Sensory Processing Differences: Signs for Nurses

A child who melts down at noise, dodges a hug, or never seems to tire of spinning may be telling you something through their senses — and an alert nurse is often the first to notice.

In short

Sensory Processing Differences describe how a child's nervous system takes in and responds to everyday sensation — sound, touch, movement, sight, taste and smell. As a nurse, watch for a child who is consistently over-responsive (distressed by ordinary noise, light, textures or touch), under-responsive (slow to react, seems not to notice sensations), or sensory-seeking (craves intense movement, pressure or input). These patterns matter most when they interfere with feeding, sleep, play, or settling for routine care — and they warrant a developmental check rather than a label at the cot-side.

Signs to watch for

Over-responsive (sensory-avoiding):

• Strong distress at everyday sounds — vacuum, hand-dryer, crowded waiting rooms.
• Resists being held, dislikes certain clothing textures, tags or seams.
• Gags or refuses foods by texture; distress at messy play, nappy changes or face-washing.
• Overwhelmed in bright or busy environments.

Under-responsive:

• Slow or muted reaction to sound, touch or even minor knocks and pain.
• Seems unaware of a soiled nappy, a runny nose, or being called.
• Appears passive, withdrawn or unusually still during examination.

Sensory-seeking:

• Constant movement — spinning, rocking, crashing, climbing without apparent caution.
• Seeks deep pressure, mouths objects beyond the usual age, touches everything.
• Difficulty sitting still or settling for sleep.

Functional red flags across all patterns: difficulty with feeding, disrupted sleep, frequent meltdowns around transitions, or trouble tolerating routine clinical care (weighing, vaccination, dressing changes). One isolated quirk is common; it is the persistent, pervasive pattern affecting daily function that should prompt onward referral.

When to refer

Note that Sensory Processing Differences are not a standalone diagnosis in WHO ICD-11 — sensory features are recognised within broader developmental and neurodevelopmental profiles. So your role is to observe, document and route, not to diagnose. Refer for a developmental and occupational-therapy assessment when sensory responses are persistent, occur across settings (home and clinic), and disrupt feeding, sleep, learning or social participation. Always rule out hearing and vision concerns first, and flag any regression or loss of skills for prompt paediatric review.

The Pinnacle way

AbilityScore® is part of Pinnacle’s developmental assessment. Diagnosis, where needed, requires an appropriately qualified healthcare professional — never from a checklist or screen alone. Your structured observations are invaluable: they help a clinician build a precise sensory and developmental profile and shape support through occupational therapy.
