My Baby Isn't Babbling at 9 Months
The short answer
Most babies are babbling with consonant-vowel sounds like "baba" or "dada" by 9 months. If your baby isn't babbling at all by this age, it's important to check their hearing first and then consider a speech evaluation. Babbling is a key building block for later language, and early intervention can make a big difference.
By Age
What to expect by age
Around 4-6 months, babies start experimenting with sounds - cooing, squealing, blowing raspberries, and making vowel sounds like "oooh" and "aaah." These sounds are playful and musical. This is the foundation for babbling, which comes next. If your baby is making these early sounds, they're on track, even if consonant babbling hasn't started yet.
By 7-9 months, babbling should include repetitive consonant-vowel combinations: "bababa," "dadada," "mamama." This is called canonical babbling. If your baby is 9 months and still only making vowel sounds or is very quiet, it's worth checking in with your pediatrician. The first step is always a hearing test - babies don't babble properly if they can't hear clearly.
At this age, babbling becomes more complex and varied - sometimes called "jargon" babbling because it sounds like the baby is having a conversation with inflection and rhythm, even though there are no real words yet. If your baby has no babbling at all by 12 months, an evaluation is definitely needed. Babbling is a stronger predictor of later language than first words are.
If your baby never babbled much and still isn't saying words, speech therapy should be started. Even if hearing is normal, some babies need support to develop the oral-motor skills and sound combinations that lead to speech. The earlier this support starts, the better the outcomes. Many babies who missed babbling but got early help go on to develop completely normal language.
What Should You Do?
When to take action
- Your baby is under 7 months and is cooing, squealing, and making vowel sounds, but hasn't started consonant babbling yet.
- Your baby babbles sometimes but not constantly - some babies are quieter than others, and that's okay as long as babbling is happening.
- Your baby is very focused on physical milestones like crawling and hasn't babbled much yet - sometimes motor-focused babies talk a bit later, though it should still be monitored.
- Your baby is 9 months and has no consonant babbling at all - only vowel sounds or silence.
- Your baby used to babble and has become quieter or stopped vocalizing.
- Your baby is making sounds but they're all the same - no variety in consonants or syllables.
- Your baby doesn't respond to sounds or doesn't seem to hear you well - this could indicate a hearing issue.
- Your baby is 12 months or older with no babbling at all.
- Your baby has completely stopped making sounds after previously babbling - any loss of skills needs immediate evaluation.
- Your baby doesn't respond to loud sounds or their name, and also isn't babbling - hearing should be tested urgently.

My Baby Is Losing Words or Skills
If your child was consistently using words and has truly stopped, this is something to act on promptly. Regression - the genuine loss of skills a child previously had - is different from a normal plateau or a toddler being too busy to talk, and it always warrants a conversation with your pediatrician sooner rather than later.
Baby Not Babbling
Babbling with consonant sounds like "ba," "da," and "ma" typically begins between 6 and 9 months and is an important building block for speech. Babies develop at different rates, but if your baby is not making any consonant sounds by 9 months, a hearing check is a good first step.
Baby Not Laughing at Peek-a-Boo
Most babies start showing delight during peek-a-boo between 6 and 9 months, when they develop "object permanence" - the understanding that things still exist when hidden. If your baby isn't laughing at peek-a-boo yet, consider their age and overall social engagement. Some babies prefer other games, and some show enjoyment through smiles or excited movements rather than laughter. What matters most is whether your baby is socially engaged with you overall.
Baby Not Making Vowel Sounds
Most babies begin making vowel sounds - those lovely "oooh," "aaah," and "eee" sounds - around 2 to 3 months of age. This early cooing is one of the first steps in language development. Some babies are naturally quieter than others, but if your baby isn't making any vowel sounds by 4 months, it's worth checking in with your pediatrician to make sure hearing and development are on track.
Baby Not Responding to Own Name Consistently
Most babies start recognizing and responding to their own name between 5 and 7 months, though consistent response may take until 9 months. It's common for babies to sometimes ignore their name when they're focused on something interesting - this is normal. However, if your baby rarely or never turns when you say their name by 9 months, it's worth discussing with your pediatrician to check hearing and development.
Baby Not Turning to Sounds
Babies typically begin turning toward sounds around 4 to 6 months of age. If your baby isn't consistently looking toward voices or noises by 6 months, it's worth having their hearing checked. In many cases, something as simple as fluid in the ears can temporarily affect hearing, and early identification leads to the best outcomes.
