When Should a Baby Start Talking and What Is Normal?
Key takeaways
- Most babies say their first real words around 12 months and start combining two words around 24 months.
- CDC milestones now list what 75% of children can do by each age, so missing one is a prompt to ask, not panic.
- Understanding, gestures, and babbling matter as much as words when judging whether speech is on track.
Every parent watches for the first word. It usually arrives around the first birthday, and it is often "mama" or "dada" said to the right person. From there, words pile up fast.
By age two, most toddlers glue two words together. By two and a half, many use about 50 words.
That timeline is wide. Some babies talk early and never stop. Others stay quiet, then burst into sentences.
Both paths can be normal. This article explains when a baby should start talking and what is normal, including the milestone table, the wide range, and the signs that deserve a checkup.
This article is for general information, not medical advice. Talk to your child's pediatrician about any concern.
Before words: the sounds that come first
Talking starts months before the first word. Newborns cry, then coo. By about 6 months, babies babble strings of sounds like "bababa" and "mamama.
" That babble is practice, not words. The baby is learning to control lips, tongue, and breath.
Gestures come next. Waving bye-bye, pointing at a wanted toy, and lifting arms to be picked up are all communication. A baby who points, waves, and follows your gaze is building the same skills that words will use later.
When judging progress, count gestures and understanding alongside spoken words.
The milestone table
The Centers for Disease Control and Prevention (CDC) revised its developmental milestones in February 2022, with the American Academy of Pediatrics. The new checklists cover 15 and 30 months for the first time, and they changed what a milestone means. Each milestone now reflects what 75% or more of children can do by that age, up from about 50% before.
That change matters: under the new system, missing a milestone is a prompt to screen for a delay rather than a reason to wait and see.
| Age | Speech and language milestones (CDC) |
| --- | --- |
| 9 months | Makes different sounds like "mamama" and "babababa"; lifts arms to be picked up |
| 12 months | Waves bye-bye; calls a parent "mama" or "dada" or another special name; understands "no" |
| 15 months | Tries to say one or two words besides "mama" or "dada," like "ba" for ball; looks at a familiar object when named; points to ask for something |
| 18 months | Tries to say three or more words besides "mama" or "dada"; follows one-step directions without gestures |
| 24 months | Says at least two words together, like "more milk"; points to things in a book when asked |
| 30 months | Says about 50 words; says two or more words with one action word, like "Doggie run"; names things in a book when asked |
Research-based norms run higher than the CDC minimums at several ages. Studies suggest many children say 8 to 10 words by 15 months, at least 15 meaningful words by 18 months, and about 50 words by 24 months. The CDC numbers are floors, not averages.
A child above the floor is not ahead of schedule. A child below it is not automatically behind. The floor exists to catch children who need support early.
Why the range is so wide
Children reach the same milestones on different schedules. A baby who walks at 10 months may talk at 16 months. A baby who says 20 words at 14 months may not combine two until 26 months.
Temperament plays a part. So does birth order: later-born children sometimes talk later, since older siblings speak for them.
Bilingual homes raise a common worry. Research involving more than 2,300 children found no significant difference between bilingual and monolingual babies in the age they started babbling, said their first word, reached 10 words, hit 50 words, or began combining words. A bilingual toddler may know fewer words in each language than a monolingual peer, but the total vocabulary across both languages is comparable.
There is no reason to drop a language to speed things up.
What matters most is the direction of travel. A child who gains new sounds, words, or gestures month by month is moving forward, even from a slow start. A child who stalls or loses skills needs attention sooner.
Red flags worth raising
The CDC's 75% framing means a missed milestone is a reason to ask, not a diagnosis. Still, some patterns deserve a prompt conversation with your pediatrician:
- By 12 months: no babbling, no attempts to imitate sounds, no words at all, no gestures like waving.
- By 18 months: fewer than three words beyond "mama" and "dada," does not point to things, does not seem to understand simple requests.
- By 24 months: fewer than 50 words, no two-word combinations, speech that is almost entirely unintelligible to caregivers.
- At any age: loss of words or skills the child previously had.
Doctor Paul Lipkin, a member of the American Academy of Pediatrics Section on Developmental and Behavioral Pediatrics who assisted with the revisions, said in a CDC news release: "The earlier a child is identified with a developmental delay the better, as treatment as well as learning interventions can begin." Early support works. Waiting rarely helps.
Hearing is part of the picture. A child who does not respond to their name or to sounds may have a hearing problem rather than a speech problem. Mention hearing concerns at the same visit.
Ear infections can also muffle sound for weeks at a time and slow word learning.
What helps speech along
You do not need apps or flashcards. Everyday talk does the job. Narrate what you are doing in short sentences.
Name objects your baby points at. Read books together and pause to let your baby fill in a word or a sound. Sing songs with gestures.
Repeat your baby's sounds back as words: when she says "ba," answer "ball, yes, ball. "
Keep your own sentences a step ahead of your child's. If your baby uses single words, answer in two-word phrases. If she uses two words, answer in three.
This gives her a model she can reach for without drowning her in long sentences.
Screen time is not a speech teacher. Babies learn language from back-and-forth interaction with a real person, not from a screen talking at them. Short video calls with grandparents are different, since a grandparent responds.
Passive videos do not respond, and they do not count as conversation.
Give your baby reasons to talk. Put a favorite toy slightly out of reach so she has to ask. Offer two snacks and wait for a point or a word.
Pause before handing over the cup. A child who never needs to ask has little reason to speak.
What a checkup usually involves
If you raise a concern, the pediatrician will usually start with a hearing screen and a developmental screening questionnaire. Those take minutes. If the screen flags a delay, the next step is a referral for a speech-language evaluation.
A speech-language pathologist watches how your child communicates, tests understanding and expression, and recommends therapy if needed.
In many places, early intervention services for children under three are available at low or no cost. Ask your pediatrician about your local program. The evaluation is not a label.
It is a map of where your child stands and what would help.
Frequently asked questions
Is it normal for a baby to say "mama" at 8 months?
Babbling that sounds like "mama" or "dada" often starts around 6 months, but without specific meaning. The first real word, using "mama" for the actual parent, usually arrives around 12 months.
My 18-month-old says only five words. Should I worry?
The CDC floor at 18 months is three or more words besides "mama" and "dada. " Five words clears that floor. If the child also points, gestures, and understands simple requests, progress is likely on track.
Raise it at the next well-child visit if you are unsure.
Do boys talk later than girls?
On average, boys reach some language milestones slightly later than girls. The gap is small, and individual variation is far larger. The same milestone table applies to all children.
Can pacifier use delay speech?
Heavy, constant pacifier use can reduce talking practice, since a child cannot babble with a pacifier in place. Occasional use is not a known cause of delay. Talk to your pediatrician if your child uses one all day past age two.
What if my child spoke, then stopped?
Loss of words or skills at any age deserves a prompt checkup. Tell the pediatrician exactly which words disappeared and when. Bring notes or videos if you have them.
Outlook
Most babies follow a steady path from babble to first words to short sentences. The CDC milestones give you checkpoints, not deadlines. Watch the direction of travel, count gestures and understanding alongside words, and ask early if something stalls.
Early questions cost nothing. Early support helps the most.
