As parents, we often notice behaviour first.
A child may be constantly moving, crashing into furniture, refusing to wear certain clothes, covering their ears, chewing on their sleeves, struggling to sit at the dinner table, or collapsing into an explosive meltdown after a busy day at school. It is easy to interpret these moments as “not listening,” “being difficult,” “seeking attention,” or “refusing to cooperate.”
Sometimes, however, behaviour is telling us something critical about what is happening inside a child’s body. By bridging Ayres Sensory Integration® with Dr. Mona Delahooke’s neurosequential, brain-body framework, we can shift our perspective from “How do I stop this behaviour?” to “What might my child’s nervous system be telling me?”
What Is Sensory Integration?
Every moment of the day, our brain receives a constant stream of information from our body and the surrounding environment. While we are familiar with vision, hearing, touch, taste, and smell, other internal systems are equally vital:
- The Vestibular System: Provides information about movement, balance, and where our head is in space.
- The Proprioceptive System: Receives feedback from muscles and joints, telling us where our body parts are and how much physical force we are using.
- Internal Sensations (Interoception): Signals internal bodily states such as hunger, thirst, fatigue, or a full bladder.
Ayres Sensory Integration® (ASI) describes how the nervous system receives, interprets, and organizes these sensory signals so children can produce effective adaptive responses and participate in daily life.
While most people process these inputs automatically, some children experience sensory information as too intense, too dull, or difficult to organize. When this happens, it directly shapes what we observe as behaviour.
The Same Environment, Different Nervous Systems
Imagine walking into a busy birthday party: music playing, children shouting, balloons popping, strong food smells, and people brushing past one another.
- Child A runs straight into the chaos, energized by the activity.
- Child B stays glued to a parent’s side, covering their ears.
- Child C immediately begins running, jumping, and crashing into other kids.
- Child D copes well for an hour, but experiences an explosive meltdown the moment they return home.
They experienced the exact same room, but their nervous systems processed the environment entirely differently.
Mapping Sensory Needs to Observable Behaviour
| Sensory System / Need | What You Might See at Home | What Is Happening Below the Surface |
| Auditory Sensitivity | Covering ears, leaving noisy rooms, distress during school assemblies, irritability in crowds. | The brain registers sound inputs at heightened intensity, triggering an involuntary stress response. |
| Movement / Body Input Seeking | Jumping off furniture, wrestling, crashing into cushions, running instead of walking, inability to stay seated. | The nervous system receives too little movement input and craves vestibular/proprioceptive feedback to stay organized. |
| Tactile Sensitivity | Resisting certain clothing, extreme distress over seams/labels, avoiding messy play, hating hair brushing or nail cutting. | Touch receptors send alarm signals to the brain, making neutral tactile inputs feel threatening or physically uncomfortable. |
| Difficulty Registering Body Input | Pressing too hard with pencils, accidentally bumping into others, squeezing too tightly, dropping objects frequently. | The proprioceptive system has difficulty gauging force, spatial boundaries, speed, and body placement in relation to surroundings. |
Looking Underneath the Behaviour:
Pediatric psychologist Dr. Mona Delahooke urges adults to view challenging behavior in the context of a child’s physiological state rather than assuming every action is intentional. A behaviour is often a child’s attempt to cope with overwhelming sensory, emotional, or physiological demands:
- Movement in Class: A child pacing or squirming may need movement input to stay awake and regulated—not simply needing to “try harder to sit.”
- Shopping Centre Refusal: A child refusing to walk into a store may be overwhelmed by fluorescent lights, noise, and crowds—rather than being deliberately oppositional.
- Pushing in Line: A child pushing others may struggle to judge personal space or physical force—though they still need support to keep peers safe.
- After-School Meltdowns: A child collapsing at home has often spent hours masking and managing a demanding sensory environment until reaching their absolute capacity.
Looking beneath behaviour does not mean removing boundaries. It means understanding why something is happening so we can select an effective response.
Regulation Comes Before Higher-Level Skills
When a child’s nervous system is dysregulated or overloaded, the prefrontal cortex—the region of the brain responsible for listening, logic, communication, and frustration tolerance, goes offline.
Repeating phrases like “Use your words,” “Calm down,” or “Listen to me” will not work when a child is in a state of sensory stress. Supporting regulation must come first:
- Reduce Sensory Load: Dim lighting, quiet the room, or step outside.
- Minimize Verbal Demands: Speak in fewer, calmer words.
- Offer Grounding Input: Allow safe movement or offer firm, supportive physical presence.
- Co-Regulate: Remain emotionally available while the child’s nervous system settles.
Becoming a “Sensory Detective”
Supporting sensory needs isn’t about buying specialized gear or giving every child a fidget toy. Sensory strategies must be individualized. Start by observing your child and asking:
- Context: What happened right before the behaviour escalated? Was the environment noisy, crowded, or unpredictable?
- Sensory Triggers: Which textures, sounds, clothes, or visual settings consistently cause distress?
- Sensory Seeking: What inputs does my child actively seek out (jumping, squeezing, chewing, spinning)?
- State of Being: Are things harder when they are tired, hungry, or unwell?
- Organizing Inputs: What actually helps their body settle (firm pressure, quiet spaces, going outside, sitting somewhere snug)?
Shift your internal question from “Why are you behaving like this?” to “What is making this hard for you right now?”
When to Consult an Occupational Therapist
Sensory differences are a normal part of human variation. Enjoying movement or disliking loud sounds does not mean a child requires therapy.
An Occupational Therapy assessment is recommended when sensory and motor differences consistently interfere with a child’s ability to participate in essential daily activities—such as dressing, eating, sleeping, playing, learning, or attending school.
Note: Home strategies differ from formal clinical intervention. Occupational Therapy using Ayres Sensory Integration® is an assessment-driven therapy delivered under specialized fidelity criteria.
The goal is never to force a child to tolerate every sensory trigger or act like everyone else. It is to understand how their individual nervous system functions so they can navigate daily life with comfort, confidence, and success.
