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.
Parents everywhere have the same worry. You are doing the right thing by looking into it.
By Age
What to expect by age
4-6 months
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.
7-9 months
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.
10-12 months
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.
13-18 months
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.

Related Speech Concerns
Accent vs Speech Disorder in Bilingual Toddlers
When toddlers grow up hearing more than one language, they naturally blend sounds, patterns, and accents from both languages. This is normal and healthy, not a speech disorder. A bilingual child may pronounce some sounds differently than monolingual peers because they are learning the sound systems of two languages simultaneously. True speech disorders affect both languages equally, while accent influence appears only in specific sounds borrowed from one language to another.
Ear Fluid Affecting Baby's Speech Development
Chronic or recurrent middle ear fluid (otitis media with effusion) can temporarily reduce hearing by 15 to 40 decibels, which is like hearing through water. During critical periods of language learning, this muffled hearing can impact speech and language development. If your baby has frequent ear infections or persistent fluid, discuss the potential speech impact with your pediatrician.
Will Ear Tubes Help My Child's Speech?
Ear tubes (tympanostomy tubes) can restore normal hearing by draining persistent fluid from the middle ear. Many children show speech and language improvement within weeks to months after tube placement, particularly if hearing loss from fluid was contributing to their speech delay. However, ear tubes alone may not resolve all speech delays, and some children benefit from speech therapy alongside tube placement.
Baby Failed Newborn Hearing Screen - What Now?
Failing a newborn hearing screen does not necessarily mean your baby has hearing loss. Many babies who fail the initial screen pass on follow-up testing. However, it is critical to complete follow-up testing by 3 months of age. If hearing loss is confirmed, early intervention by 6 months of age leads to significantly better language outcomes.
Baby Using Jargon but No Real Words
Jargon babbling, which sounds like your baby is having a conversation in a made-up language, typically appears between 10 and 14 months and is a positive sign that your baby is learning the rhythm and melody of speech. Real words usually emerge from jargon over the following months. If no real words appear by 16 to 18 months, a speech evaluation may be helpful.
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.
