These are typical [sensory](/sensory) milestones — every baby blooms on their own gentle timeline, so think of these as a guide, not a deadline.\n\n## What to look for\n**Vision (seeing)**\n- Follows a moving toy or face smoothly from side to side\n- Watches your face closely and shows interest in bright colours and patterns\n- Reaches towards objects within sight by around 4–5 months\n\n**Hearing (listening)**\n- Turns head towards your voice or a soft sound\n- Calms, startles or brightens in response to familiar sounds\n- Enjoys back-and-forth cooing and noticing musical toys\n\n**Touch & mouthing (exploring)**\n- Brings hands together and to the mouth to explore\n- Grasps and mouths toys to learn their texture\n- Settles with gentle holding and skin-to-skin contact\n\n## The science\nIn the WHO ICF framework, these fall under *Sensory functions (b2)* — the building blocks of how a baby receives and makes sense of sight, sound and touch. In these months the brain is rapidly wiring vision, hearing and tactile pathways together, which is why reaching towards a seen object is such a meaningful step: it shows the senses are teaming up.\n\n## The Pinnacle way\nDevelopmental measurement supports care planning; diagnosis requires an appropriately qualified healthcare professional. under qualified clinician care — never from an online list.
