The ‘Big Sensory Cup’ Theory: Why Some Kids Just Can’t Sit Still

Why does my child need so much sensory input? Some children have what we call a ‘Big Sensory Cup.’ This means their nervous system requires a lot of movement, touch, or sound to feel ‘full’ and regulated. Until that cup is filled with sensory input, they may struggle to sit still, focus, or stay calm. 

If you’ve ever felt like your child has a ‘motor that never stops,’ you aren’t alone, once you understood the Big Cup vs. Small Cup theory, everything changes. 

Is your child a ‘Big Cup’ or a ‘Small Cup’? 

Think of your child’s sensory system like a literal cup. 

  • The Small Cup (Sensory Sensitive): For children with a ‘small cup’, it only takes a tiny bit of noise, bright light, or a scratchy shirt tag to fill it up. When the cup overflows, they might have a meltdown or show behaviours like wanting to hide away. 
  • The Big Cup (Sensory Seeker): For children with a ‘big cup’, hey need to move, crash, spin, and touch everything just to get enough ‘fuel’ to feel their body. If their cup is empty, they go looking for input – often by wiggling in their chair or tapping their pencil. 

 

Finding the Perfect Balance at Share My Ability 

At Share My Ability, our specialised facilities in Penrith are designed with both cups in mind. For the ‘Big Cup’ sensory seekers, our inclusive indoor play centre offers the space to crash, climb, and swing – safely filling that cup to the brim in a way that’s hard to do in a living room. For our ‘Small Cup’ more sensory sensitive friends, we offer low-sensory environments with our quiet Zen Zone where children can regulate at their own pace without the fear of an ‘overflow’. For parents and carers of children with all types of sensory needs, you can feel at ease knowing there’s no need to worry about potential meltdowns or moments of overwhelm. Our friendly and experienced staff are understanding and well-equipped to support all reactions and expressions in a calm, supportive way. Our goal at Share My Ability is to create a space where every child’s sensory needs are understood and celebrated!
