The Science of It
What Your Child's Body Is Asking For
Sensory needs, sensory diets and the science of what actually regulates a neurodivergent nervous system.
April 2026 · 5 min read
Your child wants to crash into the sofa. Again. They want to be squeezed. They want to spin, to jump, to carry things that are too heavy for them, to chew on the collar of their shirt.
This is not random. This is not naughtiness. This is a nervous system asking, in the only language available to it, for exactly what it needs.
The body as a regulatory system
The nervous system regulates itself partly through sensory input. Specific types of sensory experience – particularly proprioception (the sense of the body's position, through muscles and joints) and vestibular input (movement and balance) – are directly regulatory. They activate the parasympathetic nervous system and reduce arousal.
This is why swinging calms most children. Why a tight hug helps. Why jumping on a trampoline before homework makes concentration easier rather than harder. These are not indulgences – they are neurological inputs that directly improve regulatory capacity.
Neurodivergent children often need more of these inputs than neurotypical children, or different inputs, or both. Their sensory seeking is the nervous system doing its own occupational therapy.
What a sensory diet is
A sensory diet – a term coined by occupational therapist Patricia Wilbarger – is a personalised programme of sensory activities distributed through the day to meet a child's specific regulatory needs. It is not about food. It is about giving the nervous system consistent access to the inputs it needs to stay regulated.
A morning movement break before school. Heavy work (carrying, pushing, climbing) before a demanding transition. A proprioceptive activity after school during the decompression window. A sensory wind-down before bed.
Starting without an assessment
A formal sensory integration assessment from an occupational therapist is the ideal starting point for a personalised sensory diet. But you can begin observing your child's sensory patterns immediately, without professional support.
Notice what they seek. Notice what they avoid. Notice when sensory input helps them and when it tips them over. Notice the times of day when their seeking behavior increases – often a sign that regulatory reserves are running low.
Your observations are data. And data is how you start to understand what your child's body is asking for.
