If your baby never reacts to loud sounds or never turns towards voices by around 5–6 months, ask your paediatrician for a prompt hearing check, as early review matters for later speech.","q":"How do I know if my baby can hear well?"},{"a":"Many babies have preferences and some dislike certain textures or positions, which is usually typical.

Reassuring signs include turning towards voices, following faces and objects with the eyes, and reaching for things. A gentle developmental check is wise if your baby never startles to loud sounds, does not follow faces or objects, or strongly resists most touch — this is a reason to observe early, not a diagnosis.","answer_md":"*At three to six months, every baby is busy learning to make sense of a brand-new world of light, sound and touch — gentle watching is loving parenting, not worry.*\n\n## In short\nThere is no formal \"sensory delay\" diagnosis at 3–6 months, and most differences in how babies respond to sights, sounds and touch are completely typical at this tender age. What is helpful is to notice whether your baby is turning towards sounds, looking at faces and tracking moving objects, and beginning to reach and explore. If your baby consistently does **not respond to loud sounds, does not follow your face or a toy with their eyes, or strongly resists most touch and cuddles**, a gentle developmental check is wise — not because something is wrong, but because early observation opens early opportunity.\n\n## What is typical at 3–6 months\nAt this age, the senses are coming online rapidly, and babies vary enormously. Reassuring signs of healthy sensory growth include:\n\n- **Hearing** — startling or quietening to loud sounds, turning the head or eyes towards your voice, and beginning to enjoy soothing tones.\n- **Vision** — following your face and moving objects across the midline, watching their own hands, and showing interest in faces and bright contrasts.\n- **Touch and movement** — bringing hands to mouth, accepting cuddles, beginning to reach for and grasp objects, and enjoying being held.\n\n## Gentle flags worth a clinician's eye\nThese are reasons to observe, never a diagnosis:\n\n- **Hearing** — no startle or quietening to loud sounds at all, or never turning towards voices or sounds by around 5–6 months.\n- **Vision** — eyes not following objects or faces, persistent squinting or one eye turning, eyes that don't seem to meet yours, or unusual eye movements.\n- **Touch and regulation** — distress with almost all touch, very stiff or very floppy body, or being extremely hard to soothe alongside little interest in faces or sounds.\n\nAny concern about hearing or vision specifically deserves a prompt check with your paediatrician, as early review of the ears and eyes matters for later speech and learning.\n\n## The Pinnacle way\nThis is general information, not a diagnosis — a 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 an online list.
