Mapping a Child's Sensory World

How Occupational Therapists explore the way children experience their bodies and surroundings

Every child experiences the world through their senses, including sound, vision, touch, taste, smell, movement, and body position. But children do not all process sensory information in the same way.

A sound one child barely notices may overwhelm another. One child may avoid messy hands, while another seeks opportunities to touch, squeeze, climb, jump, or crash. An occupational therapist (OT) can explore these patterns and how they affect everyday activities.

What Is Sensory Mapping?

Sensory mapping helps an OT identify patterns in a child's responses to sensory input. Hypersensitivity means the child may notice or react strongly to sensory input that others tolerate. Hyposensitivity means the child may notice sensory input less readily and may need stronger or more frequent input to register it.

A sensory map provides a quick visual snapshot of the child's sensory profile. It helps parents, caregivers, educators, and other team members see, at a glance, where the child may be hypersensitive, hyposensitive, or sensory seeking. This shared understanding can help the team recognize sensory needs and use appropriate strategies at home, school, daycare, or in the community.

For example, a child may dislike having their face or hair touched but enjoy firm pressure through their arms and legs. Another may be sensitive to sounds while seeking movement through jumping, spinning, or climbing. A sensory body map helps the OT communicate these differences clearly.

Looking Beyond the Five Senses

We commonly think about five senses: touch, hearing, vision, taste, and smell. OTs also consider sensory systems related to body awareness and movement.

The vestibular system provides information about movement and balance. The proprioceptive system receives information from muscles and joints, helping us understand body position and force. Interoception involves noticing internal sensations such as hunger, thirst, fatigue, temperature, or the need to use the bathroom.

Together, these systems influence movement, play, learning, self-care, and interaction with the environment.

What Might an OT Observe?

An OT may notice that a child responds strongly to certain sensations, responds less than expected, or actively seeks sensory input. A child might cover their ears, resist grooming, avoid certain textures, seek firm pressure, or frequently jump and crash into things.

The OT considers the overall pattern rather than one behaviour in isolation. A child can also respond differently across sensory systems. For example, they may be sensitive to sound and touch while simultaneously seeking movement or deep-pressure input.

A Visual Example of Sensory Mapping

An accompanying illustration provides an example of what a sensory map may look like. It demonstrates how an OT may visually document sensory responses across different areas of the body and sensory systems.

For example, the map may identify tactile hypersensitivity to light touch and cold at the scalp or hands, tactile hypersensitivity to light touch at the face, hyposensitivity to taste at the mouth, vestibular hyposensitivity to angular movement, or hyposensitivity within the proprioceptive system.

The illustration is an educational example only. It does not represent a complete assessment or the sensory profile of a specific child. Every child's sensory profile is unique.

Why Does the OT Map These Responses?

The goal is not simply to label responses. The OT aims to understand how sensory experiences may affect dressing, bathing, eating, sleeping, play, school participation, transitions, social interaction, and family routines.

Sensory mapping helps the OT identify patterns that may contribute to challenges in these activities.

From Sensory Mapping to Everyday Strategies

Sensory mapping is only one part of the occupational therapy process. Findings are considered alongside the child's abilities, activities, environment, routines, and individual needs.

Based on the assessment, an OT may recommend movement or proprioceptive activities, environmental modifications, routine changes, gradual exposure, regulation strategies, or individualized home activities. The OT can monitor the child's response and adjust the approach as needed.

There is no single sensory activity that works for every child. A strategy that helps one child may be uncomfortable or overly stimulating for another. This is why individualized assessment is important.

Seeing the Whole Child

Sensory processing is only one part of a child's development. Communication, attention, emotions, motor abilities, sleep, relationships, and the environment can also influence participation.

For this reason, occupational therapists consider the child, the activity, and the environment together. Mapping a child's sensory world can help us better understand everyday experiences and identify meaningful ways to support comfort, regulation, independence, and participation.
