From 3 to 6 months most babies coo and make vowel sounds, smile and laugh back, turn towards voices, and enjoy back-and-forth 'chats' of squeals and early babble. These are gentle ranges, not a race. A relaxed check helps by 6 months if there are no sounds, no smiles, or no reaction to your voice.

*Between three and six months, your baby starts a beautiful two-way conversation — long before their first word, they are already "talking" with coos, smiles and gleeful sounds.*

## In short
From 3 to 6 months, most babies coo and make vowel-like sounds, smile and laugh in response to you, turn towards voices and sounds, and begin lively back-and-forth "chats" of squeals, gurgles and early babble. These are social-communication milestones — gentle ranges, not a race — and warm, responsive talking with your baby is exactly what nurtures them.

## What to look for from 3 to 6 months
**Listening & attention**
- Turns head or eyes towards your voice and to new sounds
- Quietens or brightens when spoken to softly
- Notices and reacts to changes in your tone

**Making sounds**
- Coos and makes long vowel-like sounds ("aah", "ooh")
- Squeals, gurgles and blows raspberries for fun
- Begins early babble, sometimes repeating sounds like "ba" or "ga" towards 6 months

**Social back-and-forth**
- Smiles and laughs during play and cuddles
- "Takes turns" — vocalising, pausing, then responding when you talk back
- Makes sounds to get your attention and shows joy at familiar faces

Remember, healthy babies reach these in their own window. A baby who is a little quieter one week and chatty the next is usually doing just fine.

## When a gentle check helps
By around 6 months, it's worth a relaxed developmental check if your baby is not making any sounds at all, does not smile or respond to your voice, doesn't react to loud sounds, or seems to have gone quiet after being more vocal. A hearing review is often the sensible first step, because early listening shapes early talking.
