Why Does My Child Fall Apart at Home?

“They’re fine at kindy. They seem to manage well at school. But as soon as we get home, everything falls apart.”

If this sounds familiar, you’re not alone!

For many families, the contrast between how their tamariki manage in the outside world and how they behave at home can be confusing — and exhausting. You might find yourself wondering, “Why can they do it there but not here?” or even, “What am I doing wrong?”

The answer may be more about capacity than behaviour.

A day can be a lot

For neurodivergent children in particular, everyday experiences can require significant effort. There is noise and sensory input to process, social interactions to navigate, transitions between activities, instructions to follow, uncertainty to tolerate and emotions to manage.

At kindy, kōhanga or kura, your child may be using a great deal of their available energy to participate and navigate their environment.

By the time they get home, there's just less capacity left.

This can look like a meltdown, irritability, refusal, tears, withdrawal, or becoming overwhelmed by something that seems small.

It doesn’t necessarily mean your child is choosing to behave differently at home - but they have reached the edge of what they can manage in that moment.

The “empty cup”

One way to picture this is through the “empty cup” metaphor. Throughout the day, a child’s cup can gradually be used up by the many things they are navigating — sensory input, social interaction, transitions, communication, learning, uncertainty and the effort involved in regulating their emotions and behaviour.

For some children, the sensory and developmental demands of a busy day may draw heavily on that available capacity. By the time they get home, their “cup” may be close to empty.

This can help explain why te tamaiti who managed at preschool or school may struggle with seemingly small things at home.

They may simply have less capacity available.

When the cup is empty, the most supportive thing we can do is help create the conditions for the cup to refill — through connection, food, movement, quiet, sensory support, rest and predictable routines.

Making space

When we understand what may be sitting underneath a difficult moment, we can respond with greater curiosity and compassion.

Your child doesn’t need you to have all the answers. They need opportunities to feel understood, supported and connected as they develop their capacity to navigate the world around them.

Sometimes that might mean slowing down, reducing the demands, offering connection, or simply being alongside them while their cup begins to refill.

Research shows that small moments of connection can create meaningful opportunities for growth. By noticing what your child is communicating and responding to their individual needs, we can help create everyday experiences where they feel safe to participate, explore and be themselves.

Because understanding the why behind a behaviour is the first step towards finding a new pathway forward.
