Behaviour Is Communication: Why Kids Do Well If They Can

Most parents have stood in this moment: a meltdown at pickup, a refusal to get dressed, a sudden shove towards a sibling over a toy that was fine to share five minutes earlier. In the moment, it's easy to read these as defiance, rudeness, or a child testing limits on purpose. Two ideas from occupational therapy offer a different, more useful way to understand what's actually happening: behaviour is communication, and kids do well if they can. Once a parent understands both, a lot of the daily guesswork around behaviour starts to make sense.

What "behaviour is communication" actually means

Children develop the ability to explain their internal state, what they're feeling, why they're struggling, what they need, much later than they develop the capacity to act on it. A four-year-old's nervous system can register overwhelm long before that child has the vocabulary or self-awareness to say "I'm overstimulated" or "I don't know how to start this." So the feeling comes out sideways: as a meltdown, a refusal, a bolt away from the situation, or a physical reaction like hitting or throwing.

Adults do the same thing when their capacity is stretched. Someone who snaps at a partner after a hard day rarely means the snap literally; it's usually stress, exhaustion, or overwhelm finding the fastest exit. Children have far less practice regulating that process and far fewer tools to do it with, so their version of the "snap" tends to be bigger, more frequent, and harder to read.

Understanding behaviour this way means treating it as data rather than a problem to shut down. A meltdown at pickup after school often reflects sensory and social demands that built up all day finally being released somewhere safe. A refusal to get dressed can mean a transition feels too fast, or that a piece of clothing is genuinely uncomfortable. A push towards a sibling can happen when a child has a wave of frustration and no words ready to meet it. Each of these is a child's system telling you something has become too much, too fast, or too unclear, and the job is to work out what.

Where "kids do well if they can" comes from

This phrase, and the framework behind it, comes from Dr Ross Greene, a clinical psychologist who developed the Collaborative and Proactive Solutions (CPS) model after years of working with children described as explosive, oppositional, or non-compliant. Greene's core argument, laid out in his book The Explosive Child, is that challenging behaviour is best understood the same way we understand a learning difficulty: as a sign of a skill that hasn't developed yet.

Greene calls these missing skills "lagging skills," and they typically sit in areas like flexibility, frustration tolerance, emotional regulation, and problem solving. A child with a lagging skill in flexibility will genuinely struggle every time a plan changes at short notice, because shifting expectations quickly is a skill they haven't built yet. A child with a lagging skill in frustration tolerance will hit a wall fast when something doesn't go their way, because their capacity to sit with that discomfort hasn't developed to match the demands placed on them.

This reframe changes the core question a parent asks. The useful question becomes: what's getting in the way of this child doing what's expected? That single shift moves a parent from managing behaviour after it happens to understanding and building the skill before it becomes a daily flashpoint.

How this shows up day to day

The pattern is easiest to see in specific moments. A meltdown at school pickup, for many kids, has very little to do with the pickup itself. It's the release valve after a full day of holding things together in a classroom, a day that demanded sitting still, following instructions, managing social dynamics, and coping with noise and light, all without a real break. By the time a familiar adult arrives, the nervous system finally has permission to let go, and it often does so loudly.

A refusal to start homework can look like laziness or defiance from the outside, but it's frequently a child who genuinely doesn't know where to begin. The task feels too big, too open-ended, or too hard to break into steps, so the child avoids, stalls, or melts down. A big reaction to a last-minute change of plans, a cancelled outing, a different route to school, a new person at pickup, usually points to a real struggle with flexibility. And when a child hits or pushes a sibling, it's often because a wave of anger or frustration has arrived faster than the words needed to express it.

Every child is different, so the same behaviour can point to different things in different kids. Understanding the individual child in front of you is what makes the response effective.

How this changes your response

Recognising the "why" behind a behaviour doesn't mean lowering expectations or removing consequences altogether. A child still needs to learn to manage frustration, cope with change, and get along with siblings. What changes is how that learning happens. Skills grow through regulation, practice, and consistent, calm support over time.

This is where the principle of regulation before expectation becomes useful. A dysregulated nervous system, one that is flooded with stress hormones and running on a fight, flight, or freeze response, cannot access the parts of the brain responsible for calm thinking, listening, or problem solving. Asking a child to reflect, apologise, or problem-solve while they're mid-meltdown is asking them to use a part of the brain that has temporarily gone offline. Helping a child settle first, through movement, quiet, physical pressure, or simply staying calm and present nearby, is what allows the thinking brain to come back online enough for real learning or conversation to happen.

None of this replaces structure. Kids still need consistent routines, clear expectations, and firm boundaries around safety. Understanding behaviour as communication sharpens where that structure needs to focus. Over time, a parent starts noticing patterns behind repeated meltdowns: transitions are the trigger, or hunger and fatigue make everything harder after 4pm, or a certain sensory environment consistently overwhelms. That pattern becomes something to plan around, not just react to.

How occupational therapy applies this

An occupational therapist works from exactly this lens. Sessions start with the question underneath the behaviour: what is making a particular expectation hard for this specific child, and is it sensory, motor, emotional, or environmental? From there, therapy focuses on two things at once: building the missing skill through play-based, engaging activities, and adjusting the environment so a child can succeed while that skill develops.

Parent coaching sits at the centre of this work, because the skills built in a session only matter once they carry into daily life at home. A parent who understands what a meltdown, a refusal, or a physical outburst is signalling is far better placed to respond in the moment, and far better placed to notice progress that might otherwise go unseen. Small shifts, a transition that used to end in tears now ending in grumbling, a homework session that starts five minutes faster, are real markers of a skill developing, even before the bigger behaviour fully resolves.

Frequently asked questions

Does "kids do well if they can" mean there are no consequences? No. It shifts the focus from punishing a behaviour to building the skill behind it. Natural and logical consequences still have a place alongside teaching the skill a child is missing.

What if my child's behaviour feels deliberate? Big feelings can look calculated in the moment, especially when a behaviour has worked before to get a need met. Looking for the skill gap or unmet need underneath the behaviour almost always reveals a child who is struggling, and starting there gets better results than assuming defiance.

How do I stay calm when my child is dysregulated? Co-regulation, a calm adult nervous system helping a child's nervous system settle, is one of the most powerful tools available in these moments. It's also a skill that develops with practice, and it's something an occupational therapist can help build strategies around.

Can this approach still include boundaries and routines? Yes. Structure and understanding work together. Clear, consistent routines give a child the predictability they need, while understanding the behaviour helps a parent know exactly where the extra support needs to go.
