Children don’t always have the words to explain what is happening inside them. Instead, they show us through their behaviour. What can sometimes look like “naughty,” “defiant,” or “over the top” behaviour is often a child’s way of communicating a need, a feeling, or an experience they don’t yet know how to express.
You might notice this after school when your child falls apart over something small, refuses to listen, or becomes unusually clingy or withdrawn. These moments can feel confusing and, at times, overwhelming. However, when we shift our perspective from “What is wrong with my child?” to “What is my child trying to tell me?”, it can change how we respond in a powerful way.
One helpful way to think about this is through a child’s “capacity tank.” Throughout the day, children use up their capacity managing learning, social situations, expectations, and transitions. By the time they get home, their tank can be very low—or even empty. When this happens, even small things can feel big, and their ability to cope, listen, and regulate emotions is reduced.
It’s important to remember that children’s brains are still developing. The part of the brain responsible for reasoning, problem-solving, and impulse control is the last to fully develop.
This means that when children are overwhelmed, they are not able to “think things through” in the way we might expect. Instead, they rely on the more emotional parts of their brain, and their behaviour reflects this.
Children’s behaviour is often driven by what is happening beneath the surface. A child who is lashing out may be feeling overwhelmed, frustrated, or unsure how to cope. A child who refuses to follow instructions may be feeling anxious, disconnected, or struggling with transitions. Even silliness, avoidance, or shutting down can be signs that a child is tired, overstimulated, or in need of connection.
After a full day of holding it together, home becomes the place where those big feelings come out. While this can be challenging, it is also a sign that your child feels safe enough with you to let their guard down.
In these moments, children don’t need immediate correction as much as they need support. Before we focus on changing behaviour, it helps to first connect. Getting down to your child’s level, using a calm voice, and showing that you are there for them can help their nervous system begin to settle. You might say, “That was a big day, I’m here,” or “I can see something feels really hard right now.”
There are also simple ways you can support your child through these moments. Slowing things down, reducing the amount of language you use, and offering your calm presence can help your child feel less overwhelmed. Some children benefit from movement, a quiet space, or a familiar routine after school. Others may need closeness, reassurance, or time before they are ready to talk. Over time, you will begin to notice what helps your child feel safe and regulated.
At the same time, it is important to remember that understanding behaviour does not mean allowing all behaviour. Children need clear and consistent boundaries to feel safe. When behaviour becomes aggressive, such as hitting, kicking, or hurting others, it is important to respond calmly but firmly. You might say, “I can’t let you hit. I’m here to keep everyone safe.” In these moments, your role is to hold the boundary while also supporting your child through the feeling underneath.
Staying close, keeping your voice calm, and, where needed, gently moving your child or creating space can help maintain safety. Once your child is calmer, you can guide them towards safer and more appropriate ways of expressing their feelings.
It is also important to acknowledge that parents have a “capacity tank” too. There will be times when your tank feels empty—when you are tired, stretched, or overwhelmed yourself. In those moments, it can be much harder to respond with patience and calm. This is not a failure; it is human.
When your capacity is low, it can help to focus on the essentials: keeping everyone safe, using fewer words, and giving yourself permission to pause. Repair is always possible. Coming back to your child later with connection—“That was a hard moment for both of us”—is incredibly powerful and models emotional growth.
Supporting behaviour in this way doesn’t mean ignoring expectations. It means recognising that children do well when they can, and when they can’t, they need our guidance, patience, and support to build those skills over time.
When we begin to see behaviour as communication, we move from reacting to responding. And in that space, we create opportunities for connection, growth, and emotional development
A Small Reflection
Take a moment to think about your child over the past week. Was there a time when their behaviour felt big, confusing, or challenging?
Now, gently shift the question from - “What were they doing?” to “What might they have been feeling?”
You might also wonder - “Was their capacity tank running low in that moment?”
And perhaps just as importantly - “How full was my own tank?”
Parenting is not about getting it right every time. It’s about noticing, reflecting, and reconnecting.
