You said it was time to leave the park five minutes ago. You have said it three more times since. Your child is still on the swing, and the next thing that happens is going to be loud.
Or it is the bath, or the tablet, or the walk from the car into the grocery store, or simply moving from the kitchen table to the front door with shoes on. Caregivers of neurodivergent children often find that the hardest parts of a day are not the activities. They are the seams between them.
This is worth understanding, because a transition that looks like refusal is usually something else entirely.
A transition costs more than it looks
From the outside, stopping one thing and starting another looks like a single small step. Inside, it is a stack of them. A child has to pull attention off what they are doing, hold on to where they are meant to go next, picture what it will be like, plan the first move, and manage whatever they feel about losing the thing they were enjoying. That set of mental skills is usually called executive function, and shifting between tasks is one of the pieces of it that many autistic and ADHD children find genuinely expensive.
Expensive is the right word. It is not that the child cannot shift. It is that shifting costs them more than it costs the adult asking, and the adult is often on their fourth transition of the hour without noticing they have made any at all.
Attention as a tunnel, not a spotlight
One of the most useful ways to think about this comes from autistic researchers rather than from a clinic. Dinah Murray, Mike Lesser and Wenn Lawson described autistic attention as monotropic: attention that flows strongly into a small number of channels at a time, rather than spreading thinly across many. Fergus Murray puts the everyday version of it well. Interests pull autistic people in strongly and persistently, which can be a real asset, and which also means coming out of a tunnel is not the same as glancing away from a spotlight.
Seen through that lens, a lot of behavior at transitions stops looking like defiance. A child deep in a channel of attention is not ignoring you. They are somewhere that takes real effort to leave, and the request to leave it arrived without warning from outside the tunnel.
Uncertainty is the other half
The second half is what comes next. Many autistic children have a strong preference for predictability, and researchers studying anxiety describe a related trait called intolerance of uncertainty, meaning a tendency to experience not knowing as threatening rather than neutral. In one study of autistic and non-autistic children, intolerance of uncertainty and anxiety together explained roughly half the variance in the autistic children's sensory sensitivities, and intolerance of uncertainty remained a predictor even after anxiety was accounted for.
More recent work asking autistic students, parents and school staff what actually makes school hard puts unpredictable transitions near the top of the list, alongside fear of the unknown and the unpredictability of social situations.
So a transition asks two hard things at once. Leave a place you are absorbed in, and step into one you cannot fully picture. It makes sense that children resist. Most adults would.
What tends to help
None of what follows makes transitions free. The aim is to make them cheaper.
Warn, and make the warning something they can see. A verbal countdown works better when it is paired with something visible or audible: a timer, a picture, a card, a song that ends. A classic study by Sarah Dettmer and colleagues found that visual supports cut the delay between the instruction and the child actually starting the next activity.
Show what comes next, not just what is ending. Uncertainty is half the problem, so fill it in. First shoes, then car, then Grandma's. A short sequence a child can look at is doing more work than the same words spoken twice.
Let them carry something across. A toy, a card from the last activity, a job to do on arrival. A bridge object gives a child something continuous to hold while everything else changes.
Offer a real choice inside the transition. Not whether to leave, which is not on offer, but which coat, which door, walking or carried. A small amount of control in a moment that has none is often enough.
Respect the tunnel where you can. Where it is possible, time the request for a natural seam: the end of an episode, the end of a level, the end of a lap. When it is not possible, say so plainly and expect the exit to cost something.
Build in landing time. Arriving somewhere is its own transition. A few unhurried minutes at the other end, with no demands in them, is often what makes the next hour work.
Keep your own pace slow. The adult's steadiness is part of the support. Fewer words, a lower voice, and no rush in your body give a child something to borrow from while they make a hard shift.
What the evidence honestly shows
Visual supports are well established, and it is worth being precise about what they do. A 2009 study by Waters, Lerman and Hovanetz found that visual schedules on their own did not reduce problem behavior when children moved from a preferred activity to a non-preferred one, and that other elements of the plan were doing the work. A 2025 review in Behavioral Interventions looked specifically at whether the visual schedule component of these packages can be credited for the improvement, and concluded that the research has rarely tested that component by itself.
The practical reading is not that visual supports do not matter. It is that a picture card is not a lever. Predictability, preparation, choice, pacing, and a calm adult all move together, and the child in front of you is the only real test of which parts help.
One honest note
A predictable environment and a familiar companion can help a child feel safer at the seams of the day, and a calmer setting can make a hard shift a little less costly. That is not treatment, and nothing we are building at SEPA Babies diagnoses, treats, or replaces a caregiver's presence or professional support when a child's distress is frequent, severe, or getting in the way of daily life.
The reframe worth keeping is small and it changes a lot. A child stuck at a transition is not giving you a hard time about leaving. They are paying a price you cannot see, for something you did not have to pay for at all.
