Perhaps your baby smiles when you sing, but there is no “ba-ba-ba” yet. It is easy to hear another baby chattering and wonder whether you have missed something.
If your baby has not started babbling by around nine months, contact your health visitor or GP rather than waiting for a first word. That is the advice from Berkshire Healthcare NHS Foundation Trust. It is a reason for a helpful conversation, not a diagnosis. You do not need to turn the next few days into an exam for your baby.
What counts as babbling?
Babbling is experimenting with speech-like sounds, often repeated consonant-and-vowel combinations such as “ba-ba-ba” or “da-da-da”. A squeal, laugh or coo is communication too, but is not quite the same thing. The CDC's nine-month milestones include making many different sounds, such as “mamamama” and “bababababa”. Those sounds do not have to mean “mama” or “dada” yet; using a special name for a parent appears on the CDC's 12-month list.
These lists describe what most babies do by an age, not a birthday deadline or a home screening test. A single quiet afternoon tells you very little. If you are not sure whether what you hear is babble, say exactly that when you ask for advice.
Three ordinary things worth noticing
You can make a short note over familiar moments, without repeatedly prompting or testing your baby:
- Sounds: What sounds have you heard this week? Are there repeated “ba”, “da” or “ma” sounds, other noises, or mostly coos and squeals? Note an example rather than a score.
- Back-and-forth: During a calm face-to-face moment, does your baby make a sound, pause or respond when you answer? Enjoy the exchange even if it is only a look or smile.
- Listening and change: Do they seem to notice familiar voices or everyday sounds? Have they stopped making sounds they previously made? Tell a professional if hearing worries you or a skill seems to have disappeared. A passed newborn hearing screen does not rule out every later hearing problem.
You are not expected to work out the cause. A health visitor or GP can look at communication and hearing alongside the rest of your baby's development and advise whether any assessment would help.
What to do today
Try one small, enjoyable exchange: sit where your baby can see your face, copy a sound they make, then leave a pause. Talk through changing a nappy or looking at a book. The NHS suggests talking, singing and responding to your baby's sounds; none of this is a treatment you must get perfectly right.
Then contact your health visitor if babbling has not started, or your GP if you cannot reach them. You might say: “My baby is nine months old and I have not heard repeated ba-ba or da-da sounds. I have heard cooing and squealing. Could we talk about their communication and whether their hearing needs checking?” Change the examples to match your baby. The NHS has a 9-to-12-month development review, but you can ask before that review; you do not need to wait for an appointment.
If your baby was born early, give the health visitor both the birth date and original due date. The NHS uses age from the due date for premature babies' developmental reviews until age two. Corrected age adds context; it is not a reason to dismiss a concern about hearing or a lost skill. Our corrected-age guide explains the distinction.
If you have noticed a loss of babbling or another skill, bring that up promptly rather than waiting for the routine review. If your baby is acutely unwell, seek medical help for the illness; this guide is about development, not urgent symptom assessment.
A little help keeping the question clear
In OBubba, Grow → Milestones has a language item called “Babbles (ba-ba, da-da, ma-ma)”. You can record the first time you genuinely notice it, or leave it unmarked. The screen says milestone ranges are guidance, not a test. It cannot assess speech or hearing, and an unmarked item is not a verdict. If you want a simple way to prepare for a conversation, our health-visitor notes checklist can help you carry a few real examples rather than a long list of worries.
You can download OBubba for that gentle record of firsts. The important part today is that you can ask a human for help, with no perfect notes required.
