How can I tell if my child has sensory processing difficulties?

Wondering about a possible sensory processing difficulty in your child often starts with everyday moments: many parents notice their child “overreacts” to noise, refuses certain clothes, or, conversely, seems insensitive to pain and always on the move. These behaviors may relate to sensory processing—how the brain receives, filters, and organizes sensory information—rather than simple “tantrums.” This article helps you notice possible signs linked to hypersensitivity, hyposensitivity, or sensation seeking. It is not a substitute for medical or allied health advice: only a professional can make a diagnosis and recommend appropriate care.

Sensory processing and your child’s profile

Sensory processing involves sight, hearing, touch, taste, and smell, but also proprioception (awareness of the body in space) and the vestibular system (balance, movement). In children, these systems mature gradually; wide differences from one child to another are normal.

In clinical literature and occupational therapy, Winnie Dunn’s model often describes profiles: a tendency to avoid or seek certain sensations, with lower thresholds (more reactivity) or higher ones (less reactivity). This framework helps structure day-to-day observation; it is not a diagnosis by itself. Public health institutions stress the importance of a holistic developmental assessment when difficulties persist—for example the child development resources from the U.S. CDC, useful as educational guidance even outside the United States.

Hypersensitivity in children: when senses feel “too much”

A hypersensitive child experiences certain stimuli as intense or unpleasant sooner than average. Signs vary by sensory modality.

Hearing and vision

Refusal of noisy places (cafeteria, parties, vacuum cleaner), hands over ears, difficulty concentrating as soon as there is background noise. Visually: discomfort with bright lights or visual clutter (stores, very dense displays).

Touch and clothing

Collar tags, seams, or “scratchy” fabrics can cause significant discomfort. The child may want the same clothes every day or refuse tight shoes, and that may not be explained by opposition alone.

Taste and smell

Restricted eating (textures, mixing), nausea with certain smells (cleaning products, perfumes) more marked than in peers.

These signs can coexist with other profiles or conditions; they mainly invite you to note the context in which they appear and how often they disrupt family, school, or social life. In France, assessing difficulties with activities of daily living (meals, dressing, school) follows a care pathway: the Haute Autorité de Santé publishes good-practice recommendations on child follow-up and referral to appropriate professionals when developmental disorders are suspected—including occupational therapists when daily tasks are affected.

Hyposensitivity and sensation seeking

Conversely, a hyposensitive child may seem less responsive to stimuli that grab others’ attention: not turning when called (when hearing loss is ruled out), seeming indifferent to a small cut or cold temperature.

Sensation seeking often shows up as a greater need for movement, pressure, or intensity: repeated jumping, “playful” bumping, chewing on objects or clothes, needing very firm hugs. It is not always hyperactivity: sometimes the child is looking for a level of sensory input that helps them feel “regulated.”

It helps to separate contextual behavior (excitement, fatigue) from a stable pattern over several weeks and in several settings (home, school, grandparents’ house). Research on sensory processing in children appears in peer-reviewed journals; for example, open-access summaries on PubMed Central show the topic is studied seriously, while diagnostic criteria remain debated across classification systems.

Summary table: observation cues

This table helps organize your observations; it is not enough to conclude there is a “sensory disorder” in the strict medical sense, because many signs appear in other situations (anxiety, developmental conditions, fatigue, etc.).

“Sensory diagnosis”: what parents should know

The phrase sensory diagnosis is common in everyday language; official health frameworks vary. In the United States, some clinicians discuss sensory processing–related difficulties within multidisciplinary assessment; in France, practice more often relies on a global evaluation (physician, psychologist, occupational therapist, speech-language pathologist as needed). National references on neurodevelopment, such as the Inserm autism overview (where unusual sensory reactions are often mentioned among possible features), emphasize profile diversity and the importance of a structured care pathway when social, communication, or sensory difficulties persist together.

In short: noticing signs at home is a useful first step; making a diagnosis belongs to professionals. If behaviors limit school, sleep, meals, or relationships, an appointment with your primary care physician or referring health professional can guide you to the right specialties.

Everyday strategies without guilt

A few simple principles—not a full therapy guide:

• Anticipate difficult settings (age-appropriate noise-canceling headphones, outings at quieter times when possible).
• Offer alternatives to sensation seeking (weighted cushion, regular movement breaks, proprioceptively rich activities with supervision).
• Name what the child experiences (“the noises feel very loud to you”) rather than dismissing the discomfort.
• Consistency among adults on safety rules (movement yes, but no danger to self or others).

These ideas do not replace individualized care when difficulties are marked.

Go further

If you want a structured view of your child’s sensory processing in daily life—with questions about concrete habits rather than quick labels—you can start the questionnaire on Sensorikid: a guided conversational flow, inspired by Winnie Dunn’s model, to identify action ideas suited to your context. The service works without an account and without storing your personal data on our servers; answers stay on your device. The full version is €5, deliberately affordable compared with an in-depth in-clinic assessment.
