These are the quiet, joyful signs of a sensory system finding its feet.*\n\n## In short\nBy three to six months, most babies track moving objects smoothly with their eyes, turn towards sounds and your voice, reach for and grasp objects they see, and explore textures with hands and mouth. These sensory milestones show that vision, hearing and touch are working together beautifully. Every baby has their own rhythm, so think of these as a happy range, not a strict timetable.\n\n## Sensory milestones to enjoy and notice\n**Vision (seeing)**\n- Follows a moving toy or your face smoothly from side to side\n- Reaches accurately for objects they can see — hand-eye coordination is blooming\n- Notices small objects and watches their own hands with interest\n- Recognises familiar faces across the room and smiles\n\n**Hearing (sound)**\n- Turns head towards sounds, voices and music\n- Quietens, smiles or gets excited when they hear your voice\n- Startles or reacts to sudden loud sounds\n- Begins to enjoy babbling back when you talk to them\n\n**Touch and movement (tactile and body awareness)**\n- Brings hands and toys to the mouth to explore — this is healthy, not a worry\n- Enjoys different textures and being held, rocked and cuddled\n- Holds head steady and pushes up on arms during tummy time\n- Responds with pleasure to gentle touch and play\n\n## A gentle word on range\nMilestones arrive within a window, not on a fixed date. A baby born early may reach these a little later — that's expected. What's worth a friendly developmental check is if, by around six months, your baby does not turn to sounds or voices, doesn't follow objects with their eyes, doesn't reach for toys, or seems unusually stiff or floppy. These are reasons to chat with your paediatrician, not reasons to panic.\n\n## The Pinnacle way\nA clinical [AbilityScore®](/ask/what-is-the-abilityscore-and-how-is-it-calculated) and any diagnosis are formed only at a Pinnacle Blooms Network centre under qualified clinician care — never from a checklist at home.
