Seek a developmental check if your baby rarely makes sounds, doesn't smile back, doesn't respond to voices or sound, or makes little eye contact by around 6 months. A hearing screen is often a reassuring first step. None of this is a diagnosis — it means early, gentle review is wise, because support works best now.","answer_md":"*At three to six months, your baby is just beginning their conversation with the world — coos, gazes and gurgles are the first words of a language all their own.*\n\n## In short\nBetween 3 and 6 months, communication shows up as cooing, smiling back at you, turning towards voices and watching faces — not in words yet. Gentle reasons to seek a developmental check include a baby who **rarely makes sounds, doesn't smile socially, doesn't turn towards voices or sounds, or makes little eye contact** by around 6 months. None of this is a diagnosis — it simply means a clinician's warm, early look is wise, because support at this age works beautifully.\n\n## What's typical at 3–6 months\nThis is the pre-speech stage, where babies practise the *rhythm* of conversation long before words. By around 6 months, most babies will:\n\n- **Coo and babble** — vowel sounds (\"ahh\", \"ooh\"), then chains like \"ba-ba\", and squeals or chuckles.\n- **Smile and respond socially** — beaming back when you smile or talk to them.\n- **Turn towards sound** — looking for your voice, a rattle or a familiar noise.\n- **Take turns** — \"answering\" your sounds with their own, a back-and-forth that feels like chatting.\n- **Watch faces and make eye contact** — gazing at your mouth and eyes as you speak.\n\n## Gentle flags worth a clinician's eye\nThese are reasons to ask early — not signs of a diagnosis:\n\n- **Very few or no sounds** — little cooing or babbling by around 6 months.\n- **No social smile** — not smiling back at familiar faces.\n- **Not responding to sound** — doesn't startle, quieten or turn towards your voice (this also deserves a hearing check).\n- **Little eye contact or shared gaze** — rarely looking at faces during play and feeds.\n- **Loss of a skill** — sounds or smiles that were there and then faded.\n\nA simple hearing screen is often the first, reassuring step, since clear hearing underpins early communication.\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 an online list.
