Your toddler’s cousin is the same age, and she just said “I want more juice, please” with a straight face. Your toddler is currently pointing at the juice and shouting “UH!” Everyone in the room says, “Oh, they all talk on their own schedule.” And maybe they’re right. But a small voice in the back of your head wants to know: how would I even know if it were more than a schedule?
Here’s the short version: the earliest signs of a speech delay usually aren’t about how many words your child says. They show up in gestures, in understanding, and in whether your child is trying to connect with you at all. Eight signs cover most of what pediatricians and speech-language pathologists watch for, and each one comes with an age so you’re not guessing.
If you read this and nothing fits, you’ve lost five minutes. If something does, you’ll know exactly what to do next, and that you’re not overreacting by doing it.
The Myth: “Just Wait, They’ll Talk When They’re Ready”
This is the most common advice parents get, and it’s half right, which is what makes it so sticky.
The reassuring half is real. Late language emergence, which is the clinical term for a child who is slow to start talking with no other developmental delays, is common. The American Speech-Language-Hearing Association (ASHA) puts the rate at roughly 10 to 20 percent of children at age 2, and says about 50 to 70 percent of those children catch up to their peers by late preschool or school age.
The half that gets left out: the same ASHA summary notes that by age 7, about 20 percent of children with a late-talking history had a language impairment, compared with 11 percent of kids who weren’t late talkers. And even among those who reach the typical range, scores often stay a bit lower than their peers’. Nobody can tell from the outside which late talker your child will be.
That’s why the CDC’s advice isn’t “wait and see.” It’s the opposite. If your child isn’t meeting one or more milestones, has lost skills, or you simply have a concern, talk to the doctor and ask about developmental screening. Many late talkers do catch up, so waiting isn’t automatically a mistake. But you can’t tell in advance which children won’t, and screening is quick, so the cost of checking is a phone call.
Why It Feels So Hard to Tell
A few things make this stretch of parenting confusing:
“Speech” and “language” aren’t the same thing. Speech is the sounds themselves. Language is understanding and using words and gestures to share meaning. A child can understand everything and say little, or say plenty that no one can follow. The signs below cover both.
Milestones got revised. In 2022, the CDC and the American Academy of Pediatrics updated their checklists so each milestone reflects what 75 percent or more of children can do by that age, instead of the average. The lists are shorter, clearer, and include checklists at 15 and 30 months that didn’t exist before. If you’re comparing your child to an older chart, you may be looking at outdated numbers.
Every child’s pace really does vary. Plenty of toddlers focus on walking or climbing before words. That’s a pattern parents notice, not a rule, and it doesn’t explain away missing gestures or understanding.
The 8 Early Signs of Speech Delay
1. No gestures by 12 to 15 months
Gestures come before words, and they’re some of the easiest things to watch for. At 12 months, the CDC checklist expects your child to wave “bye-bye.” By 15 months, it expects them to point to ask for something or to get help.
What to watch for: A toddler who doesn’t wave, point, reach, nod, shake their head, or show you things, and relies on crying or grabbing your hand instead. By 24 months the checklist expects more gestures than just waving and pointing, like blowing a kiss or nodding yes.
2. Doesn’t respond to their name or to sounds
If a child can’t hear well, speech and language develop more slowly. The NIDCD notes that some delays are caused by hearing loss rather than a speech or language disorder, which is why a hearing test is often part of a speech or language evaluation.
What to watch for: Not turning when you say their name, not reacting to loud sounds, or hearing that seems to come and go (a cold, fluid in the ears, repeated ear infections). Mention any of those to your pediatrician, and ask for a hearing check rather than assuming it’s been covered.
3. Doesn’t seem to understand simple words or directions
Understanding comes before talking, and it’s the sign clinicians weigh heavily. A toddler with plenty of understanding and few words is on a very different path than one who doesn’t seem to follow you.
The CDC checklist gives the timeline: at 15 months, your child follows directions given with both a gesture and words (“give me the cup” while holding out your hand), and looks at a familiar object when you name it. At 18 months, they follow a one-step direction without a gesture. At 24 months, they point to things in a book when you ask, and point to at least two body parts.
What to watch for: A child who needs you to point, gesture, and demonstrate before they respond, past 18 months, or who rarely looks toward things you name.
4. Little babbling, or a very limited range of sounds
Babbling is early practice for speech. The NIDCD describes babies at 4 to 6 months babbling with a range of sounds, including p, b, and m, and imitating speech sounds by around 7 months to a year. ASHA notes that differences in babbling before age 2 may predict later vocabulary and speech delays.
What to watch for: A baby or young toddler who is mostly quiet, uses very few different sounds, or doesn’t seem to copy the sounds you make. Babbling isn’t on the CDC’s 12-month list, so treat it as supporting evidence, not a stand-alone alarm.
5. No words, or no attempts at words, for their age
This is the one everyone looks for, and the milestones are gentler than parents expect.
- 12 months: calls a parent “mama” or “dada” or another special name
- 15 months: tries to say one or two words besides “mama” or “dada,” like “ba” for ball
- 18 months: tries to say three or more words besides “mama” or “dada”
- 24 months: says at least two words together, like “more milk”
Notice that the words don’t have to be clear. “Ba” for ball counts, as long as it’s on purpose and consistent.
What to watch for: A child who’s missing the milestone for their age and isn’t making up for it with gestures. Missing one is worth a mention to your pediatrician. Missing several, or missing one while also missing gestures or understanding, is worth acting on.
6. Not combining words by 24 months
Two-word phrases are a major language milestone, and the CDC checklist at 24 months asks whether your child says at least two words together, like “more milk.” ASHA mentions a commonly used criterion for late language emergence: fewer than 50 words in expressive vocabulary and no two-word combinations by 24 months.
What to watch for: At 2, a child who uses single words only, or who has fewer than about 50 words in total. ASHA also says these criteria should be reviewed about every six months, and that comprehension, gestures, and play matter alongside the word count.
7. Losing words or skills they used to have
This is the sign that should never go on a wait-and-see list. The CDC lists lost skills as a reason to talk to your child’s doctor, full stop. A child who used to say words, babble, wave, or point and has stopped is not “just taking a break.”
What to watch for: Any loss of words, sounds, gestures, or social skills. Call your pediatrician and use the word “regression.” There are several possible causes, including hearing problems and developmental conditions, and the only way to sort them out is an evaluation. Don’t wait to see if it passes.
8. Little interest in connecting with you
Early communication is social: showing, sharing, looking, taking turns. The CDC checklists include “plays games with you, like pat-a-cake” at 12 months, “shows you an object she likes” at 15 months, and “points to show you something interesting” at 18 months.
What to watch for: A child who rarely looks at you, doesn’t bring you things to show you, doesn’t point to share interest, or doesn’t play simple back-and-forth games.
This sign overlaps with autism, so it’s worth being clear about what it does and doesn’t mean. A speech delay on its own doesn’t mean autism, and lots of children with late speech connect socially just fine. But when slow speech comes with limited eye contact, few gestures, and little sharing, that combination is exactly what screening is designed to catch. The American Academy of Pediatrics recommends autism screening at 18 and 24 months, and any time you have a concern.
Your Age-by-Age Cheat Sheet
This table pulls together the CDC language milestones with when to act. If your child was born more than 3 weeks early, use their corrected age.
| Age | CDC language and communication milestones | Talk to your doctor if |
|---|---|---|
| 12 months | Waves “bye-bye”; calls a parent “mama,” “dada,” or a special name; understands “no” | No waving, no pointing, no response to name, or no consonant babbling |
| 15 months | Tries one or two words besides “mama” and “dada”; looks at a named object; follows directions given with gesture and words; points to ask for something | No gestures, doesn’t follow gesture-plus-word directions, doesn’t look at named objects |
| 18 months | Tries three or more words besides “mama” and “dada”; follows one-step directions without gestures | Relies only on gestures or sounds, doesn’t follow simple directions even with help |
| 24 months | Says at least two words together; points to things in a book; points to at least two body parts; uses more gestures than waving and pointing | Single words only, fewer than about 50 words, or doesn’t follow simple requests |
| Any age | Keeps the skills they’ve gained | Loses a word, sound, gesture, or social skill |
Risk Factors Worth Knowing
ASHA lists several factors that raise the odds of late language, and they’re not your fault: being male (males are about three times as likely to show late language emergence), a parent or family history of late talking (23 percent versus 12 percent with no family history), being born before 37 weeks, delayed motor development, and not being an only child. Repeated middle ear infections are also part of what clinicians look at.
None of these means your child will have a delay. They mean it’s reasonable to stay a little more alert, and to ask for screening a little sooner.
What to Do If Some of These Sound Familiar
1. Write it down for a week. Note every sound, word attempt, and gesture, and what it meant. This is the most useful thing you can bring to an appointment.
2. Call your pediatrician and ask for a developmental screening. The CDC says screening is recommended for all children. Universal developmental screening is recommended at 9, 18, and 30 months, and you can ask any time you have a concern. Try: “Can we do a developmental screening today, and can we get a hearing test?”
3. Ask for a hearing evaluation. An evaluation for late speech typically includes a hearing screen to rule out hearing loss as a contributing factor.
4. Call early intervention yourself. Every state has a program for children under 3, and you can contact it directly. The CDC says a doctor’s referral isn’t necessary. Federal rules require the evaluation to be completed within 45 days of a referral, with your consent, and eligible children can get services for free or at reduced cost. Ask your state what an evaluation costs, since policies vary. You can find your state’s contact at cdc.gov/FindEI.
5. Keep talking in the meantime. Narrate your day. Pause and wait after asking a question, so your toddler has room to respond. Offer two choices instead of open questions. Read the same few books on repeat and point at the pictures. Respond to gestures as if they’re words: “Yes! The dog! You want the dog.”
6. Ask for a specialist if the doctor says to wait and you disagree. The CDC’s guidance is to ask to be connected with a specialist if concerns continue after screening. You can also ask for a referral to a speech-language pathologist directly.
What to Do Next
Pick the one sign above that nagged at you while you read. Check it against the cheat sheet. If it fits, make the call to your pediatrician this week and ask about screening and a hearing check. If it doesn’t, and your child understands you, gestures, and is slowly adding sounds and words, keep doing what you’re doing and recheck at the next well-child visit.
Either way, asking costs you a phone call. Waiting costs you time you can’t get back.
Frequently Asked Questions
What are the first signs of a speech delay?
The earliest signs tend to be missing gestures (not waving by 12 months or pointing by 15), not responding to their name or sounds, not seeming to understand simple directions, and limited babbling. Late first words come later in the picture.
At what age should I worry if my toddler isn’t talking?
There’s no single age, but the CDC checklists give clear checkpoints: a word or two besides “mama” and “dada” by 15 months, three or more by 18 months, and two words together by 24 months. The CDC’s advice is to ask about screening whenever your child isn’t meeting a milestone, has lost skills, or you have a concern.
Is a speech delay the same as a language delay?
Not exactly. Speech refers to producing sounds. Language covers understanding and using words and gestures. A child can have trouble with one or both, which is why clinicians look at understanding, communication, and sounds together.
Will my child catch up on their own?
Many do. ASHA reports that about 50 to 70 percent of children with late language emergence catch up by late preschool or school age. But you can’t tell in advance which children will, and some of the rest have lasting language difficulties, so screening is more reliable than waiting.
Does a speech delay mean my child has autism?
No. A speech delay by itself is common and often has nothing to do with autism. What matters is the full picture, including eye contact, gestures, response to name, and interest in sharing things with you. Screening looks at all of it.
Is it my fault, or caused by screens?
Late language emergence has several known risk factors, including family history and being born early, and none of them are parenting mistakes. The American Academy of Pediatrics advises against screens for children under 18 months other than video chat, and swapping screen time for talking and play is a free thing to try, but it isn’t a verdict on you.
Do I need a doctor’s referral for early intervention?
No. The CDC says parents can contact their state’s early intervention program directly.
