Education
A sensory diet isn't a food plan. It's a schedule of movement and sensory activities built for a specific child's nervous system, and when it works, it changes everything.
The term 'sensory diet' was coined by occupational therapist Patricia Wilbarger in the 1980s, and despite being one of the most useful concepts in inclusive education, it remains one of the least understood. I have sat in school meetings where the OT recommendation said 'implement sensory diet as per attached schedule' and watched every adult in the room nod and say nothing, because none of them wanted to admit they didn't know what a sensory diet was.
So let's be plain about it: a sensory diet is a personalised schedule of sensory and movement activities designed to help a child's nervous system reach and maintain an optimal state for learning and participation. It has nothing to do with food. It is called a diet in the sense that it is a curated, regular input, nourishment for the nervous system rather than the body.
Why some children need one
Most people self-regulate sensory input without thinking about it. You stand up and stretch when you've been sitting too long. You seek quiet when you're overstimulated. You bounce your leg under the table during a long meeting. These are all sensory regulation behaviours, they are your nervous system managing its own input.
Children with sensory processing differences, which includes many autistic children, children with ADHD, and children with sensory processing disorder, often cannot self-regulate efficiently. Their nervous system may seek too much input (sensory seeking) or be overwhelmed by ordinary levels of it (sensory avoiding), sometimes both in different sensory channels. A sensory diet provides the input that the nervous system is seeking, or reduces input that is creating overload, on a proactive schedule, before the child reaches the point of dysregulation.
“The goal of a sensory diet is to get ahead of dysregulation, not to respond to it. By the time the behaviour appears, you've missed the window.”
The two main types of sensory input
When building or implementing a sensory diet, it helps to understand the difference between alerting and organising/calming inputs. Alerting inputs increase arousal, they are useful for a child who is under-aroused, flat, or checked out. Calming and organising inputs reduce arousal, they are useful for a child who is over-stimulated, anxious, or escalating.
- Alerting inputs: movement breaks, jumping, bouncing, cold water on the face, bright light, crunchy foods, fast music
- Heavy work (proprioceptive): wall push-ups, carrying books or boxes, pushing a trolley, wearing a weighted vest, this category is organising and regulating for most children
- Calming inputs: slow rocking, deep pressure (like a weighted lap pad), quiet environments, warm water, rhythmic movement, slow breathing
- Oral motor: chewing (gum, crunchy snacks, a chew tool) provides strong proprioceptive input and is highly organising for many children
What a sensory diet looks like in a school day
A school-based sensory diet is not a long list of complicated activities. At its most practical, it is a scheduled set of inputs, usually built around natural transition points in the school day, designed to keep the child's nervous system in a regulated state.
- Arrival: five minutes of heavy work before sitting, carrying something, doing wall push-ups in the corridor, organising materials with physical effort
- Before a demanding learning block: a short movement break, jumping jacks, bear walks, a brief walk to the office and back with a message to deliver
- Mid-morning: access to a fidget tool at the desk, a wobble cushion, or a standing option, continuous low-level proprioceptive input
- After lunch (often the highest dysregulation risk): a structured, active reintegration activity before returning to seated work
- Before challenging transitions: a brief calming input, slow breathing, a squeeze of a stress ball, a moment in a quiet space
Common examples of sensory diet tools for school
- Fidget tools at the desk, putty, a tangle toy, a textured disc, for children who need low-level tactile or proprioceptive input to maintain focus
- Wobble cushions or move-and-sit discs, provide vestibular and proprioceptive input without leaving the seat
- Ear defenders or noise-reducing earplugs, allow the child to control auditory input during independent work
- Chewy tools or gum (where school policy permits), strong oral motor input that is calming and organising
- Weighted lap pads, gentle deep pressure across the legs that many children find settling
- A designated movement break role, being the person who collects the lunch orders, takes the note to the office, or hands out materials provides movement with social legitimacy
Getting a sensory diet developed
A proper sensory diet is developed by an occupational therapist following a sensory assessment, most commonly the Sensory Profile or a similar tool. If your child's NDIS plan includes OT support, or if the school has access to an OT through allied health programs, this is one of the highest-value uses of that support. Ask specifically for a classroom-based sensory diet with implementation support for the classroom teacher.
In the meantime, the principles above are a reasonable starting point. Observe when the child is most regulated and what preceded it. Observe when they are most dysregulated and what preceded that. You will quickly start to see the pattern that the formal assessment will confirm. You don't need to wait for the assessment to start reducing unnecessary sensory load and building in sensory breaks. You just need to start noticing.
