YOUR QUESTION. A CLEARER NEXT STEP.
Sensory milestones to check at routine visits
At routine visits, screen sensory function across vision, hearing and sensory processing — mapped to WHO ICF b2. Confirm newborn screens, track age-expected sensory-responsive behaviours at each contact, and refer promptly on any failed screen, loss of responsiveness, or cross-setting sensory reactivity.

Sensory function quietly underpins every other developmental domain — and the routine visit is where atypical patterns first surface.
In short
At routine well-child visits, screen sensory function across vision, hearing, and sensory processing/integration, mapped to WHO ICF seeing and related functions and hearing and vestibular functions (b2). Confirm newborn hearing and vision screens were completed and acted upon, then track age-expected sensory-responsive behaviours at each contact — and refer promptly when any screen fails or behavioural milestones are absent.
Sensory milestones to check by contact point
Newborn–3 months
- Universal newborn hearing screen (OAE/AABR) completed and passed; document any refer result
- Red reflex present and symmetrical; fixes and follows a face briefly
- Startle/quietens to sound; calms to caregiver voice and gentle holding
4–9 months
- Turns head to localise sound by ~6 months; vocal turn-taking emerging
- Tracks objects across midline; reaches for and mouths objects (tactile/oral exploration)
- Tolerates varied textures during weaning; accepts handling and position changes
12–18 months
- Responds consistently to name and quiet speech; follows simple sound cues
- Points to share interest (integrates vision with social attention)
- No marked over- or under-reaction to everyday sound, light, touch or movement
2–4 years
- Tolerates grooming, clothing textures, and a reasonable range of food textures
- Modulates activity level; settles after vestibular/proprioceptive play
- No persistent sensory-seeking or sensory-avoiding pattern that disrupts routines
Always act on
- Any failed or incomplete hearing or vision screen — refer for audiology/ophthalmology, do not re-test informally and wait
- Loss of previously present responsiveness to sound, or new visual inattention
- Parental report of extreme, cross-setting sensory reactivity affecting feeding, sleep or participation
When to refer
An isolated sensory-processing quirk in an otherwise on-track child can be monitored. Escalate when a sensory screen fails, when sensory-reactivity patterns persist across home and clinic, or when sensory concerns coexist with communication, motor or feeding delay — these warrant onward assessment rather than watchful waiting. Hearing and vision failures are time-critical for downstream language and learning and merit same-week referral.
The Pinnacle way
A clinical AbilityScore® and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care — it is a clinician-administered structured assessment that complements, not replaces, your examination and gives an objective multi-domain baseline to track change. Pinnacle supports onward sensory integration therapy and broader developmental review via the main pathway. Backed by 2.5 billion+ data points and 25 million+ therapy sessions across 70+ centres.
Trusted sources
Aligned with the WHO International Classification of Functioning, Disability and Health (ICF) sensory functions domain (b2), and consistent with AAP and CDC developmental-surveillance guidance on routine hearing and vision screening.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Escalate to same-week referral on any failed or incomplete hearing/vision screen, or loss of previously present responsiveness to sound. When sensory reactivity coexists with communication, motor or feeding delay, refer for multidisciplinary assessment rather than monitoring.
In everyday life
High-yield consult check: confirm the newborn hearing screen result on file, test sound localisation and name response, observe red reflex and visual tracking, and ask one open question about food textures and reactions to noise or touch.

Bring your questions to a first visitQuestions families ask
Which sensory screens are time-critical at routine visits?
Newborn hearing screening and vision (red reflex, fixing and following) are the most time-critical, because failures directly affect downstream language and learning. A failed or incomplete screen warrants prompt audiology or ophthalmology referral rather than informal re-testing and delay.
How do I distinguish a normal sensory quirk from a concern?
An isolated sensory preference in an otherwise on-track child can be monitored. Concern is raised when over- or under-reactivity to sound, light, touch, movement or food texture is marked, persistent across home and clinic, and disrupts feeding, sleep or daily participation — particularly alongside other developmental delays.
Where does sensory processing sit in WHO classification?
Sensory functions map to the WHO ICF body-functions chapter b2, covering seeing and related functions and hearing and vestibular functions, alongside additional sensory functions. The ICF frames these in terms of functioning and participation rather than diagnosis alone.
