Speech Delay in My Child
The short answer
Speech delay means a child is developing speech and language skills in the expected order but at a slower pace than typical. It's one of the most common developmental concerns - affecting about 10-15% of toddlers - and early intervention through speech therapy is remarkably effective, with many children catching up fully by school age.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
0-12 months
During the first year, pre-speech milestones matter most: cooing by 2-3 months, babbling with consonants by 6-9 months, and responding to their name. Babies who are quiet but socially engaged - smiling, making eye contact, and responding to voices - are usually developing normally. A very quiet baby who also doesn't engage socially may benefit from early evaluation.
12-18 months
By 12 months, most babies have at least one word and understand simple phrases. By 18 months, the expectation is about 5-20 words. If your child has no words by 18 months but is pointing, gesturing, and understanding language, they may be a "late talker" - a category with generally excellent outcomes, especially with support.
18-24 months
This is when many speech delays become apparent. The CDC recommends evaluation if a child has fewer than 50 words by 24 months or isn't combining words. Importantly, hearing should always be tested as a first step - undiagnosed hearing loss is a common and very treatable cause of speech delay.
2-3 years
By age 2, children typically use 2-word phrases, and by age 3, they're speaking in short sentences that strangers can understand about 75% of the time. If your child is significantly behind these benchmarks, speech-language therapy can help. Research consistently shows that earlier intervention leads to better outcomes.
What Should You Do?
When to take action
- Your child is meeting pre-speech milestones (babbling, gesturing, pointing) even though words are slow to arrive.
- Your child understands far more than they can say - they follow directions, identify objects, and respond to questions with actions even if not with words.
- There's a family history of late talking with eventual catch-up, and your child is otherwise developing typically.
- Your child is in a bilingual or multilingual environment - these children may have fewer words in each individual language but a combined vocabulary that's on track.
- Your child is adding new words steadily, even if the total count is below average.
- No words by 18 months, even if your child is communicating with gestures.
- Fewer than 50 words by 24 months, or no two-word combinations.
- Your child's speech progress seems to have stalled - no new words for several weeks.
- Strangers can't understand any of your 2-year-old's speech.
- Your child has lost words or language skills they previously had - regression is always a reason for prompt evaluation.
- Your child has no words AND limited comprehension, no gestures, no pointing, and limited social engagement - this pattern warrants comprehensive evaluation.
- You suspect your child may not be hearing well - they don't startle at loud sounds, don't turn toward voices, or need the TV unusually loud.

Related Speech Concerns
My Baby Isn't Talking
First words typically appear between 10 and 14 months, but there's enormous variation in what's normal. What matters most at first is whether your baby is communicating - pointing, gesturing, making eye contact, and babbling with different sounds - even if actual words haven't arrived yet.
My Child Is a Late Talker
Late talkers are children who have fewer than 50 words or aren't combining words by age 2, but are developing normally in other areas. About half of late talkers catch up on their own by age 3, but the other half go on to have lasting language delays. Early evaluation and speech therapy can make a big difference, so it's worth acting even if you're told to "wait and see."
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 Using Gestures
Gestures - like pointing, waving, reaching, clapping, and shaking their head - are among the most important early communication milestones. Most babies start using gestures between 9 and 12 months. Gestures actually predict later language development better than early words do, so if your baby is gesturing, their language is likely developing well even if words are slow to come.
My Baby Isn't Pointing
Pointing typically develops between 12 and 14 months and is considered one of the most important social communication milestones. It shows your baby wants to share their world with you. If your baby isn't pointing by 18 months, a developmental evaluation is recommended - but there are lots of other ways babies start communicating that are worth noticing too.
Is Bilingualism Causing My Baby's Speech Delay?
Bilingualism does not cause speech delays. Bilingual children may take slightly longer to say their first words in each individual language, but when you count words in both languages together, they're right on track. If your bilingual child has fewer than 10 total words (in any language) by 18 months or fewer than 50 by age 2, that's a delay - and you should get a speech evaluation, not drop a language.
