By age 2, most toddlers have around 50 words and are starting to put two together, like "more milk." By age 3, they're building simple sentences, and a stranger should be able to understand roughly three out of four things they say. If your child is behind these marks, book a speech-language evaluation rather than waiting to see what happens. Time spent watching and hoping is time your child doesn't get back.
What words and sentences should a 2-year-old be saying?
By 24 months, most toddlers have at least 50 words and are starting to put two of them together, phrases like "daddy go" or "big dog." That's the milestone the American Speech-Language-Hearing Association points to.[1] It surprises a lot of parents, because they've been told their child "knows" plenty of words the child has never actually said out loud. ASHA is counting expressive vocabulary here: the words your child actually produces, not the ones they seem to understand.
At this age, a child should also be understood by familiar people roughly half the time. Their speech will still sound fuzzy, and that's expected. What matters more than clarity right now is whether new words keep showing up and whether two-word combinations are starting to appear, even just occasionally.
The range here is genuinely wide. Some 2-year-olds have 200 words, some have 50, and both can be perfectly normal. What isn't typical is a child under 50 words who never strings any together, or a vocabulary that was growing and then stalled. A plateau, or losing words a child once had, is always worth a call to the pediatrician.
It helps to watch a few things week to week: whether your child is adding new words a few times a month, whether two words are starting to land together even sloppily, and whether they point, meet your eyes, and turn when you say their name. Those social signals matter just as much as the word count at this age.[2]
What are the speech milestones from age 2 to 3?
This is the year language takes off faster than at any other point in early childhood. A child who starts at age 2 with maybe 50 words often finishes it close to 1,000. Here's roughly how it unfolds, according to the research-backed guidelines:
| Age | Vocabulary | Sentence length | Stranger intelligibility |
|---|---|---|---|
| 24 months | 50+ words | 2-word phrases | ~50% |
| 30 months | 200-300 words | 2-3 word phrases | ~60-65% |
| 36 months | 450-1000 words | 3-4 word sentences | ~75% |
Those intelligibility numbers come from Coplan and Gleason's widely cited work and show up in AAP developmental surveillance guidance.[3] By age 3, a stranger, someone who's never spent time around your child, should be able to understand about 75% of what they say. If you understand nearly everything but the preschool teacher is lost most of the time, that gap itself is useful information.
By 36 months, most kids are asking simple questions, using plurals reasonably well, calling themselves "I" or "me" instead of just their name, and can tell you about something that happened earlier that day. These aren't bonus skills. They're what a child needs to get along with other kids and walk into school ready.
What the chart can't show you is pace. Somewhere between 18 and 30 months, most children go through a vocabulary explosion, sometimes adding several new words a day. If that growth has slowed way down or gone backward, that pattern matters more than whatever number they're stuck at.
What counts as a late talker at age 2?
A late talker is a toddler between 18 and 30 months whose expressive vocabulary is smaller than expected, even though hearing, comprehension, play, and social skills all look typical.[4] Somewhere between 10 and 20 percent of 2-year-olds fit that description, depending on which study and cutoff you look at. The word count lags. Everything else checks out.
That label covers a lot of ground, though. Some late talkers, what older research called "late bloomers," do catch up on their own, usually by age 4 or 5. But long-term follow-up work, including research out of the University of Melbourne, finds that a real portion of late talkers, something like 20 to 40 percent across most groups studied, still have language difficulties once they reach school.[4] At age 2, there's no way to know which group a given child belongs to.
That's really the argument for getting a concern checked rather than sitting on it. An evaluation doesn't commit you to years of therapy. It just tells you where your child stands right now and whether stepping in makes sense.[3]
A few things at age 2 make it more likely a child will need support beyond the toddler years: fewer than 50 words by 24 months, no two-word combinations by 24 months, a family history of language delay, being a boy (boys are delayed at roughly twice the rate of girls), and not much pointing or pretend play. None of these on its own is a diagnosis. Seen together, they're a good reason to get things checked sooner rather than later.
What's the difference between a 2-year-old not talking and a 3-year-old not talking?
A 2-year-old who isn't saying much falls into the range where a pediatrician might reasonably suggest waiting and watching. A 3-year-old who still isn't putting words into sentences is a different situation. By 36 months, that wait-and-see window has closed.
At 3, kids are expected to do a lot with language: follow directions that involve more than one step, hold up their end of a conversation, and be understood by people outside the family. A child at this age who's still speaking only in single words has passed the late-talker threshold, and that's usually not a case of a slower timeline sorting itself out. It's worth looking into.[1]
When a 3-year-old is nonverbal or says very little, an evaluation considers a few different explanations: a language disorder (which might affect understanding, speaking, or both), childhood apraxia of speech, autism, hearing loss, or some combination. None of these can be confirmed or ruled out without a real assessment, which is why it's worth seeing a speech-language pathologist who can run a standardized evaluation and send you for hearing testing if needed.
If your 3-year-old isn't talking in sentences, ask your pediatrician for a referral, and if you haven't already, look into an early intervention evaluation through your state's Part C or Part B program. You can pursue both at once, and at this age, time matters more than it did back at 18 months.
What causes a toddler to not talk at 2 years?
There's no single answer here, and that's not a dodge, it's just how language delay works. It comes from several different sources, which is exactly why a child needs an evaluation instead of a mental checklist of possible causes.
Hearing loss is the first thing to rule out. Even mild hearing loss that comes and goes with repeated ear infections can throw off how a child learns language. About 1 to 3 per 1,000 newborns have significant hearing loss at birth, and more develop it later in early childhood.[5] A hearing test belongs before or alongside a speech evaluation, not after it.
Autism goes hand in hand with language delay for many children, though not all. The average age of autism diagnosis in the U.S. is around 4 years, but screening tools like the M-CHAT-R are designed for 18 and 24 months, well before a formal diagnosis would typically happen.[6] If language delay shows up alongside limited eye contact, repetitive behaviors, or strong sensory reactions, that combination is worth screening for autism over. When autism is identified, speech therapy built specifically for autism looks different from general language therapy and is worth reading about on its own.
Childhood apraxia of speech is a different kind of problem, a motor one, where the child knows exactly what they want to say but struggles to plan and sequence the movements needed to say it. It's uncommon (estimates run 1 to 2 per 1,000 children) but gets missed or mislabeled in toddlers fairly often.[7] If you want to understand what it actually involves, there's a fuller look at childhood apraxia of speech.
Expressive language disorder on its own, developmental delay with no identifiable cause, and family patterns account for a large share of cases too. Plenty of kids have a parent or sibling who talked late and caught up fine. That family history matters to an SLP and is worth mentioning at an evaluation, but it doesn't change the underlying advice: get it checked rather than wait and see.
Some signs mean call your pediatrician right away, whatever your child's age: no babbling by 12 months, no single words by 16 months, no two-word phrases by 24 months, any loss of language skills at any age, not responding to their name by 12 months, and not pointing to show interest by 14 months.[2]
The AAP recommends developmental surveillance at every well-child visit, standardized developmental screening at 9, 18, and 30 months, and autism-specific screening at 18 and 24 months.[3] If those screenings aren't happening at your child's appointments, ask for them by name.
For a 2-to-3-year-old, watch for a vocabulary that isn't growing, sentences stuck at two words well past 30 months, speech you can't understand most of the time, and meltdowns driven by not being able to communicate. That last one matters more than a lot of parents realize. A child who can't get a need across is under real pressure, and it tends to leak into behavior, sleep, and learning.
If your child repeats words or phrases in a way that feels like echoing rather than talking to you, it's worth looking into. That pattern is sometimes echolalia, which shows up in typical development and in some neurodivergent kids too. It isn't automatically something to worry about; what matters is the context it happens in and how consistent the pattern is.
Getting help before and after age 3
If your child is under 3, the Individuals with Disabilities Education Act (IDEA) guarantees free early intervention for developmental delays, including speech and language, under Part C of the law.[8] You don't need a doctor's referral, just call your state's early intervention program directly and ask for an evaluation.
Once your child turns 3, services shift to Part B of IDEA, run through your local school district instead. If your child qualifies, they get an Individualized Education Program (IEP) and services at no cost to you.[8]
Some children don't meet IDEA's eligibility thresholds, and some families would rather go a private route from the start. In that case, speech-language therapy through a private SLP or a hospital outpatient clinic is the usual alternative. Sessions typically run 30 to 60 minutes, once or twice a week, with home practice built in between visits. How involved parents get is one of the strongest predictors of how well early language intervention works.[9]
What actually happens in a session depends a lot on the child. A late talker with no other diagnosis will usually work on getting more chances to communicate, having every attempt responded to, and hearing language modeled just a step above where they are now. Apraxia calls for something different: motor-based practice, repeated in a structured way. An autistic child's therapy often weaves social communication goals in alongside speech. A good SLP fits the method to the child in front of them, since "speech therapy" isn't one single thing, no matter how often the term gets used that way.
One thing worth knowing before you start: early intervention programs have wait lists in many states, sometimes stretching for months. It's worth putting in the referral before you're fully certain you need it. You can always step back later if your child's language takes off on its own.
What helps at home
The research on parent-run language strategies is solid, and it points to specific techniques rather than vague "talk to your child more" advice.
Start by following your child's lead. Get on the floor, watch what grabs their attention, and comment on it: "Oh, the truck! Big red truck." You're modeling language right where the child's attention already is, and that's when it sticks best.[9]
Try parallel talk too: narrate what your child is doing without waiting for a reply. "You're pouring the water. Splash! Cold water." This isn't the same as asking questions, which can put a child on the spot. Parallel talk just pours language over what's already happening, no pressure to respond.
When your child says "ball," you can say "yes, ball. Big ball. Throw the ball." You're taking what they gave you and modeling one level up. Speech-language pathologists call this recasting, and it has a decent evidence base for lifting word output.[9]
It also helps to cut back on questions and commands. Parents of late talkers tend to pile these on: "What's that? Say ball! Can you say ball?" It's an understandable instinct, but it tends to backfire. Questions pressure communication, while comments invite it.
Reading together matters too, and you don't have to read every word on the page. Talk about the pictures, point, name things, make sounds. The vocabulary payoff from shared book reading is well documented.[10]
Screens are worth watching closely. The AAP recommends no screens beyond video chat for children under 18 months, and only high-quality, co-viewed programming for those 18 to 24 months. For toddlers with language delays, passive screen time simply doesn't build vocabulary the way back-and-forth talk does.[2]
And sing. Songs with repeated, predictable lines ("Old MacDonald," "Wheels on the Bus") give toddlers a low-pressure spot to fill in a word. Many late talkers say their first words in a song before they ever manage a sentence. That's real, so use it.
Will my child just catch up?
Maybe, honestly. Research does support that some late talkers at 24 months have typical language by age 4 or 5 with no intervention at all. The catch is that no clinician can tell you at age 2 which group your child is in, not with any confidence.
A few things point toward catching up without help: understanding close to what's typical for their age, a good range of sounds showing up in babbling and early words, strong pretend play, and easy back-and-forth with the people around them. Kids who are quiet but clearly tuned in and connected tend to do better than kids who are quiet and withdrawn.[4]
What tends to signal a delay that sticks around: fewer than 50 words and no word combinations at 24 months, weak comprehension, little pointing or shared attention, and a family history of language or reading trouble. Boys are delayed at roughly double the rate of girls, and boys with several of these risk factors together are less likely to catch up on their own.
Even when a child does catch up naturally, ASHA and the AAP both land in the same place: early evaluation, and early intervention where it fits, beats waiting around. If a child catches up after six months of therapy, that's not proof the therapy did nothing. It might mean the therapy worked.
For families who want extra support during this stretch, apps built for practicing language at home, like Little Words, can help parents track progress and run language-building activities between therapy sessions. Daily practice, done consistently, adds up.
If you're worried about your child's speech, that worry alone is reason enough to get an evaluation. You don't need your pediatrician to sign off first. Both ASHA and the AAP are clear that parent concern counts as clinically meaningful on its own.[1] [3] If your 24-month-old has fewer than 50 words or isn't putting two words together, ask for a referral to a speech-language pathologist. Don't settle for "let's see how they're doing at 3" unless there's an actual plan attached to that waiting period. And if your 3-year-old isn't talking in sentences yet, that's past the point of watching and waiting: get a full speech and language evaluation on the calendar as soon as you can, and ask about your state's early intervention or school-based options at the same time, since those run on a separate track from a private evaluation. Finding an SLP isn't complicated. Your pediatrician can refer you, or you can search ASHA's directory at findmyslp.asha.org yourself. Your state's early intervention program is just a phone call away, and once a child turns 3, the local public school district is required to evaluate at no cost.[8] If in-person appointments are scarce or booked out for months, it's worth looking into speech therapy over video with a licensed SLP. It's grown a lot since 2020 and works well for many toddlers, particularly for parent-coaching sessions where the SLP teaches you techniques to use at home between visits. Most parents put off evaluations because they picture something clinical and scary for their child. It's usually the opposite. For a toddler, the whole thing is mostly play: the SLP gets down on the floor with toys, books, and bubbles and watches how your child communicates, or doesn't. They'll use standardized tests like the Preschool Language Scales (PLS-5) or the Receptive-Expressive Emergent Language Test (REEL-4) to see how your child's skills compare to other kids the same age, and they'll ask you plenty of questions about your child's development along the way.[11] The evaluation looks at both sides of language: what a child produces (words, sounds, sentences) and what a child understands (following directions, pointing to named pictures). Those two skills can be surprisingly far apart. Some toddlers understand far more than they say. Others struggle with both, and the shape of that gap is really what shapes the plan afterward. You'll usually get results the same day, or at a follow-up within a week. The SLP will tell you whether your child's skills are typical, below typical, or significantly below typical, and lay out what they recommend. If therapy makes sense, you'll hear an early version of the goals and how often sessions would happen. Evaluations through your school district or early intervention program are free. Private evaluations run roughly $200 to $500 out of pocket depending on location and provider, though many are covered by insurance, so it's worth calling ahead and asking about coverage and in-network SLPs. A speech delay by itself doesn't mean a child is autistic, and plenty of autistic kids have strong early language skills. There's a real connection between the two, but it isn't a one-to-one match: speech and language delays are just one of the more common signs that lead a family toward an autism evaluation in the first place. The CDC estimates that about 1 in 36 children in the United States is identified with autism spectrum disorder.[6] The core features are differences in social communication along with restricted interests or repetitive behaviors. Language delay often shows up alongside these traits, but it isn't required for a diagnosis. Speech-language pathologists and developmental pediatricians look well past spoken words. They watch whether a child points or shows objects to others, whether eye contact happens and holds, whether the child turns reliably to their name, and whether play flows back and forth between two people rather than staying narrow and repetitive. One pattern worth mentioning to a specialist: a toddler whose speech is mostly repetition, echoing lines from TV shows or books without using them to actually communicate. Our piece on what echolalia looks like in young kids walks through how to tell the typical version from the kind that deserves a closer look. You don't have to wait for one evaluation to finish before starting another. An autism evaluation and a speech-language evaluation can happen side by side. And if autism is confirmed, therapy built specifically for autistic children tends to work better than general language therapy.Frequently asked questions
How many words should a 2-year-old say?
At least 50 words by 24 months, per ASHA guidelines. That's expressive vocabulary, words your child actually says, not just understands. Two-word combinations ("more juice," "daddy go") should also be showing up by then. If your child has fewer than 50 words or no word combinations at 2, arrange an evaluation with a speech-language pathologist now rather than later.
My toddler is not talking at 2 years. Should I worry?
A 2-year-old talking very little is worth taking seriously. About 10 to 20 percent of 2-year-olds are late talkers. Some catch up on their own, but a meaningful share go on to have lasting language or reading difficulties. The AAP and ASHA both recommend evaluation over waiting. A speech-language assessment will tell you where your child stands and what, if anything, to do next.
What's the difference between a late talker and a speech delay?
A late talker is a toddler (usually 18 to 30 months) with a smaller vocabulary than expected but otherwise typical development: good comprehension, social engagement, and play. Speech delay is a broader term for any gap between a child's communication skills and age expectations. A late talker is really just one type of speech delay. An evaluation will clarify which fits your child and whether there's an underlying cause.
My 3-year-old toddler is not talking in sentences. Is that a problem?
By 36 months, most children produce three-to-four-word sentences and are understood by strangers about 75% of the time. A 3-year-old still not talking in sentences has moved past the typical late-talker window and warrants a full speech-language evaluation. Ask your pediatrician for a referral and contact your local school district about a free evaluation, since Part B of IDEA covers children 3 and older.
Can a 2-year-old who doesn't talk still be developing normally?
It depends what "doesn't talk" means. A child with fewer than 50 words and no combinations at 24 months is below the expected milestone, even if everything else looks fine. That doesn't mean they won't catch up, but it does mean an evaluation makes sense. Comprehension, social engagement, and play all matter here too.
What should I do if my 2-year-old only says a few words?
Talk to your pediatrician and ask for a referral to a speech-language pathologist. You can also call your state's early intervention program directly (no referral needed) for a free evaluation under Part C of IDEA. While you wait for appointments, follow your child's lead, narrate what they're doing, and ease off the questions. What you do at home between sessions matters more than people expect.
How do I get my toddler evaluated for free?
In the U.S., Part C of IDEA provides free evaluations for children under 3 with developmental delays, speech delays included, and you contact your state's early intervention program directly. For children 3 and older, Part B of IDEA means your local public school district must evaluate at no cost. Both are separate from private evaluations through hospitals or private SLPs, which insurance often covers.
Is screen time causing my toddler's speech delay?
Heavy passive screen time is linked to slower language development in toddlers, but the relationship is correlational, not cleanly causal. The AAP recommends limiting screens for children under 2 and choosing interactive content viewed with a caregiver for children 18 to 24 months. What's clearer is that back-and-forth with real people builds language, and passive viewing doesn't replace it. Cutting screens won't fix a significant delay on its own, but it helps.
My 3-year-old is still not talking much. Could it be apraxia of speech?
Childhood apraxia of speech is a motor speech disorder where the brain struggles to plan the movements for speech. It can cause big delays in a 2-to-3-year-old and often gets missed early. Signs include very few speech sounds, inconsistent errors, and speech that doesn't improve quickly with typical modeling. An SLP evaluation can assess for apraxia specifically. Read more in our overview of childhood apraxia of speech.
Does bilingual exposure cause speech delays?
No. Research consistently shows bilingual children hit overall language milestones at the same age as monolingual peers, though vocabulary in each single language may be smaller. An SLP evaluating a bilingual child should assess both languages and count total vocabulary across them. A bilingual child with a true language delay will show that delay in both languages, not just one.
What's the best speech therapy approach for a 2-year-old late talker?
For a child who is mainly a late talker without other diagnoses, therapy usually centers on naturalistic developmental behavioral interventions: following the child's lead, expanding their utterances, and coaching parents to do the same at home. Parent involvement is one of the strongest predictors of outcome. The approach shifts if apraxia, autism, or another condition is involved, so a good SLP matches the method to the child.
At what age is it too late for speech therapy to help?
It's never too late for speech therapy to help, but earlier really is better. The brain is most plastic for language in the first five years of life. Older children still make real gains, but the return on early intervention is higher. If you're past the toddler years and still looking for support, a speech-language pathologist can assess and work with children and adults at any age.
Should I use sign language with a toddler who isn't talking?
Yes, for most children, and the research backs it up. Teaching simple signs (more, eat, help, all done) gives a non-speaking or barely-speaking toddler a way to communicate that cuts down on frustration. Signing does not delay speech in children without hearing loss, and for some toddlers it actually speeds up spoken words by bridging the gap between intention and output. An SLP can help you pick the most useful signs to start with.
What is AAC and does my toddler need it?
AAC stands for augmentative and alternative communication: any tool or strategy that adds to or replaces speech, from picture boards to speech-generating devices. AAC doesn't block spoken language; research shows it often supports it instead. If your toddler has very limited speech and few ways to get needs across, an SLP can assess whether an AAC system would help. Read more in our overview of AAC devices.
