When Do Babies Respond to Their Name

The ages, and the difference between them

The CDC's revised checklist lists "looks when you call his name" at nine months. Those ages come from the 2022 revision, produced by an American Academy of Pediatrics expert group and published in Pediatrics, which reset every item to the age by which "most (≥75%) children would be expected to demonstrate the milestone". So nine months is a 75th-percentile marker, not an average and not a deadline.

The HSE describes the first appearance earlier. At seven months a baby may "begin to recognise their name and respond with a look or noise". Its hearing page puts "respond to their own name" at around nine months, alongside babbling with a variety of sounds and making eye contact readily. At twelve months, the HSE says a baby will "recognise and respond to their name more when you call them" — note the "more", which is doing honest work. Responding to a name is not all-or-nothing; it becomes more reliable over months.

ASHA agrees on the window, listing "looks at you when you call their name" in the seven to nine month band.

Why a non-response is not one thing

Three quite different explanations sit behind the same observation, and they need separating before anything else.

Attention. A nine-month-old absorbed in a toy may genuinely not register a name from across the room. The HSE captures this well: at around nine months a baby can "be easily distracted by sounds if they are paying attention to something else" — which cuts both ways. A fair test is close by, in a quiet room, with nothing more interesting in their hands.

Hearing. This is the one to rule out first, because it is common and treatable. Newborn hearing screening detects hearing loss present at birth; it does not cover hearing that changes afterwards, and glue ear after a run of colds is common in the first year. The AAP warns how easily partial hearing loss is missed: a baby may still startle at loud noises and turn towards them while struggling with quieter, more detailed sounds.

Social communication. The NHS lists "not respond to their name" among the signs of autism in young children, together with using "eye contact less often", using "fewer facial expressions and gestures", and starting "to speak at a later age than other children". One item on that list, on its own, is not a conclusion — the NHS is clear that "every autistic person is different and many autistic people will not show all the signs".

How to test it properly at home

Over a week, not once. Try it when your baby is calm and not deeply absorbed. Stand out of sight, a couple of metres away, and say their name in a normal voice — not loudly, and without banging or moving, since a baby who turns to a footstep has responded to the footstep. Try from both sides. Note whether they turn, look, still themselves, or make a sound back. Any of those counts.

Compare it with the rest of the picture. Do they turn to other sounds? Do they look up when you laugh? Do they respond to their name from one person but not another? Those details are what a clinician needs, and they are almost impossible to reconstruct from memory in an appointment.

What helps

Using the name in the right places. The NHS advice for older babies and toddlers includes getting a child's attention "by saying their name at the start of a sentence" and then giving them time to respond. The HSE's communication advice for nought to twelve months is to get face to face at about arm's length, make eye contact, "leave little pauses for them to take their turn", and turn off background noise, which it says "can be confusing and overwhelming".

Names get diluted by overuse. A baby whose name is said fifty times an hour, mostly as background, has less reason to treat it as a signal than one whose name reliably means something is about to happen.

If your baby was born early

Correct for prematurity. A baby born two months early is at seven months corrected when they turn nine months, and seven months is where the HSE places the first flicker of name recognition. The AAP advises using adjusted age for tracking development until two years, by which time most children born preterm have caught up.

When to raise it

A nine-month-old who does not respond to their name is worth an appointment, and the first question to ask for is a hearing check. The HSE lists "signs of a hearing difficulty" among the reasons to contact a GP or public health nurse, and says they may carry out more tests or refer on. In the UK, a health visitor or GP can refer to audiology.

Raise it sooner if the name is not the only thing. A baby who does not respond to their name and also does not babble, does not look at faces, does not follow a point and does not use gestures is showing a pattern rather than an item. And at any age, if your baby used to respond to their name and has stopped, ring rather than wait: the HSE repeats at every month of the first year that losing a previously held skill is a reason to make contact.
