YOUR QUESTION. A CLEARER NEXT STEP.
When Do Babies Move From Cooing to Babbling?
Babies typically coo (soft vowel sounds) from around 2–4 months and progress to babbling (repeated consonant-vowel sounds like "bababa") at around 6–9 months, with varied, conversational babble by about 12 months. It's a gradual blossoming, and small variations are normal.
In this answer 5 sections
One day it's soft, musical vowel sounds — and then, almost overnight, it becomes "bababa" with real rhythm. That shift is one of the loveliest milestones in your baby's first year.
In short
Most babies coo (soft vowel sounds like "ooh" and "aah") from around 2–4 months, then move into babbling — repeated consonant-vowel sounds like "bababa" or "dadada" — at around 6–9 months. It's a gradual blossoming rather than a sudden switch, and a little earlier or later is perfectly normal. By around 12 months you'll usually hear varied, speech-like babble that almost sounds like a conversation.
How the journey unfolds
Think of it as a sequence, each stage building on the last:
- Cooing (around 2–4 months): open vowel sounds, often when content or chatting with you. Your baby is discovering their voice.
- Vocal play (around 4–6 months): squeals, growls, raspberries, blowing bubbles — experimenting with pitch and volume.
- Canonical babbling (around 6–9 months): repeated syllables like "bababa", "mamama", "dadada". This is the big leap — true consonant-and-vowel combinations.
- Varied babbling (around 9–12 months): longer strings with different sounds and a sing-song, conversational rhythm, sometimes called jargon.
What fuels this beautifully is back-and-forth: when you respond to your baby's sounds, pause, and let them "reply", you're laying the foundations of conversation long before the first word.
A gentle note on hearing
Babbling is also a wonderful sign that your baby is hearing the sounds around them — including their own voice. If babble seems to fade rather than grow, or you don't hear any babble by around 9 months, it's worth a friendly chat with your paediatrician, who may suggest a hearing check. This is reassurance-seeking, not alarm — most babies are right on track.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
Watch for babble growing richer over months, not fading. If you hear no babble by around 9 months, or babble that disappears, mention it to your paediatrician, who may suggest a simple hearing check.
In everyday life
Copy your baby's sounds back to them, then pause and wait. This sound 'tennis' teaches conversational turn-taking and encourages more babbling.
Bring your observations and questions to your child’s professional. Choose activities that suit your child’s comfort, abilities and agreed plan.
Bring your questions to a first visitQuestions families ask
At what age should my baby start babbling?
Most babies begin true babbling — repeated consonant-vowel sounds like "bababa" — around 6 to 9 months. Before that, from about 2–4 months, you'll hear cooing (soft vowel sounds). A little earlier or later is completely normal.
What is the difference between cooing and babbling?
Cooing is open vowel sounds like "ooh" and "aah", usually from 2–4 months. Babbling adds consonants to make repeated syllables like "mamama" or "dadada", usually from around 6–9 months.
Should I worry if my baby isn't babbling by 9 months?
It's worth a friendly chat with your paediatrician, who may suggest a hearing check, especially if babble has faded rather than grown. Most babies are simply on their own timeline, so this is reassurance-seeking rather than cause for alarm.
How can I encourage my baby to babble more?
Talk and sing to your baby often, copy their sounds back, pause to let them 'reply', and name everyday things. Responsive, face-to-face back-and-forth is the best encouragement.
