Baby Language Milestones: From Coos to First Words
Baby Language Milestones: From Coos to First Words
First they cry. Then they coo. Then they babble nonsense for months. Then suddenly: "MAMA." And you cry again. Full circle.
Language development starts from day one—long before actual words appear. Here's the complete roadmap from newborn sounds to first sentences, including when to celebrate and when to check in with your pediatrician.
Language Development Timeline
Newborn to 2 Months: Sounds Begin
- Crying: The first communication (different cries for different needs)
- Reflexive sounds: Grunts, sighs, coughs
- Cooing begins: Vowel sounds like "ooh," "aah" (around 6-8 weeks)
- Responds to voices: Calms to familiar voices, startles at loud sounds
- Turn-taking: Early back-and-forth "conversations" with pauses
3-4 Months: Vocal Play
- Laughing: Real belly laughs
- Squealing: High-pitched happy sounds
- Varied cooing: More vowel combinations
- Blowing raspberries: Messy but developmentally important
- Responding to sounds: Turns toward voices, music
5-6 Months: Babbling Begins
- Consonant sounds emerge: "ba," "da," "ma," "ga"
- Single syllables: Repeating one sound
- Responds to own name: Turns when called (sometimes)
- Expressive sounds: Different tones for different emotions
- Imitating tones: Copying your speech rhythms
7-9 Months: Canonical Babbling
- Repeated syllables: "ba-ba-ba," "da-da-da," "ma-ma-ma"
- Sound combinations: Stringing different syllables together
- Speech-like rhythm: Babbling sounds like talking (just nonsense)
- Understanding begins: Responds to "no," waves bye-bye on cue
- Pointing: Gestures toward objects
"Ma-ma" and "Da-da" Truth:
These sounds usually appear at 6-9 months but are often NOT directed at parents yet. They're practicing sounds. "Mama" used specifically FOR you typically comes around 10-14 months. Don't be heartbroken—it's coming.
10-12 Months: First Words!
- First true words: Used consistently for specific things/people
- Typical first words: Mama, Dada, ball, dog, more, no
- Jargon babbling: Long strings of sounds with sentence intonation
- Understanding expands: Follows simple commands ("Give me the ball")
- Pointing with purpose: Points to things they want or want to share
- Word count: 1-3 words by 12 months (some have none—still normal)
Language Milestones: Summary Table
| Age | Expression (What They Say) | Understanding (What They Get) |
|---|---|---|
| 0-2 months | Crying, cooing, vowel sounds | Recognizes voices, responds to tone |
| 3-4 months | Laughing, squealing, varied sounds | Turns toward sounds |
| 5-6 months | Consonants emerge, single syllables | Responds to name |
| 7-9 months | Canonical babbling (ba-ba, da-da) | "No," simple words, gestures |
| 10-12 months | 1-3 words, jargon with intonation | Simple commands, points |
How to Support Language Development
Talk. A Lot. About Everything.
Narrate your day. Describe what you're doing, what baby's doing, what you see. It feels awkward at first. Do it anyway.
- "Now we're changing your diaper. There's a snap. And another snap."
- "Look at the dog! The dog is big and brown. The dog says woof."
- "Time to eat. Here comes the spoon. Open wide!"
Read Daily
Even to newborns. They won't understand, but they're absorbing rhythm, tone, vocabulary, and the joy of stories. Board books with simple pictures are perfect.
Respond and Expand
When baby coos, coo back. When they babble "ba-ba," say "Yes! Ball! You want the ball?" This teaches conversation rhythm and models words.
Sing Songs
Nursery rhymes, made-up songs, whatever. Music activates language centers and babies love repetition.
Limit Screen Time
Screens don't teach language the way interaction does. The AAP recommends no screen time under 18 months (except video chatting with family).
When to Talk to Your Pediatrician
Language development varies widely, but red flags include:
By 6 Months:
- Doesn't coo or make vowel sounds
- Doesn't respond to sounds or voices
- Doesn't look at you when you talk
By 9 Months:
- No babbling at all
- Doesn't respond to their name
- Doesn't understand simple words like "no"
By 12 Months:
- No babbling with consonants (ba, da, ma)
- Doesn't point or wave
- Doesn't respond to simple commands
- Lost skills they previously had
Early Intervention Matters:
If you have concerns, don't wait. Early intervention services are available from birth and are most effective when started early. Trust your instincts—you know your baby best.
Common Questions
"My baby isn't saying any words at 12 months"
Normal range extends to 16-18 months for first words. Focus on understanding (receptive language) and communication attempts (pointing, gestures). These predict language more than early words do.
"Should we use baby sign language?"
Baby sign can reduce frustration and boost communication before verbal language develops. It does NOT delay speech—research shows it may even support it.
"We speak two languages at home"
Bilingualism is a gift. Babies can learn multiple languages simultaneously. They may mix languages at first—this is normal and resolves. Keep speaking both.
The Bottom Line
Remember This:
Language development starts at birth. Every sound you make, every word you speak, every book you read is building your baby's brain. Talk to your baby constantly—even when they can't talk back yet.
Understanding comes before speaking. The words are coming. Keep talking, keep reading, keep responding to every coo and babble.
