At what age should a toddler be talking?

Last updated 2026-07-09

What speech milestones look like at each age

The most widely used reference points come from the American Speech-Language-Hearing Association (ASHA) and the American Academy of Pediatrics (AAP), both of which publish developmental norms drawn from large population studies. Here's what the research says about typical speech and language development from birth through age 3.^[1][2]

A few things worth knowing about these numbers: they describe the median, not a hard cutoff. Roughly half of typical children reach each milestone slightly before the listed age and half slightly after. The thresholds above sit in the 75th-to-90th percentile range that most clinical guidelines treat as the point where a clinician should pay closer attention. A child who uses only 8 words at 18 months isn't automatically diagnosed with anything, but that child is below the expected range, and a screening is warranted.^[2]

How much a child understands matters at least as much as how many words come out. A 14-month-old who doesn't respond to her name, or doesn't look toward familiar objects when you name them, is showing something worth paying attention to, no matter how much she babbles.

What counts as a real word

A real word is any consistent sound or approximation a child uses on purpose to mean the same thing every time. "Ba" for bottle counts if your child always uses it to mean bottle. "Dada" counts the moment your child uses it specifically for their father rather than random babble. Pronunciation is irrelevant at this stage.^[1]

This trips up a lot of parents. What doesn't count: random babble sounds, immediate echoing of what you just said with no apparent intent, or a word used once and never again. Consistent, intentional, and tied to a specific meaning, that's the test.

The distinction matters because parents often over-count or under-count, and it changes the clinical picture. A parent who counts "mama" every time their child babbles it may believe their child has 10 words when they have 3. A parent who only counts perfect pronunciation may believe their child has 2 words when they have 15. When you talk to a pediatrician or speech-language pathologist, bring a written list of the words your child uses, what each one means, and how consistently they use it. That list beats a rough number every time.

Red flags worth acting on

The AAP recommends that pediatricians screen every child for developmental delays at the 9-month, 18-month, and 24- or 30-month well-child visits, with autism-specific screening at 18 and 24 months.^[2] You don't have to wait for a scheduled visit if you notice any of the following.

Call promptly if your child, at any age, loses words or communication skills they previously had (regression is always a reason to call that week, not at the next scheduled visit), doesn't babble by 12 months, doesn't use any gestures like pointing, waving, or reaching to be picked up by 12 months, doesn't use at least one real word by 16 months, doesn't combine two words by 24 months (not counting echolalia), or doesn't respond to their name consistently by 12 months.

Echolalia, repeating words or phrases with no apparent meaning, deserves its own note. Some echolalia is normal and expected in children under 2.5 as they build language. But persistent echolalia, where a child's speech is almost entirely repetition, especially of TV phrases or things said to them, can signal that functional communication isn't developing as expected.^[3]

No single sign diagnoses anything. A child with chronic ear infections may have a temporary hearing-related delay that clears completely once the infections resolve. A child in a bilingual home may spread words across two languages but hold a typical total vocabulary. Context matters, and a speech-language pathologist (SLP) is the right person to sort it out.

Speech delay versus language delay

These aren't the same thing, and the distinction guides what kind of help your child needs.

Speech delay means trouble with the physical production of sounds, words, or sentences: the child knows what they want to say but has trouble getting the sounds out correctly or fluently. A child with apraxia of speech, or a child whose articulation is hard for strangers to understand at age 3, has a speech issue.

Language delay means trouble with the system of language itself, either understanding it (receptive delay) or using it to convey meaning (expressive delay). A child who produces sounds clearly but doesn't combine words into phrases at 24 months has an expressive language delay. A child who doesn't follow two-step directions at 24 months may have a receptive language delay.

Many children have both, some have primarily one or the other, and an SLP evaluates both during a full assessment, which is why a complete evaluation tells you more than a quick screen.^[1]

Childhood apraxia of speech is one specific diagnosis worth knowing about if your child seems to understand a lot but struggles hard with producing words consistently. It's a motor speech disorder, not a language disorder, and it responds to a specific type of therapy that looks different from general language work.

How common these delays actually are

Speech and language delay is the most common developmental concern of the toddler years. About 15 to 20 percent of 2-year-olds are considered late talkers, meaning they have fewer than 50 words and no two-word combinations at 24 months but show no other developmental concerns.^[4] Of those late talkers, research suggests roughly 50 percent catch up without formal intervention by age 3 to 5 (sometimes called "late bloomers"), while the other half keep showing language differences that benefit from therapy.^[4]

Here's the hard part: nobody has a reliable way to predict at age 2 which group your child will land in. Waiting to find out means possibly losing the window when early intervention works best, which is the core argument for acting early rather than watching and waiting.

Beyond late talkers, speech and language disorders affect an estimated 8 to 9 percent of young children in the United States.^[5] Among children diagnosed with autism spectrum disorder, communication differences are part of the diagnostic criteria, and roughly 25 to 30 percent of autistic individuals are minimally verbal or non-speaking.^[6] For those children, AAC devices and autism spectrum speech therapy open communication pathways that spoken words alone may not.

Late talker or speech disorder?

A late talker is informally defined as a child aged 18 to 30 months whose expressive vocabulary is below expected levels but who develops typically in every other area: good social engagement, good comprehension, typical motor development, no hearing loss. "Late talker" is a descriptive label, not a diagnosis.^[4]

A speech or language disorder is a diagnosed condition, identified through standardized testing by an SLP. Diagnoses that can affect toddler speech include expressive language disorder, receptive-expressive language disorder, childhood apraxia of speech, phonological disorder, and, separately, autism spectrum disorder, in which communication differences are part of a broader profile.

A late talker may or may not go on to get a formal diagnosis; many don't. But because there's no way to know at 20 months which child will catch up and which won't, the guidance from ASHA and the AAP is plain: refer for a speech-language evaluation, don't wait.^[1][2]

Early intervention services in the United States are available under IDEA Part C for children under age 3, and they're free to families who qualify. Getting an evaluation doesn't commit you to anything and it doesn't label your child. It just gives you information.

Does bilingualism cause speech delay?

No, and this is one of the most stubborn myths in early childhood development. Bilingual children develop language on the same overall timeline as monolingual children once you count vocabulary across both languages together. ^[7] A 24-month-old using 30 words in English and 25 in Spanish has a total expressive vocabulary of at least 55 words, which sits comfortably in the typical range.

What bilingual kids do show is language mixing, switching between languages within a sentence, and that's normal and expected. They may also have smaller vocabularies in each individual language than a monolingual peer for a while, simply because the same amount of input gets divided between two languages. Neither pattern signals delay.

If a bilingual child's vocabulary is below expectations even when you add both languages together, or if any red flags show up, get an evaluation. A bilingual speech-language pathologist is the best choice when you can find one, since tools normed only on monolingual children can give misleading results.

How does screen time affect when a toddler starts talking?

The AAP recommends no screen use for children under 18 months except video chatting, and no more than an hour a day of high-quality programming for ages 2 to 5, watched alongside a caregiver who talks with the child about it. ^[8] The logic is straightforward: language grows out of back-and-forth exchanges with responsive people, and screens don't respond, don't adjust to a child's level, and don't give the kind of feedback that builds communication.

Research on background television found that adult-directed TV playing in the background reduces parent-child talk and child vocalizations, even when the child isn't watching it directly. ^[9] It appears to work by cutting down the number of conversational turns between parent and child.

None of this means every minute in front of a screen harms language. It means screen time displaces time that could go toward interaction, and interaction is what actually builds language. If your child watches more TV than the guidelines suggest, the useful question isn't whether to feel guilty about it. It's which daily routines, bath time, meals, the car, the grocery store, could carry more conversation.

What can parents do at home to support speech development?

The strategies with the strongest evidence behind them are low-tech, free, and work whether your child is a typical talker or a late one. You can start today.

Talk through your routines. Narrate what's happening during diaper changes, meals, bath time, not as a running monologue but as conversation pitched at your child's level: "Soap. We're washing your hands. There's the water."

Follow your child's lead. If they pick up a ball, talk about the ball. Kids learn words fastest for things they're already looking at; trying to steer their attention toward something you'd rather name just slows things down.

Pause and wait. After asking a question or naming something, give your child 5 to 10 full seconds before you jump in. That silence feels awkward to most parents, but it's one of the most evidence-backed moves speech-language pathologists teach.

Expand rather than correct. If your child says "more," respond with "more crackers." If they say "doggie go," say "yes, the dog is going outside." You're modeling the next step without correcting them, which keeps things warm and teaches grammar along the way.

Read together daily. Shared book reading doubles as vocabulary instruction: point to pictures, name them, let your child set the pace. With younger toddlers it's fine to skip pages or reread the same favorite over and over.

For families wanting structured support at home, alongside or between therapy sessions, tools like Little Words offer guided activities built around a child's specific communication level. It's not a substitute for an SLP, but for families on a waitlist or practicing between sessions, a structured supplement can help.

What actually moves the needle for late talkers isn't complicated: more responsive interaction, more talk directed at the child, more back-and-forth. The hard part is keeping it up for months and years, not the techniques themselves.

When should I ask for a speech evaluation, and what happens during one?

Ask for a referral any time your child misses a milestone, any time your gut says something's off, or any time you're worried enough to be reading an article like this one. You don't need a diagnosis first, and you don't need your pediatrician to share your concern. In most states you can self-refer directly to a speech-language pathologist, or contact your local early intervention program yourself if your child is under 3. ^[2]

For children under 36 months, the starting point is usually early intervention through your state's IDEA Part C program. You call or email, they schedule a free evaluation, and if your child qualifies, they provide services. Federal law requires that evaluation to happen within 45 days of referral. ^[10]

During the evaluation, the SLP will typically watch your child play, run standardized tasks measuring vocabulary and comprehension, ask you detailed questions about your child's history and daily communication, and check oral motor function. The whole visit usually runs 60 to 90 minutes. Afterward, the SLP writes up a report comparing your child's current levels to age expectations and, if needed, recommends a frequency and type of therapy.

A full hearing test should happen before or alongside the speech evaluation if it hasn't already. Hearing loss is one of the most common, and most treatable, causes of speech delay, and it's not something parents or standard pediatric screenings can reliably catch on their own.

Online speech therapy is now widely available, and studies have found it produces outcomes equivalent to in-person therapy for many speech and language goals in children. For families in rural areas or stuck on long waiting lists, it's a legitimate option, not a fallback.

What happens if a toddler does not get help for a speech delay?

Honestly, it depends on the cause and severity, and nobody can promise you a specific outcome for your child.

For the roughly half of late talkers who turn out to be late bloomers, things generally go fine without intervention. Studies following these kids into school age find most show typical or near-typical language by age 5 to 6. ^[4]

For children whose delays come from an underlying language disorder, going untreated is linked to later reading difficulties, weaker academic performance, and social-emotional struggles in school. Research on language-impaired children found that unresolved early language problems track with higher rates of reading disorder and lower achievement compared to peers who got help. ^[11]

For children with autism, the evidence for early intensive intervention is among the strongest in developmental pediatrics: intervention started before age 3 consistently produces better communication and adaptive outcomes than intervention started later. ASHA describes early intervention as taking "advantage of brain plasticity during a critical developmental period." ^[1]

Here's the cleanest way to think about it: getting an evaluation and learning your child doesn't need therapy costs you a few hours. Skipping it, and finding out at kindergarten that your child needed help all along, costs your child years of easier learning.

Are boys really slower to talk than girls?

There's a real but small average difference. Population studies find boys are somewhat more likely to be late talkers than girls, with estimated rates around 13 to 17 percent of boys versus 8 to 10 percent of girls in the toddler years. ^[4] Boys are also diagnosed with developmental language disorder more often.

The key word there is average. The overlap between boys' and girls' language development is huge. A boy on track at 18 months doesn't get a pass at 24 months just because he's a boy, and a girl who's behind at 18 months doesn't warrant extra scrutiny just because most girls talk earlier.

So the practical takeaway is narrow: being a boy is a mild risk factor that might reasonably shape how closely a pediatrician watches things, but it's not a reason to wait and see once a child is actually missing milestones. The same thresholds apply to everyone.

Toddler talking: common questions, answered plainly

Most kids say a real first word somewhere between 10 and 14 months, and pediatric guidelines expect at least one to three consistent, meaningful words by the first birthday. Babbling, gestures like pointing and waving, and reliably responding to their name should also be showing up by then. If none of that is happening at 12 months, don't wait for the next scheduled checkup: mention it to your pediatrician now.

By 24 months, the expectation shifts to at least 50 words plus early two-word combinations like "more juice" or "daddy go." A child with far fewer words, or who isn't combining any yet, meets the clinical definition of a late talker and should get a speech-language evaluation. Somewhere between 15 and 20 percent of 2-year-olds fall into this group, so it's common, but there's no upside to waiting it out.

A toddler who understands everything but says little is a bit of a different story. Strong comprehension with limited speech is often called an expressive-only delay, and some children close the gap on their own. Still, since there's no way to know in advance who will catch up, it's worth getting evaluated anyway. The evaluation itself carries no real downside: either it puts your mind at ease or it connects your child with help.

At 12 months specifically, one to three real words is typical, things like "mama," "dada," "no," "hi," "uh-oh," or a name for a favorite object or person. The exact words matter far less than whether they're used on purpose and consistently; babbling that just sounds word-like without real meaning doesn't count toward that total.

At 18 months, guidelines call for at least 10 words, though some sources put the floor a bit lower, around 5 to 10. Fewer than 10 consistent words at this age is below the expected range and worth having checked. A bigger warning sign, though, is losing words a child used to say. If that happens, call your pediatrician that week rather than waiting.

Screen time itself doesn't directly cause a lasting speech delay, but it does eat into the back-and-forth interaction that actually builds language, and background TV has been shown to cut down on parent-child conversation even when a child isn't actively watching it. The AAP recommends no screens besides video chat before 18 months, and for ages 2 to 5, no more than an hour a day of quality programming watched together with a parent.

Bilingualism doesn't slow language development either. When you count vocabulary across both languages, bilingual children track the same overall timeline as monolingual kids: a 2-year-old with 30 words in one language and 25 in another has a combined 55 words, which is well within typical range. If a bilingual child's combined total falls short or other red flags show up, the most accurate read comes from evaluation by a bilingual speech-language pathologist.

Getting an evaluation costs nothing for children under 3 in the U.S.: your state's early intervention program, run under IDEA Part C, provides it free. You can contact the program directly yourself, no doctor's referral required, though your pediatrician can also start the process. By federal law, the evaluation has to happen within 45 days of referral, and services after that are free or low-cost depending on family income. Early intervention itself is the broader federal program for children under 3, covering things like speech-language therapy, occupational therapy, and developmental instruction; speech therapy is just one piece of it. After age 3, kids move into school-based services under IDEA Part B, and families can also pursue private speech therapy at any age, whether or not they've gone through early intervention.

Speech delays show up often in autism, but most toddlers with a speech delay don't have autism. Clinicians tend to look more closely at autism when a speech delay comes with other signs: not responding to their name, little eye contact, reduced social smiling, very limited pointing or gesturing, or repetitive behaviors. The AAP recommends autism-specific screening at the 18- and 24-month checkups regardless of whether a parent has raised concerns.

Echolalia, repeating words or phrases heard from someone else or from media, either right away or after some delay, is a normal part of language development before about age 2.5. If a child's communication stays mostly or entirely echolalic past that age, without much spontaneous functional language, that's worth bringing to a speech-language pathologist. It shows up often in autism and in some children with language processing differences, but it doesn't mean a child can't learn to communicate.

As for how understandable a toddler should be to others, a rough clinical benchmark is that familiar adults understand about 50 percent of a 2-year-old's speech, 75 percent of a 3-year-old's, and all of a 4-year-old's; strangers understand somewhat less. If a stranger struggles to follow most of what a 4-year-old says even with context, an articulation or phonological evaluation makes sense. Parents usually understand their own child better than these numbers suggest, which is exactly why an outside opinion is useful.

Finally, the slower, higher-pitched, more repetitive way adults naturally talk to babies (sometimes called child-directed speech) genuinely helps language development; research shows it helps infants pick up on the sounds of their language. What doesn't help is dumbing down vocabulary or deliberately mispronouncing words over time. A good rule of thumb is to match your child's current level and then stretch just one step beyond it: if they're using single words, respond with simple two-word phrases.
