Children, Regulation, and the Nervous System

Children are not born knowing how to regulate their emotions.

Intuitively, I always knew they were feeding off my energy. At least that was the language I had for it. I knew that when they were babies, if I pretended to be calm while I rocked them back to sleep at 2 am, something in them would eventually settle. Even though Fin didn’t actually like being rocked. He preferred being stomped up and down the passage, which was not exactly the most calming experience for me. So, there I was, doing what I can only describe as a half-asleep running man, carrying a very determined baby up and down the hallway, trying to hold onto some version of absolute tranquillity while my body was screaming otherwise. And somehow, he would fall asleep. When children become overwhelmed, they borrow the regulation of the adults around them. Before children can calm themselves, someone must help them feel calm.

 Even a 5-month-old isn’t “thinking” about what is happening, but their nervous system is constantly responding to it. Whether they settle or escalate depends on whether they feel soothed, held, and regulated through another nervous system. At that age, regulation is still something that happens between us, not within them. And when that load tips past what they can manage alone, what we often see is what looks like distress — but is really an immature system asking for help it doesn’t yet have the capacity to generate internally.

Why Children Dysregulate

This is really the heart of why children dysregulate: their nervous system has decided that something feels too much, too fast, too uncertain, too threatening, or too overwhelming for the resources they currently have available. That “something” might be obvious to us, or it might seem completely ridiculous from the outside. The key is that the nervous system responds to perception, not objective reality.

From Co-Regulation to Everyday Behaviour

 As children grow, co-regulation starts to look very different. It shifts from the 2 am passage walks, the rocking, and the holding, into everyday moments that don't always look like regulation at all.

In fact, some of the moments parents worry about most are actually the moments that tell us a child finally feels safe enough to stop holding everything together. It's the child who comes home from school and explodes over a snack wrapper, loses it over homework, or becomes tearful, argumentative, clingy, or impossible at bedtime. From the outside, these reactions can seem completely out of proportion to what is happening in the moment.

 But often, the snack wrapper isn't really the problem. The homework isn't the problem. Bedtime isn't the problem. What we may be witnessing is a nervous system that has spent the entire day coping. Holding itself together. Adapting to social expectations, classroom demands, sensory input, disappointments, frustrations, and the countless small stresses that accumulate over the course of a day.

Then home arrives. 

Home is often the place where children no longer have to work quite so hard to keep everything contained. It is where the bracing can begin to soften and where the nervous system can finally start letting go of what it has been carrying. What looks like a sudden outburst is often a delayed stress response — the release of everything that could not be expressed while they were busy coping.

 This doesn't mean we celebrate every behaviour that follows. Boundaries still matter, and respect still matters. But understanding what may be sitting underneath the behaviour changes how we respond to it. Instead of seeing only the explosion, we begin to recognise the effort that came before it.

 And this is where co-regulation becomes less visible, but perhaps even more important. The child is no longer a baby being rocked to sleep in your arms, but they are still borrowing something from you. Your steadiness. Your presence. Your ability to help them find their way back to safety.

 To us, it no longer looks like rocking or holding a five-month-old baby. But to their nervous system, it is still the same thing. Us not escalating when they escalate, our tone staying grounded when theirs is not, and slowing the moment down instead of speeding it up.

 It is still holding.

 It is still rocking.

Just without the arms.

How Behaviour Begins to Look Different

 Once I understood this, I started seeing behaviour differently.

 When a child feels safe, we rarely spend much time analysing their behaviour at all. They're busy being children: playing, exploring, asking endless questions, creating imaginary worlds, negotiating with siblings, and chatting about things we never asked to hear about. They're curious about the world around them and engaged with life in a way that feels natural and effortless.

 But when the nervous system detects danger, something changes.

 For some children, that change looks big. They become louder, faster, and more reactive. They argue, push back, become impulsive, controlling, restless, anxious, or explosive. For others, the shift is far quieter. They retreat into themselves and become withdrawn, disconnected, exhausted, or suddenly seem as though they don't care about anything at all.

 On the surface, these children can appear completely different from one another. One may be storming around the house slamming doors, while another sits silently in their room refusing to engage. But beneath those very different behaviours, the nervous system may be trying to achieve exactly the same thing.

 Protection.

The Brain’s Alarm System and Safety

 Learning about Polyvagal Theory helped me make sense of this. Dr Stephen Porges described how our nervous systems are constantly moving in response to cues of safety and danger. When we feel safe, we naturally move towards connection. We become more available for relationships, learning, creativity, curiosity, and play. When we feel threatened, the nervous system shifts towards protection.

 What I found particularly helpful was understanding (in myself and my children) that protection doesn't always look the way we expect it to. It could look like fighting, or maybe it looks like running away from a situation. Sometimes it looks like freezing, shutting down, withdrawing, or going quiet. Different children (and adults) express these protective states differently, but the underlying purpose is often the same: the nervous system is trying to keep them safe.

 For me, this understanding changed the questions I asked.

Instead of asking, "What's wrong with this child?" I began asking, "What might this child's nervous system be responding to right now?"

That one question can soften so much of the frustration that arises when we view behaviour in isolation. It invites curiosity where judgment might otherwise appear. It reminds us that underneath every behaviour is a nervous system doing what it was designed to do.

Stay safe.

Building Emotional Resilience

 The good news is that children do not build resilience by avoiding stress, disappointment, frustration, anxiety, or overwhelm. As much as we might wish otherwise, these experiences are part of being human. I know there were countless moments when I wanted to remove the obstacle, fix the problem, or take away whatever was hurting my boys.

Looking back, I understand that resilience isn't built in the absence of challenge, but in facing challenges and discovering that we can navigate them. And perhaps even more importantly, discovering that we don't have to do it alone.

Every time a child becomes overwhelmed and is supported back towards safety, something significant is happening beneath the surface. The nervous system is learning that difficult feelings can be survived, that stress eventually passes, that support is available, and that connection can still exist even in hard moments.

Over time, these experiences accumulate. A difficult friendship. A disappointing result. A hard day at school. A moment of failure. None of these experiences feel good in the moment, but each one offers an opportunity for the nervous system to learn something valuable: "I've felt this before. I got through it. I wasn't alone. I can cope."

The more I work with children and families, the more I believe this is one of the greatest gifts we can offer. Not a life without challenges, perfect regulation, or constant happiness. But the repeated experience of finding safety again after moments of overwhelm.

Co-Regulation in Real Life

So what does this look like in real life?

 The answer is often far simpler than parents expect.

 One thing I have come to realise through my own parenting journey is just how difficult it can be to create the space for regulation in modern family life. Speaking from my own experience as a mother, even with support around me, the demands can feel relentless. Running a household, ferrying children from one activity to the next, grocery shopping, navigating relationships and friendships, trying to stay healthy, finding time for the things that nourish your own soul, and working enough to cover it all can leave very little room to simply slow down and be present.

I know this because I have lived both sides of it.

 There was a time when life felt like a constant rush from one responsibility to the next. Looking back, I can see how easy it was to miss the subtle signs that one of my boys was struggling. Not because I didn't care, but because I was moving so fast that I didn't always have the capacity to notice what was happening beneath the behaviour.

 Over time, I have made some deliberate changes. We cut back on certain luxuries, adjusted our lifestyle, and prioritised creating more space and availability within our family life. It wasn't always easy, but the benefits are immeasurable. I have experienced first-hand the value of being grounded enough to recognise when my children need me, especially since they haven't yet had the language, insight, or experience to regulate themselves.

Sometimes we can only recognise dysregulation- in ourselves and in our children- when we slow down enough to truly see it. And then, when we do notice that something feels off, our first instinct is often to explain, correct, lecture, negotiate, or solve the problem. Yet in those moments, what children usually need first is not reasoning. They need regulation.

This means offering our own nervous system as an anchor while theirs is finding its way back. And that becomes much harder when we are rushing through life ourselves.

 Just softening our voice or simply sitting beside them without rushing to fix anything. Sometimes it means stepping outside together, going for a walk, taking a swim, cuddling on the couch, sharing a laugh, or just quietly staying present while the storm passes.

For younger children, co-regulation may look like physical closeness, movement, rhythm, play, or touch. For older children, it might be less obvious. A car ride with some (neutral) tunes. Making hot chocolate together. Going on a side quest for ice cream. Listening to them without immediately offering solutions or merely being nearby while they process a difficult day.

 The specific tool matters less than the message underneath it.

And the message is this:

"You are safe."

 "You don't have to carry this alone."

 "We will get through this together."

 Over time, these small moments become the building blocks of regulation. Long before children learn to calm themselves, they learn what calm feels like through their relationships with us.

And perhaps that is the real power of co-regulation. It is not a technique. It is a relationship.

One worth truly investing our time in.
