Communication Milestones for a 6-to-9-Month-Old

Somewhere between six and nine months, your baby's babble starts to sound like a real conversation — full of feeling, even before the first word arrives.

In short

Between 6 and 9 months, most babies babble with repeated sounds like "bababa" and "mamama", turn towards your voice, respond to their name, enjoy back-and-forth sound games, and use cries, coos and gestures to tell you what they want. These are the building blocks of speech — what matters most is steady back-and-forth between you and your baby, not perfect words.

Communication milestones at 6–9 months

Understanding (receptive)

• Turns to look when you call their name
• Responds to changes in your tone — calm versus excited
• Pays attention to music, voices and everyday sounds
• Begins to recognise familiar words like their name or "bye-bye"

Expressing (expressive)

• Babbles with repeated consonant-vowel strings — "bababa", "dadada", "mamama"
• Uses sounds and squeals to get your attention
• Laughs, coos and makes happy or unhappy sounds clearly
• Takes turns making sounds with you, as if chatting

Social communication

• Enjoys peek-a-boo and simple back-and-forth games
• Looks at your face and follows where you look
• Reaches towards things they want and may make sounds to ask

Every baby has their own pace, and some skills appear a little earlier or later. The picture across all three areas — and steady progress over time — matters more than any single milestone on its day.

When to check in

It's worth a gentle developmental check if, by around 9 months, your baby is not babbling at all, does not respond to their own name or familiar sounds, makes very little eye contact, or seems to have stopped doing something they used to do. A hearing check is always a sensible first step when communication seems slow — this is reassurance, not alarm.
