers what we learned yesterday about constellations? Before we see them at the planetarium, let’s play our review game — just like we do with worksheets, but this time it’s going to help us be space explorers!”
Zak felt his fingers relax their grip on his desk. Games meant structure, rules, clear expectations — things his brain understood. Mrs. Jordan was building a bridge between his need for routine and this unexpected adventure.
“Zak,” she said gently, “since you know so much about star patterns, would you like to be our first Explorer Captain? You can help us spot constellations on the bus ride.”
As they lined up for the bus, Mrs. Jordan quietly placed a small star chart in his hands — a concrete tool he could hold onto during the transition. “Remember,” she whispered, “you can always find your stars to help you breathe like we practiced. Sometimes, the best discoveries come from the unexpected journeys.”
For our children, an unexpected schedule change isn’t just an inconvenience — it’s like suddenly changing the rules of gravity. Their entire world stops making sense.
Picture this — I’m standing in the hallway of our local school district, my heart pounding as I listen to what happened to my son. A simple change in routine — the kind you and I might handle without thinking — had sent my son into such a profound state of dysregulation that he spent six hours lying motionless on the floor of the client room. Can you imagine your child, overwhelmed to the point of complete shutdown, lying there for hour after hour, not eating, not drinking, not even using the restroom?
The most devastating part? I didn’t find out until the next day, and only because I had to call the school myself after we admitted him to the psychiatric unit. The school casually mentioned, “Oh yes, there was an incident yesterday. We had to change his schedule unexpectedly.”
Let that sink in for a moment — Six hours. No food. No water. No movement. No call home.
For our children, an “unexpected schedule change” isn’t just an inconvenience — it’s like suddenly changing the rules of gravity. Their entire world stops making sense. My son didn’t have the tools to cope with this change, and the school didn’t understand how to support him through it.
I share this not to frighten you but because I want you to know you’re not alone if your child experiences similar reactions to transitions. We’ve lived it. We’ve learned from it. And most importantly, we’ve found ways to prevent it from happening again. No parent should learn about their child’s distress after the fact, and no child should face overwhelming transitions without proper support.

The School Advocacy Script
When talking to teachers: “My child’s transition challenges are neurological, not behavioral. They need [X minutes] of advance notice, a visual schedule, and a calm-down tool available. Can we make a plan for unexpected changes?” Put this in writing and request that it be documented in their support plan.
Morning Routine Framework
Mornings combine the hardest transition (sleep to wakefulness) with the most demands. Build in 15–20 minutes of buffer time, create a visual checklist with 5 steps or fewer, play the same morning music every day as an auditory cue, and eliminate all non-essential decisions before 8am.
The “Preview” Habit
Each evening, preview tomorrow with your child. “Tomorrow we have school, then your appointment, then dinner at home. The only change from today is the appointment — everything else is the same.” This simple habit can dramatically reduce morning dysregulation by giving the brain overnight to process the schedule.
Big Transition Preparation Plan
For major changes (new school, moving, new teacher): begin verbal preparation 4–6 weeks ahead. Visit the new place before the first day. Meet key people. Create a visual story of the change. Write down 3 things that will stay the same. Identify one “anchor” in the new setting your child can count on.
Sensory Transition Kit
Assemble a small portable kit: noise-canceling earbuds or headphones, a favorite small fidget, a laminated visual schedule card, a written list of 3 breathing steps, and a photo of a calming place. Keep it in their backpack. Knowing it’s there reduces anxiety even when it isn’t used.
When a Transition Goes Wrong
First: don’t correct, lecture, or discuss during the meltdown. Presence without pressure. Once calm returns (not during): “That was really hard. What would have helped?” Then adjust. Every difficult transition is information about what support was missing — not evidence of your child’s character.
Several brain regions work together to manage transitions. Understanding these helps you have more informed conversations with doctors, therapists, teachers, and social workers about why your child struggles — and what kinds of support actually match the underlying neurology.
From the Book
Anterior Cingulate Cortex (ACC)
The Change Detection Center
Its Role: Monitors changes in the environment and routine. When it is not working the way it should, it can lead to heightened stress response to change, difficulty processing how to manage transitions, and emotional dysregulation during shifts.18
Creating “change buffers” — predictable routines and warnings — helps your child’s ACC prepare for transitions rather than treating them as emergencies.
- ASD: May show extreme reactions to minor changes in routine19
- ADHD: Demonstrates inconsistent responses to transition cues
- FASD: Exhibits heightened stress response to routine changes20
- Trauma: Shows hypervigilance during transitions21
Limbic System
The Emotional Memory Center
Its Role: Weaves together past experiences with present situations, creating meaningful connections that help us navigate change. It orchestrates emotional responses based on archived memories while managing anticipatory anxiety — the forward-looking nervousness we feel approaching unfamiliar situations.24,25
Helping your child build a “library” of positive transition experiences as a reference can help reduce the chaos in the home over time.
- ASD: May develop intense anxiety about transitions based on past experiences26
- ADHD: Shows variable emotional responses to similar transitions27
- FASD: Struggles to learn from past transition experiences28
- Trauma: Exhibits heightened emotional responses to transition triggers29
Basal Ganglia
The Routine Manager
Its Role: Orchestrates daily routines like a skilled conductor, guiding automatic behaviors while helping us learn new patterns and smoothly transition between familiar habits as needed.32
Building consistent transition routines helps them become “automatic” over time — reducing the cognitive demand of each transition significantly.
- ASD: Shows strong adherence to established routines33
- ADHD: Difficulty establishing consistent transition routines34
- FASD: Struggles with developing automatic transition behaviors35
- Trauma: May show disrupted routine patterns during stress36
Additional Brain Regions — Website Expanded Content
Prefrontal Cortex
The Transition Control Center
Its Role: Manages when and how your child switches between tasks, helps them adapt to new situations, controls their responses during changes, and maintains the mental flexibility needed to handle shifting demands.11
- ASD: Shows rigid thinking patterns, making transitions particularly challenging12
- ADHD: Struggles with executive function, affecting smooth transitions13
- FASD: Exhibits difficulty with mental flexibility and shifting attention14
- Trauma: May demonstrate stuck behaviors when faced with change15
Amygdala & Orbitofrontal Cortex
The Emotional Regulation & Adaptation System
Its Role: The Amygdala asks, “Is this change safe or dangerous?” The OFC responds, “How should I react?” When underdeveloped, this system produces emotional dysregulation, meltdowns over change, and anxiety about transitions across all settings.
- Emotional dysregulation during transitions — meltdowns over what appears minor
- Overreacting to abrupt changes; difficulty calming after a transition disruption
- Struggling to regulate emotional responses when new situations arise
Hippocampus
The Memory & Routine Processing Center
Its Role: Stores past experiences to help predict and prepare for transitions. Links new changes to familiar patterns. When underdeveloped, children have difficulty remembering transition routines and fear unfamiliar situations even when they’ve navigated them before.
- Difficulty remembering how a transition went last time — no transfer of prior success
- Intense fear of unfamiliar situations even when they’re not new
- Repetitive questions (“What are we doing?”) as the brain tries to anchor to known information
Insula
The Body-Mind Bridge
Its Role: Processes internal body signals tied to stress and readiness for change. Helps identify when it’s time to shift from one state to another. Acts as the body’s intuitive interpreter — decoding bodily signals and bridging physical and emotional states during transitions.46
- ASD: Shows heightened sensory responses during transitions47
- ADHD: May miss body signals indicating stress until it’s too late48
- FASD: Struggles with sensory integration during changes49
- Trauma: Exhibits increased body sensitivity — physical discomfort as a stress signal50
Parietal Cortex
The Spatial & Sensory Awareness Hub
Its Role: Helps your child understand body position in space and navigate new environments. Supports problem-solving related to spatial awareness during transitions. When underdeveloped, children have difficulty processing new environments and struggle with physical transitions (e.g., moving from one room to another, navigating crowded hallways).
- Difficulty processing new environments — even familiar places feel disorienting during a transition
- Bumping into objects or people, dropping items during transitions
- Struggling with physical transitions involving movement, stairs, or crowded hallways
Cerebellum
The Timing & Coordination Center
Its Role: Regulates the timing and sequencing of both physical and emotional responses during transitions. Helps your child know when to begin a transition and how to sequence the physical movements that go with it.
- ASD: May show delayed motor responses during transitions40
- ADHD: Struggles with the timing of transition sequences41
- FASD: Exhibits difficulty with motor planning in transitions42
- Trauma: Shows disrupted timing patterns under stress43
Default Mode Network (DMN)
The Self-Awareness System
Its Role: Keeps watch over our inner world during transitions, like a mindful guardian. It monitors our internal landscape, processes shifts in our environment, and maintains our sense of self through life’s changes.53
- ASD: May show reduced self-monitoring during transitions54
- ADHD: Struggles with self-awareness during changes55
- FASD: Exhibits difficulty maintaining self-awareness during shifts56
- Trauma: Shows disrupted self-awareness under stress57

Sometimes, our children struggle to recalculate the route during the day because their mental GPS can go offline during changes. Think of it like a complex traffic intersection where multiple roads converge — just as a skilled traffic controller needs to coordinate the flow of vehicles from different directions, your child’s brain must orchestrate multiple mental shifts during transitions. It’s like a GPS that needs to recalculate the route while still in motion.
- The brain’s executive functioning and sequential processing abilities directly affect transition success.
- Your child might handle individual activities well but struggle when switching between them.
- Help your child build step-by-step roadmaps between current and upcoming activities, breaking the journey into manageable segments.33
Sometimes words get lost in translation when your child’s internal translator misses verbal transition warnings — they need to understand multi-step instructions at a rate that is too fast, express their anxiety or concerns, and ask for help that they often don’t know how to do all that well. The challenge isn’t just understanding words but processing them during the stress of change.34
- Matching your communication style to your child’s processing speed is important.
- Use simpler words, fewer steps, and give more wait time.
- Instead of “Time to clean up,” try “In 5 minutes, can you vacuum?” This became a game-changer for us. (Joel)
Your child has an internal project manager called Executive Function that controls changes and can sometimes get overwhelmed with too many moving parts. They must stop the current activity (inhibition), start the next activity (initiation), remember the transition steps (working memory), and adjust to changes (flexibility) — all simultaneously.
- What we think is a simple transition can escalate into a complex multi-step task for our children — causing them to feel overwhelmed.35
- Executive function works like a control tower coordinating multiple skills. Planes need clear landing and takeoff instructions — your child needs clear signals for stopping one activity and starting another. (Make a list with only three steps.)
- Stress acts like interference in the communication system. When anxiety rises, the ability to process and execute transition steps diminishes — even familiar routines become challenging.
Your child’s mental spotlight system must turn off one beam and redirect to something new. Getting stuck or scattered between tasks can include challenges in disengaging from the current activity (letting go), holding focus during the change itself (staying present), filtering out competing distractions (maintaining clarity), and engaging with the new activity (connecting anew).
- “Attention lock” on preferred activities can make it genuinely difficult for children to redirect even when they understand they need to.36
- Environmental stimuli during transitions can scatter attention before the transition is even complete.
- Think of attention during transitions like helping your child steer a boat — sometimes they need help turning the wheel, maintaining course, and setting direction toward the new destination.
This is our child’s emotional temperature control during changes — which sometimes overheats under pressure. During transitions, your child needs to manage anxiety about change, control frustration when interrupted, handle unexpected shifts, and regulate emotions in new situations.
- Morning routines are particularly challenging as children move from sleep to wakefulness, processing multiple sensory changes while regulating their emotional state as they anticipate the day.37
- Shifting between structured and unstructured activities (e.g., classroom work to gym) can trigger emotional dysregulation as both the activity type and emotional demands change simultaneously.
- Social transitions — joining new groups or changing classes — combine both environmental and interpersonal changes, making them doubly overwhelming.
Our children have a physical coordination system that needs to engage during changes — sometimes moving in slow motion or stumbling under pressure because of their unique wiring. During transitions, the body must coordinate physical movements, navigate new environments, handle materials and belongings, and adjust to different physical demands.
- Our children may bump into objects or people, drop items, or become overwhelmed by the need to coordinate movements while simultaneously processing environmental changes and managing their belongings.38
- Fine motor tasks during transitions — packing materials, zipping backpacks, organizing supplies — can present significant challenges and contribute to overall dysregulation.
- Motor skills: If your teen needs extra time and space for physical transitions to avoid accidents and anxiety, allow for the time needed. (Motor skills were never an issue for our son, which was, in part, why understanding his FASD profile was hidden from us. — Joel)
Additional resources are available on our website. Log in and navigate to Chapter 9 to access visual schedule templates, transition routine planners, school advocacy letter templates, and supplemental tools for parents and educators.
In the next chapter, we’ll examine the Core Conversation: Perseveration — Danger Zone. Understanding why our children get stuck in repetitive thoughts and behaviors is the next essential piece of this journey.
