Between 3 and 6 months, communication appears as cooing, social smiling, turning towards sound and watching faces — not words. 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.

*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.*

## In short
Between 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.

## What's typical at 3–6 months
This is the pre-speech stage, where babies practise the *rhythm* of conversation long before words. By around 6 months, most babies will:

- **Coo and babble** — vowel sounds ("ahh", "ooh"), then chains like "ba-ba", and squeals or chuckles.
- **Smile and respond socially** — beaming back when you smile or talk to them.
- **Turn towards sound** — looking for your voice, a rattle or a familiar noise.
- **Take turns** — "answering" your sounds with their own, a back-and-forth that feels like chatting.
- **Watch faces and make eye contact** — gazing at your mouth and eyes as you speak.

## Gentle flags worth a clinician's eye
These are reasons to ask early — not signs of a diagnosis:

- **Very few or no sounds** — little cooing or babbling by around 6 months.
- **No social smile** — not smiling back at familiar faces.
- **Not responding to sound** — doesn't startle, quieten or turn towards your voice (this also deserves a hearing check).
- **Little eye contact or shared gaze** — rarely looking at faces during play and feeds.
- **Loss of a skill** — sounds or smiles that were there and then faded.

A simple hearing screen is often the first, reassuring step, since clear hearing underpins early communication.
