Parents everywhere have the same worry. You are doing the right thing by looking into it.
What Parents Should Know
According to AAP, CDC, ASHA guidelines, cooing typically begins between 6 and 8 weeks of age, with babies making soft vowel-like sounds such as "ooh" and "aah." If your baby is not cooing by 2 months, it may simply be at the later end of the normal range, but it is worth monitoring and mentioning at your next well-child visit. At 0-6 weeks, newborns primarily communicate through crying. Reflexive sounds like grunts and sighs are normal. Cooing has not yet developed at this stage, and the absence of vowel sounds is completely expected. It is generally considered normal when your baby is under 8 weeks old and communicating primarily through crying and reflexive sounds. However, you should contact your pediatrician promptly if your baby does not startle or react to loud sounds, suggesting a possible hearing concern.
Normal vs. Concerning
By Age
What to expect by age
0-6 weeks
Newborns primarily communicate through crying. Reflexive sounds like grunts and sighs are normal. Cooing has not yet developed at this stage, and the absence of vowel sounds is completely expected.
6-8 weeks
Cooing typically emerges around this time. You may hear soft "ooh," "aah," or "goo" sounds, especially during calm, alert moments. Some babies start a bit later, particularly if they were born premature. Talking and singing to your baby encourages early vocalizations.
2-3 months
Most babies are cooing regularly by now, often in response to a caregiver's voice or face. If your baby is 2 months old and not yet cooing, consider whether they respond to sounds and voices. A baby who is alert, makes eye contact, and seems to listen is likely developing normally even if cooing is slightly delayed.
3-4 months
By 3 to 4 months, babies typically coo frequently and begin experimenting with pitch and volume. If cooing has still not emerged by this age, it is important to discuss with your pediatrician, who may recommend a hearing evaluation.
4-6 months
Babies transition from cooing to vocal play, adding squeals, growls, and raspberries. If your baby has never cooed or made vowel sounds by this age, a hearing assessment and developmental evaluation are recommended to rule out any underlying concerns.
What to Tell Your Pediatrician
- Describe when you first noticed baby not cooing at 2 months and how it has changed over time.
- Note your baby's current age and which age-specific patterns you are seeing.
- Mention if your baby is past 2 months with no vowel-like sounds or cooing at all.
- Mention if your baby does not seem to react to your voice or other sounds in the environment.
- Let your doctor know if you have noticed any related concerns, such as changes in feeding, sleep, or movement patterns.
- Bring a list of any questions or observations you want to discuss at the appointment.

Baby Not Cooing
Cooing - those soft "ooh" and "aah" vowel sounds - typically begins between 6 and 8 weeks of age and becomes more frequent by 2-3 months. Some babies start a bit later, especially if they were born prematurely. If your baby is socially engaged, making eye contact, and smiling, cooing is likely just around the corner.
Baby Is Very Quiet and Not Vocalizing
Some babies are naturally quieter than others, just like some adults are more talkative than others. However, all babies should be making some sounds - cooing by 3-4 months and babbling by 7-9 months. If your baby is very quiet and rarely makes any vocal sounds, it's important to have their hearing checked and discuss their development with your pediatrician. A quiet baby isn't always a concern, but it's worth investigating.
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.

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.
