TL;DR
Most toddlers say their first real word between 10 and 14 months, reach 50 words by 24 months, and start combining two words around 18 to 24 months. Missing these markers doesn't always mean something is wrong, but it does mean you should talk to a pediatrician or speech-language pathologist. Early help makes a measurable difference.
What age should a toddler start talking?
The short answer: most children say their first recognizable word somewhere between 10 and 14 months [1]. That window is wider in real life than it looks on a milestone chart. Some kids say "mama" at 9 months and mean it. Others don't land a clear first word until 15 or 16 months and then take off.
The American Academy of Pediatrics uses 12 months as the benchmark age to expect a first word, and by 16 months they expect at least a handful of single words in regular use [2]. The American Speech-Language-Hearing Association (ASHA) puts the typical range for first words at 10 to 15 months, with the understanding that a child who hits 16 months with no words at all should be evaluated [3].
What counts as a "word"? A speech-language pathologist counts a word when a child uses the same sound or approximation consistently and on purpose to mean the same thing. "Ba" for ball, said every time the child sees a ball, counts. Random babble doesn't.
Here's the piece most milestone charts skip: talking sits on top of communication skills that start months earlier. Babies who make eye contact, respond to their name, point, wave, and babble in back-and-forth exchanges by 9 to 12 months are on track for speech even before that first word arrives [2]. If those pre-language skills are missing, that matters more than the exact date of the first word.
What are the speech and language milestones from birth to age 3?
The table below pulls typical ranges from the CDC's developmental milestones and ASHA guidance. These are population averages, not pass/fail cutoffs.
| Age | Typical speech and language skills |
|---|---|
| 2 months | Coos, reacts to sounds |
| 4 months | Babbles, laughs, imitates some sounds |
| 6 months | Babbles chains ("bababa"), responds to name |
| 9 months | Uses varied babble, gestures (waves, reaches), points |
| 12 months | 1 to 3 words with meaning, imitates sounds, responds to simple requests |
| 15 months | 3 to 5 words, uses gestures + words together |
| 18 months | 10 to 25 words, can point to body parts when named |
| 24 months | 50+ words, starting to combine two words ("more milk", "daddy go") |
| 30 months | 200+ words, mostly two-word phrases, strangers understand about half of speech |
| 36 months | 200 to 1,000 words, three-word sentences, strangers understand most of speech |
Sources: CDC developmental milestones [4], ASHA typical speech and language development [3].
Two numbers are worth memorizing: 50 words by 24 months, and word combinations by 24 months. Those two markers together are the most consistent predictors researchers have for telling apart children who will need support from those who catch up on their own [5].
A child who has 50 words but isn't combining them yet at 24 months sits in an ambiguous zone. A child who has neither is very likely to benefit from early evaluation. That's not a diagnosis. It's just how the research shakes out [5].
What's the difference between a late talker and a language delay?
Parents hear these terms mixed up constantly, including by some pediatricians, so let's be clear.
A late talker is a child, usually between 18 and 30 months, who has fewer words than expected but whose understanding of language, play skills, and social development all look age-appropriate. Somewhere between 10 and 20 percent of toddlers are late talkers by this definition [5]. About half of them catch up without formal therapy, which is where the old "wait and see" advice came from.
A language delay is broader. It means a child's expressive language (talking) or receptive language (understanding) or both are significantly behind age expectations. A language delay can exist alone or alongside other conditions like autism spectrum disorder, childhood apraxia of speech, or hearing loss.
The distinction matters for treatment decisions, but here's the honest clinical reality: you often can't tell from a quick office visit which category a toddler falls into. An evaluation by a speech-language pathologist is the way to find out. Research keeps showing that children who get early intervention services by age 3 have better long-term outcomes than those who wait, even when the eventual diagnosis turns out to be mild [6].
If your child is a late talker with good social engagement and solid comprehension, watchful waiting with monthly check-ins might be reasonable. If comprehension is also behind, or if there are social communication concerns, waiting is not the right call.
What are the red flags that a toddler has a speech delay?
The CDC and AAP both publish specific "act early" signs. These are the ones that should prompt a call to your pediatrician or a referral to a speech therapist without waiting for the next well-child visit [2] [4].
By 12 months:
- No babbling
- No gesturing (pointing, waving, reaching)
- No response to name
- No back-and-forth sounds or expressions with caregivers
By 16 months:
- No single words
By 24 months:
- Fewer than 50 words
- No two-word spontaneous phrases (not counting imitation)
- Strangers cannot understand any of the child's speech
By 36 months:
- Strangers cannot understand most of what the child says
- No three-word sentences
- No questions or comments in conversation
Two more red flags apply at any age: losing language skills the child used to have (called regression), and not following simple directions without gestures. Regression matters most. Words a child used to say but no longer does should be reported to a pediatrician promptly, because it can be linked to autism spectrum disorder and other neurological conditions [2].
If your child shows any of these, trust your gut and make the call. The downside of evaluating a child who turns out to be fine is zero.
Why isn't my toddler talking? What causes speech delays?
There's rarely a single clean answer, and parents often blame themselves when they did nothing wrong. Speech delays have many causes, and plenty of them overlap.
Hearing loss is the most commonly missed one. Somewhere between 1 and 3 in 1,000 newborns have significant hearing loss at birth, but mild or fluctuating hearing loss from chronic ear infections can develop later and go undetected for months [7]. A hearing test should be part of any speech evaluation.
Autism spectrum disorder often shows up first as a communication difference. Children with autism may have delayed speech, unusual speech patterns (see echolalia), or speech that develops and then regresses. About 1 in 36 children in the U.S. has been identified with ASD as of the CDC's 2023 data [8]. If you have concerns about social engagement alongside speech, ask for a developmental evaluation, more than a speech screening.
Childhood apraxia of speech is a motor speech disorder where the brain has trouble planning and sequencing the movements for speech. It's less common than general speech delay, and it gets misread as stubbornness or a "lazy" child. It needs specific, intensive therapy [9].
Other contributors include:
- Premature birth (preterm infants are at higher risk for all developmental delays)
- Family history of late talking or language disorders
- Bilingual or multilingual household (normal variation, not a delay, though assessments must account for it)
- Limited language exposure at home (though research suggests screen time alone is rarely the primary cause in otherwise healthy children)
- Intellectual disability
- Oral motor differences (tongue tie, low muscle tone in the mouth)
The point isn't to find something to blame. A proper evaluation identifies what's actually driving the delay so the right approach gets matched to the real problem.
How to get a toddler talking: what actually helps at home
Home practice doesn't replace a professional evaluation, but there's solid evidence that the way caregivers talk to and with their children changes language development. The research here is unusually consistent.
Talk more, and talk differently. Hart and Risley's 1995 work (and later replication studies) found that the number of words children hear from caregivers by age 3 predicts vocabulary and reading ability years later [10]. Quality matters as much as quantity. Narrating what you're doing ("I'm washing the dish now, see the bubbles?"), asking real questions you wait for answers to, and responding to every attempt your child makes to communicate all move the needle.
Follow their lead. If your toddler points at a dog, say "dog" or "big dog" or "the dog is running." Don't quiz them ("what's that?"). Expand on what they already care about.
Cut the questions, add comments. Parents instinctively fire off "what's that?" over and over. For a child who's struggling to talk, a steady stream of questions creates pressure. Commenting ("oh, a truck!") keeps the conversation open without demanding a response.
Get face-to-face. Toddlers learn speech by watching your mouth and reading your expression. Get down to their level.
Read together every day. Shared book reading at ages 1 to 3 is one of the most studied language-building activities there is, with measurable effects on vocabulary, grammar, and comprehension [10].
If you want structured daily activities built on these strategies, tools like the Little Words app are designed around caregiver-coaching principles and can help you track progress between therapy sessions.
None of this replaces a speech-language pathologist if your child needs one. Think of home strategies as the environment that supports whatever professional work is happening.
When should I be worried vs. when can I wait?
This is the question every parent actually wants answered, and the honest answer is: it depends on the combination of factors, not any single one.
You can afford to watch and wait (briefly) if:
- Your child is under 18 months, has a few words, and shows good social engagement and comprehension
- Your child is a bilingual toddler whose total word count across both languages meets expectations
- Your child had an ear infection recently and speech seems to have dipped temporarily
You should not wait if:
- Your child has lost words they previously used
- Your child is 16 months with no words at all
- Your child is 24 months with fewer than 50 words or no word combinations
- You have any concern about hearing
- Social communication looks different (limited eye contact, doesn't respond to name, doesn't point to share interest)
- Your gut has been telling you something is off for more than a month or two
The AAP recommends developmental surveillance at every well-child visit and formal developmental screening at 9, 18, and 30 months (or whenever a concern comes up) [2]. You don't need a scheduled visit to raise a concern. You can call your pediatrician today and ask for a speech and language referral. In many states, you can also self-refer to your state's early intervention program for children under 3 without a doctor's referral.
Early intervention services for children under 3 are guaranteed under the Individuals with Disabilities Education Act (IDEA), Part C. The statute says services must be provided "in natural environments" and at no cost to families for eligible children [6]. Eligibility criteria vary by state, so contact your state's Part C coordinator to find out what your child qualifies for.
How does a speech-language pathologist evaluate a toddler?
A lot of parents expect a toddler evaluation to look like a test. It mostly doesn't. A good pediatric speech-language pathologist spends most of the session watching the child play, talking with caregivers, and running the occasional structured play-based task.
The evaluation usually covers:
- Receptive language: does the child understand words, simple commands, questions?
- Expressive language: how many words does the child use, what types, any phrases?
- Speech sounds: are the sounds the child makes age-appropriate?
- Oral motor skills: does the mouth move normally for eating and speech?
- Social communication: does the child use language to interact, more than to label?
- Hearing screening or referral: often done first, because everything else depends on it
Standardized tests like the Preschool Language Scales (PLS-5) or the Receptive-Expressive Emergent Language Test (REEL-4) give scores that compare a child to age peers [3]. Standardized scores alone don't tell the whole story. A good evaluator also watches how the child communicates in real interaction.
After the evaluation, the SLP should give you a written report with scores, a plain-English interpretation, and specific recommendations. If therapy is recommended, ask how often, what approach they'll use, and what you can do at home between sessions. If autism spectrum speech therapy or apraxia of speech is suspected, the treatment approach is meaningfully different from general language delay therapy, and you want a clinician who knows that distinction.
Does being bilingual delay speech? What parents of multilingual kids need to know
This question comes up constantly, and the short answer is no. Bilingualism does not cause speech or language delay.
Bilingual children may have a smaller vocabulary in each single language than monolingual peers, but when you count words across both languages (total concept vocabulary), they're typically right on track [3]. A bilingual child should still meet the core milestones: first words by 12 to 15 months, 50 total words (across both languages) by 24 months, and two-word combinations by 24 months.
If a bilingual child is delayed in both languages, that's a real concern and warrants evaluation. If they seem to be catching up in the home language but not yet in the second language, that's more likely a second-language learning pattern than a disorder.
Evaluations for bilingual children should be done in both languages whenever possible. Assessing only in English overestimates the degree of delay and can lead to unnecessary diagnoses. Ask specifically whether your evaluator has experience with bilingual assessment, and request interpreters or bilingual SLPs if available [3].
What happens in speech therapy for toddlers, and does it work?
Speech therapy for toddlers looks like play. That's on purpose. Young children don't learn through drills. They learn through meaningful interaction and repetition folded into things they care about.
A session with a toddler might mean building with blocks while the therapist models words, playing pretend kitchen to target two-word phrases, or using bubbles and balloons to pull out specific sounds. Parents are more and more part of sessions now, because caregiver-coaching models (where the therapist teaches the parent the techniques and the parent practices with the child) have strong evidence behind them, especially for children under 3 [5].
Does it work? For most children and most types of delay, early speech therapy produces measurable gains. A 2019 Cochrane review found that speech and language therapy for children with primary language delay is effective, particularly for vocabulary and expressive language [5]. The evidence is strongest when therapy starts early, involves caregivers, and happens often enough (most SLPs recommend at least once a week for moderate delays).
For children with specific diagnoses like childhood apraxia of speech, more intensive and specialized approaches are needed. For children whose delays are part of autism, Naturalistic Developmental Behavioral Interventions (NDBIs) have the most consistent evidence base [8].
For children who aren't talking yet or who have very limited speech, AAC devices (picture boards, speech-generating apps) may be introduced alongside speech therapy. There is no credible evidence that AAC use slows speech development. The evidence actually points the other way [3].
How to get a speech therapy referral and access early intervention services
Start with your pediatrician. Ask specifically for a referral to a speech-language pathologist, or for a referral to your state's early intervention program if your child is under 3. Some pediatricians still default to "let's wait and see." If you've read this far and your child is missing milestones, you don't have to wait. Push back and ask for the referral anyway.
Under IDEA Part C, every state has a publicly funded early intervention system for children from birth to age 3 [6]. You can often self-refer by calling the program directly without going through your doctor. The CDC's "Learn the Signs. Act Early." program can help you find your state's contact [4].
For children age 3 and older, services shift to the school system under IDEA Part B. Your local school district is required to evaluate your child for free if you request it in writing.
Private speech therapy is also an option, though cost and insurance coverage vary a lot. Many insurance plans cover speech therapy for developmental delays, but authorization requirements differ. Ask your insurer specifically whether pediatric speech therapy for developmental (not accident-related) delays is covered under your plan.
If you want tools to support your child at home while you wait for an evaluation or between therapy sessions, Little Words has a free quiz to help identify where your child is and what strategies match their profile.
Frequently asked questions
At what age should a toddler start talking in sentences?
Most toddlers start combining two words into short phrases ("more juice," "daddy go") between 18 and 24 months. Three-word sentences typically appear between 24 and 36 months. If a child has no two-word combinations by 24 months, that's a flag worth bringing to a speech-language pathologist regardless of single-word vocabulary size.
Is it normal for a 2-year-old not to be talking?
A 2-year-old with no words at all, or fewer than 50 words and no word combinations, is outside the typical range. The AAP and ASHA both recommend evaluation by this point. That doesn't mean something is seriously wrong, but "wait and see" past age 2 with no words is not what the evidence supports. Get the evaluation and go from there.
What is the difference between a speech delay and a language delay?
Speech delay refers to difficulty producing sounds and words clearly. Language delay means the child isn't developing the vocabulary, grammar, or understanding of language at the expected rate, regardless of how clearly they speak. A child can have one without the other. Both are evaluated by a speech-language pathologist, but the treatment approaches differ.
Can screen time cause a speech delay?
Heavy screen time is associated with reduced language interaction, which matters for development. The AAP recommends no screen time except video calls for children under 18 months, and limited, high-quality content for ages 18 to 24 months. But screen time alone is rarely the single cause of significant delay. If your child is missing milestones, get an evaluation rather than just cutting screens.
How many words should a 18-month-old say?
Typical range at 18 months is 10 to 25 words. The AAP uses 5 words as a low threshold for concern at this age. If your 18-month-old has fewer than 5 to 10 words, or has words but uses them inconsistently, bring it up at the next well-child visit or call earlier. Many SLPs use 15 words by 18 months as the practical benchmark for typical progress.
Does my toddler need speech therapy or will they just catch up on their own?
About half of late talkers with good comprehension and social skills do catch up without therapy. The problem is you can't reliably predict which half your child is in without evaluation. Children who also have comprehension gaps, social communication differences, or a family history of language disorders are much less likely to catch up on their own. An evaluation gives you real information instead of a coin flip.
What's the earliest age you can start speech therapy?
There's no minimum age. Early intervention services under IDEA Part C cover children from birth through age 2, and SLPs work with infants who have feeding or early communication concerns. For toddlers with speech delay, most clinicians are comfortable starting evaluation and therapy at 18 months or even earlier if red flags are present. Earlier referral consistently produces better outcomes.
Can boys really be late talkers more than girls?
Boys are diagnosed with speech and language delays roughly twice as often as girls, though the reasons aren't fully understood and may involve diagnostic differences as much as developmental ones. Being a boy doesn't lower the threshold for when you should seek evaluation. The same milestone benchmarks apply regardless of sex, and boys who are delayed benefit from early therapy just as girls do.
How do I get my toddler to start talking if they're behind?
The most evidence-backed home strategies are: narrate your daily activities out loud, follow your child's interests and comment on what they're looking at, reduce yes/no questions in favor of open comments, read together every day, and respond enthusiastically to every communication attempt even if it's not a word yet. These strategies support therapy but don't replace evaluation if milestones are being missed.
What if my toddler was talking and then stopped?
Losing words a child previously used, called regression, should be reported to your pediatrician right away. It's one of the early signs associated with autism spectrum disorder, though it can have other causes. Don't wait for the next scheduled appointment. A regression of even a few words is worth a prompt call and usually triggers a developmental evaluation.
How does echolalia relate to toddler speech development?
Echolalia, repeating words or phrases heard elsewhere, is a normal stage in early language development. When it persists as the main form of communication past age 3, or when it appears alongside other social communication differences, it may be associated with autism spectrum disorder. A speech-language pathologist can assess whether a child's echolalia is developmental or part of a larger pattern that needs support.
Is online speech therapy effective for toddlers?
Telehealth speech therapy has grown significantly and the research on it is generally positive for school-age children. For toddlers specifically, the evidence is thinner, though caregiver-coaching models where the parent is trained and then works with the child directly may actually be well-suited to a remote format. It's worth considering when in-person services aren't accessible, but ask your SLP whether the format fits your child's specific needs.
