A plain-language guide to all 8 sensory systems, what sensory seeking and avoiding look like, how to tell whether a strategy is calming or alerting — and a tracker to build a picture of your child's unique sensory needs.
Your child's brain receives information from 8 different sensory channels at once — all day, every day. Understanding each one is the first step to understanding your child.
The sense of touch — skin receptors that detect pressure, temperature, texture, and pain.
Inputs: Light touch (feathers, tags in clothing), Deep pressure (hugs, weighted blankets), Texture (food, surfaces, fabrics)
The sense of movement and gravity — detected in the inner ear. Tells the brain where the body is in space and whether it's moving.
Inputs: Swinging, spinning, rocking, Head position changes, Speed of movement
The 'hidden sense' — receptors in muscles and joints that tell the brain where body parts are without looking. Often called the body's GPS.
Inputs: Heavy work (pushing, pulling, carrying), Joint compression (jumping, stomping), Deep pressure (tight hugs, weighted objects)
The sense of hearing — not just what sounds are present, but how the brain processes and filters them. Some children hear everything equally and can't filter background noise.
Inputs: Volume (loud vs quiet), Pitch (high vs low sounds), Background noise filtering
The sense of sight — how the brain processes visual information. Includes sensitivity to light, movement, colour, and visual clutter.
Inputs: Light intensity (bright vs dim), Colour and contrast, Visual clutter (busy environments)
The sense of taste — beyond sweet/salty/sour/bitter, this system also processes texture, temperature, and the oral experience of eating.
Inputs: Flavour intensity (strong vs mild), Texture of food (smooth, crunchy, mixed), Temperature of food or drinks
The sense of smell — one of the most powerful sensory systems because it connects directly to the limbic system (emotions and memory). Smell can instantly calm or overwhelm.
Inputs: Intensity of scents (strong vs subtle), Pleasant vs unpleasant odour response, Smell memory and association
The sense of what's happening inside the body — hunger, thirst, temperature, heart rate, bladder fullness, pain, and emotional feelings as physical sensations.
Inputs: Hunger and thirst signals, Fatigue and energy levels, Emotional feelings in the body
Children who have difficulty processing sensory input typically respond in one of two ways — or sometimes both, in different systems. Neither is a behaviour problem. Both are the nervous system communicating what it needs.
The nervous system is under-responsive — it needs more input than typical to register what's happening. The child seeks extra input to feel regulated.
What it looks like:
The nervous system is over-responsive — it registers input more intensely than typical. The child avoids input that feels overwhelming or painful.
What it looks like:
Sensory strategies don't work the same way for every child. The same activity can calm one child and wind another one up. Here's how to think about the three effects:
Brings an over-aroused or dysregulated nervous system down. Slows breathing, reduces movement, decreases intensity. Great for transitions, bedtime, or after a hard moment.
Brings a disorganised nervous system into a ready-to-learn state. Not too calm, not too alert — the "just right" zone. Ideal before school, homework, or tasks that require focus.
Brings an under-aroused or sleepy nervous system up. Increases energy, attention, and arousal. Great for mornings, after a long car trip, or when energy is low before a task.
One strategy is listed per sensory system with its typical effect. Every child is different — always watch your child's actual response, not just the label.
Fill this in over 2–4 weeks of observation. Circle or colour in the boxes to show your child's typical pattern for each sensory system.
Craves input from this system — always wants more. Colour in the teal boxes.
No strong pattern — some seeking, some avoiding, or varies by situation. Colour in the green boxes.
Overwhelmed by input from this system — tries to escape or avoid it. Colour in the terracotta boxes.
Use 1, 2, or 3 boxes to show how strong the pattern is (1 = mild, 3 = very strong). Some systems may be left blank if no clear pattern has emerged yet.
Use this log to notice patterns over time. You don't need to fill in every row every day — even 2–3 observations per week builds a useful picture.
When did this happen?
What was my child doing or responding to?
What did I try to help?
Did it calm, alert, or organise? Did it help?
