Why Transitions Are Hard: What the Neuroscience Tells Every Therapist
It is one of the most common moments in any paediatric session. A child is settled, engaged, and doing well. Then it is time to pack up and it feels like everything falls apart.
As therapists, we look deeper below the surface. Our therapist lens says: this is not a behaviour problem. It is a nervous system responding to a genuine demand. Understanding why transitions are hard (from a neuroscience perspective) changes everything about how we approach them in practice.
What a Transition Actually Asks of the Brain
When we ask a child to transition, we are not asking them to do one simple thing. We are asking them to do several complex things simultaneously:
Stop an ongoing activity.
Shift their attentional focus.
Let go of a plan or expectation they had formed.
Adjust to a new set of demands.
Prepare cognitively and emotionally for what comes next.
That is a significant executive functioning load. It involves inhibition, cognitive flexibility, working memory, and emotional regulation all at once. For many of the children we work with, any one of those demands is already challenging. Combining all of them in a single moment can push the system past its capacity.
The Brain Likes Predictability
From a polyvagal perspective, the nervous system is constantly asking one question: is this safe? Predictability is one of the primary signals of safety. When the environment is consistent and the sequence is known, the nervous system can relax into lower arousal states that support engagement and learning.
Transitions interrupt that predictability. They introduce uncertainty: where are we going? What will happen next? How long will it take? Will it be hard? For a child whose nervous system is already running at higher arousal, that uncertainty can feel genuinely threatening; not because they are being dramatic, but because that is how the threat-detection system is wired.
It Is Not About Leaving Something Fun
Here is the reframe that changes things. When a child resists a transition, it is easy to assume they are attached to the activity itself. e.g., the game, the toy, the screen. But what they are often leaving is not the activity. It is a state of regulation.
Whatever they were doing had become comfortable, predictable, and safe for their nervous system. It was something they understood, something they could manage. That is regulation. Asking them to leave it is not just asking them to stop a fun thing. It is asking them to leave a physiological state and enter uncertainty.
"When a child resists a transition, they are often not leaving something fun. They are leaving a state of regulation."
Capacity Shrinks Under Stress
Stress reduces the resources available for flexibility. A child who arrives at your session already tired, hungry, overstimulated, or emotionally depleted has fewer cognitive resources to draw on when a transition arrives. Their window of tolerance is narrower. Their threshold for dysregulation is lower.
When we see a child "overreacting" to a transition, what we are often seeing is a brain that has run out of capacity. The demand was not unusual but the resources were not there to meet it.
This reframe matters clinically. It shifts us from asking "why can't they just do it?" to "what is available in their system right now, and how do we support the transition from here?"
What This Means for Practice
Understanding transitions as a nervous system event (not a behaviour choice) changes how we plan for them. Preparation reduces uncertainty, which reduces threat. A transition that is predictable is less dysregulating than one that arrives without warning.
Language matters too. Collaborative, low-demand language that preserves some sense of autonomy keeps the nervous system more open. "We are going to finish up in two minutes" builds in prediction. "Would you like to put it away yourself or shall we do it together?" preserves choice.
Timing matters. A child who is at peak engagement or in a complex activity is harder to move than one who has reached a natural pause. Session planning that builds in natural transition points creates less friction.
And context matters enormously. What happened before the session, what happened at school, whether the child is hungry or tired or overstimulated... all of it affects how much is available when the transition comes.
