Coos and makes vowel sounds
What it is
Makes sounds other than crying — 'ooh', 'aah' — often in response to you.
Start preparing
- Talk to the baby during every diaper change and feed — narrate what you do.
- When the baby makes a sound, repeat it back and wait for another.
- Sing; the rhythm holds attention longer than speech.
When to check with a professional
No cooing or other sounds by 4 months, or not responding to loud sounds, is worth mentioning to the nurse (hearing check). Development varies widely; this is a prompt to ask, not a diagnosis.
