If you want to predict when behaviour will spike in your preschool or childcare room, watch the transitions.
Not the learning activities. Not the messy play. The in-between moments — the switch from free play to mat time, from outside back to the room, from building blocks to tidy-up. That’s the cliff edge. That’s where the melts happen, the refusals, the running, the throwing.
It’s not a coincidence. Transitions are structurally hard for under-5s, and understanding why makes it easier to get ahead of them.
Why Transitions Hit So Hard
Transitions are hard for young children because they collapse two problems into one moment.
First, the child loses something preferred. They’re mid-build, mid-pretend, mid-something that matters to them — and now it has to stop. That’s a loss of access to a reinforcing activity.
Second, they’re being asked to move toward something that’s less preferred, or unknown, or actively unwanted. Tidy-up is dull. Mat time means sitting still. Lunch means leaving the water table.
From a behaviour analysis perspective, that’s a double hit: escape from the non-preferred activity is blocked, and the preferred activity is removed. The behaviour that results — throwing, going limp, running, screaming — typically functions as escape. It delays the transition. It works.
You can read more about how functions drive early-years behaviour in the function of behaviour glossary entry.
Under-5s Have No Usable Sense of Time
Adults understand “five minutes” because they’ve lived it thousands of times. They can feel the gap between now and soon.
Children under five genuinely cannot. “Almost time to pack up” lands as meaningless noise. “We’ll do that again tomorrow” offers no real comfort because tomorrow is an abstraction. When a three-year-old refuses to leave the sandpit, they’re not being defiant — they’ve heard words with no attached meaning, and the concrete experience is that something they love is about to disappear.
This matters because a lot of transition strategies assume children can hold time in mind. They can’t. Support has to be concrete, visual, and sequential — not verbal reassurance about what happens later.
Make Time Visible
The most reliable antecedent approach to hard transitions is making the structure of the day visible and predictable.
A visual schedule on the wall — pictures of each activity in order — gives children a concrete map. They can point to “now” and “next”. The transition isn’t something that happens to them out of nowhere; it’s the next picture on the board.
This works because predictability reduces the threat. If a child can see that outside comes before lunch, and lunch comes before rest, the move from outside to lunch isn’t a surprise. The protest drops because the information is already there.
There’s a full breakdown of the research behind this in Visual Schedules: Why They Work, and the visual schedule glossary entry explains the core concepts. For implementation steps specific to early childhood settings, the visual schedules antecedent strategy guide covers what to put on the board and how to teach children to reference it.
Warn Before You Switch
A visual schedule tells children what the day looks like. Transition warnings tell them that the switch is coming.
Give a warning before every transition. Two warnings work well for most early childhood rooms: a five-minute warning and a two-minute warning. Make them specific: “Five more minutes of building blocks, then it’s tidy-up time.” Say it calmly, once — you don’t need to repeat it multiple times or escalate it.
A sand timer is more useful than a verbal countdown for children who can’t hold numbers in mind. They can see the time draining. When the timer runs out, tidy-up starts — the timer is the authority, not you.
A tidy-up song is worth considering for nursery and preschool settings. A consistent, predictable song means children hear it starting and know — without anyone telling them — that the transition is beginning. The song becomes a conditioned cue. It’s low-effort, and in rooms where it’s been used consistently, children often begin cleaning up before the song is halfway through.
The transition warnings strategy guide has specific steps for introducing these in a room that isn’t used to them yet.
First/Then Across the Transition
When a child is actively resisting a transition, a First/Then frame can help get movement started without a long negotiation.
“First tidy-up, then snack.” “First mat time, then outside.”
It’s not a bribe — you’re not adding something that wasn’t already happening. You’re naming the sequence in a way that connects the non-preferred step to the preferred one that follows. For children without a strong grasp of time, this gives the transition an endpoint they can hold in mind.
Use it as a bridge, not a rescue. The First/Then is most useful when you introduce it proactively, before the resistance peaks. Once a child has already refused and is dysregulated, language-heavy reasoning rarely lands.
If your room doesn’t have a First/Then board, the First/Then board template is a printable version you can laminate and use with velcro picture cards.
Setting Events That Load the Problem
Transitions don’t happen in isolation. How hard a child finds a transition on any given day is influenced by what happened before they walked in the door.
A child who didn’t eat breakfast will find tidy-up harder. A child who didn’t sleep will have less capacity to regulate. A child who had a difficult morning at home is already carrying a load before a single activity starts.
These are setting events — background conditions that alter how a child responds to the antecedents and consequences they encounter throughout the day. A setting event doesn’t cause the behaviour directly, but it lowers the threshold. The same transition that a well-rested, well-fed child moves through without issue can trigger a full meltdown in the same child on a hard morning.
Understanding setting events is useful because it changes what you look for. If a child’s transitions are suddenly much harder this week, ask what’s changed in the background first — illness, family disruption, a sleep regression. You can read more at the setting event glossary entry.
This also points to a practical strategy for nursery and childcare staff: a brief handover at drop-off that captures anything unusual at home gives the room team early warning. Even a quick note on a board — “rough night, haven’t eaten much” — changes how you approach that child’s morning.
What to Expect When You Start
Transitions rarely become easier overnight. When you introduce a visual schedule or start consistent transition warnings, children who have learned that protest delays the transition may initially escalate — because the old strategy still feels like it should work.
Hold the structure anyway. The warning still ends. The tidy-up song still starts. The schedule still moves forward. The consistency is the intervention.
Most children respond within a few weeks of a routine being genuinely consistent. The ones who take longer are usually the ones with the most history of the transition being delayed by their protest — which is useful information. It tells you the function is escape, and the behaviour has been working reliably. That takes longer to shift, but it does shift.
The strategies here won’t eliminate every hard transition. Under-5s are under-5s. But the combination of predictability, visible time, advance warning, and clear First/Then sequencing removes most of the conditions that make transitions harder than they need to be.
