25 month old speech milestones: what's typical and when to act

By 25 months, most toddlers have at least 50 words and are regularly putting two of them together, things like "more milk" or "daddy go." Three-word combinations tend to show up a bit later, around 27 months. If your child has fewer than 50 words, isn't combining words yet, or you just have a nagging feeling that something's off, that's enough reason to ask for an evaluation now rather than waiting for the next well-child visit.

What speech milestones should a 25 month old have?

At this age, you're looking for a vocabulary of at least 50 words, regular two-word phrases, and new words appearing every week or two. That's the short version.

The American Speech-Language-Hearing Association (ASHA) describes typical 2-year-olds as having a vocabulary of at least 50 words and beginning to combine two words together ^[1]. At 25 months your child is one month past the second-birthday benchmark, so the 24-month targets still apply. Two-word combinations at this age shouldn't be occasional accidents. They should be a regular, spontaneous habit: "big dog," "no bed," "want cracker." Hear those pairings a few times a day and that's a good sign.

Word count matters, but variety matters just as much. Research by Fenson and colleagues, the team behind the MacArthur-Bates Communicative Development Inventories (CDI), found typically developing 24-month-olds produce a median of around 300 words, with the 10th percentile sitting near 50 words ^[2]. That 50-word floor is the clinical concern line, not the average: most kids at 25 months clear it easily. If your child is sitting right near that number, it's worth a closer look.

Understanding runs ahead of talking at every age. A 25-month-old should follow two-step directions ("Get your shoes and put them by the door"), understand simple questions, and point to named pictures in a book. If comprehension is lagging too, that matters more than a low word count on its own.

What new skills appear between 25 and 27 months?

A lot happens in this stretch. Two-word phrases get steadier and start to cover more ground. Early on, most combinations are demands, like "more juice." By 26 or 27 months, you start hearing relational language too: "daddy shoe," "doggy sleeping," "that mine." The grammar is still bare-bones, but the range of things a child can express grows fast.

Around 27 months, early three-word phrases show up for a lot of kids. The AAP's milestone checklists, revised in 2022 with input from experts including ASHA, list three-word sentences as expected around 30 months, so plenty of children try them out a few months ahead of that ^[3]. A 27-month-old who occasionally says "I want that" or "more banana please" is ahead of the median, not behind it.

Conversational back-and-forth also picks up around this age. A typically developing 27-month-old can usually keep an exchange going for two or three turns on a topic they actually care about. That's a separate skill from how many words a child knows, and it tells you a lot about where language is headed.

At 26 months, most of what held true at 25 months still applies. What matters now is whether two-word combinations have become the child's default way of talking instead of something they do occasionally. If word combinations are still rare or absent at 26 months, that's worth raising with your pediatrician now rather than waiting for the 30-month visit.

By 27 months the bar moves up a bit. A child who's still mostly using single words, or whose vocabulary growth has stalled, should get a speech-language evaluation. There's no benefit to waiting and seeing if more time passes first.

How many words should a 25 month old say?

Fifty words is the clinical floor, but most kids at 25 months say a lot more than that.

The MacArthur-Bates CDI normative data puts the median expressive vocabulary at 24 months near 300 words for girls and slightly lower for boys, with wide variation inside the normal range ^[2]. In practical terms, a child with 50 to 100 words at 25 months is technically in range but sitting toward the low end. What worries me more than any single word count is a plateau, or a downward trend in how many new words show up.

One thing that trips up a lot of parents: only count words your child uses on their own, with meaning behind them. Animal sounds like "moo" or "woof" count if they're used consistently to mean the animal. Words your child only echoes right back after you say them usually don't count toward functional vocabulary. If a big chunk of what you're counting is immediate imitation or scripted phrases, mention that to a clinician even if the raw number looks fine. Our article on echolalia explains what echoed speech means developmentally.

A rule of thumb from clinical practice: at this age, new words should keep arriving at a steady clip. A vocabulary stuck at roughly the same size for six weeks or more is a signal, not a coincidence.

What counts as a speech delay at 25 months?

A language delay isn't one cutoff. It's a profile, and a few specific signs are what ASHA and the AAP treat as reasons to get a referral at this age: fewer than 50 words, no two-word combinations yet, trouble following simple two-step instructions, loss of words or skills the child used to have, and being understood by familiar adults less than half the time ^[1][3].

Loss of skills deserves its own mention, separate from the rest. If your child had words and then stopped using them, that's a different situation from being a late talker, and it's worth calling the pediatrician right away rather than waiting to see what happens.

There's a real difference between a "late talker" (few words, but strong understanding and social engagement) and a language delay that touches several areas of communication at once. Late talkers sometimes catch up on their own, though the evidence on how often that happens is murkier than most parents are told. A 2019 review in the Journal of Speech, Language, and Hearing Research found that a meaningful share of children who were late talkers at age 2 still showed language differences once they reached school age, which is part of why clinicians tend to push for an early evaluation instead of waiting ^[4].

If you genuinely can't tell whether your child is simply a late talker or dealing with something bigger, an evaluation by a certified speech-language pathologist (CCC-SLP) is really the only way to know for sure. A pediatrician's screening tool has its place, but it isn't a substitute for that.

What causes speech delays in 2-year-olds?

There's rarely one single cause, and for a lot of kids with speech delays, no specific cause turns up even after a full workup.

Hearing loss is the first thing clinicians rule out, and for good reason. Even mild, on-and-off hearing loss from repeated ear infections cuts into how much language a child hears clearly during the years when the brain is most ready to absorb it. If your child hasn't had a formal audiology evaluation yet, that step usually happens before or alongside the speech-language evaluation ^[3].

Developmental language disorder (DLD) is the most common diagnosed cause of language delays that stick around. There's no single known cause of it, and it isn't caused by parenting or screen time, though those things do influence how much rich language a child gets exposed to.

Autism often comes with speech and language differences, though the picture looks different from kid to kid. Some autistic toddlers at 25 months have large vocabularies but communicate in unusual ways. Others have significant trouble producing language at all. An autism evaluation and a speech-language evaluation work together rather than competing for an answer, and our piece on autism spectrum speech therapy goes deeper into what therapy looks like for autistic children. Childhood apraxia of speech (CAS) is a motor speech disorder, meaning the brain has trouble planning the movements needed to produce speech. It's fairly rare, but worth knowing about because it needs a different kind of therapy than a language delay does. If your child seems to struggle physically to get words out, has speech that's wildly inconsistent, or had words at one point and then lost them, apraxia belongs on the list of things to rule out. Our article on childhood apraxia of speech breaks it down further.

Bilingual exposure gets blamed for delays, but that's not accurate. Kids learning two languages at once may have somewhat smaller vocabularies in each individual language, but their combined vocabulary across both is typically in line with monolingual peers ^[5]. A child growing up bilingual who isn't hitting milestones in either language still needs an evaluation.

Should I be worried if my 25 month old isn't combining words yet?

Yes, and this is one of those situations where waiting to see what happens is the wrong move.

Both ASHA and the AAP place two-word combinations at 24 months ^[1][3]. So at 25 months, if your child isn't putting words together at all, you're already a month beyond when that skill should show up. That doesn't automatically mean something's wrong with your child. But it does mean this is worth getting checked now, rather than mentioning it at the 30-month checkup.

Worth knowing: early intervention for children under 3 is federally funded in the US under Part C of IDEA, so evaluations and services for kids who qualify cost families nothing ^[6]. You can start this through your pediatrician, or by calling your state's early intervention program on your own. No diagnosis is required just to get an evaluation.

The most useful thing you can do today is ask for a referral to a speech-language pathologist, or pick up the phone and contact your state's early intervention program directly. Either route gets your child evaluated. If you wait for a well-child visit that may not happen until 30 months, that's weeks of possible therapy time gone for good.

What does speech therapy look like for a 25 month old, and does it work?

At this age, therapy doesn't look like drills. It looks like play.

A speech-language pathologist working with a 25-month-old typically follows the child's lead, building chances to communicate into play and teaching parents strategies to use at home every day. The clinician might work on getting the child to request items, comment on what's happening, imitate words, or stretch from one-word to two-word phrases. Most of the real progress happens in the hours between sessions, when parents keep using the same techniques.

Does it work? The evidence for early intervention in toddlers is generally positive, though the picture has some nuance. A Cochrane review of therapy for young children with speech and language disorders found moderate-quality evidence that parent-implemented interventions increase expressive vocabulary ^[7]. The earlier therapy starts, the more of it lands during the years when the brain is most plastic.

Kids with a specific diagnosis like CAS need therapy that's frequent and tightly structured. Late talkers without other concerns tend to do well with parent-coaching models, often paired with direct therapy. If you want the fuller picture on evaluations and the different ways services get delivered, our overview of speech therapy walks through it.

Families stuck on waitlists or without local providers nearby have another option: online speech therapy has grown a lot, and the evidence for young children is reasonably strong, especially when a parent stays in the session and stays active in it.

What can parents do at home to support speech development at this age?

The research on what actually helps at home is pretty consistent, and none of it requires special materials.

Self-talk and parallel talk are two of the most studied techniques. Self-talk means narrating what you're doing out loud ("I'm washing the cup. Now I'm drying it."). Parallel talk means narrating what your child is doing ("You're pushing the car. It's going fast."). Both give your child a steady stream of language without asking them to perform.

Expansion is the move speech-language pathologists teach parents again and again. Your child says something, and you repeat it back with one piece added. Child says "ball," you say "big ball" or "throw ball." Child says "more," you say "more crackers?" This kind of recasting hands your child a slightly richer model at the exact moment they're already trying to communicate.

Cutting back on questions and leaning into comments surprises a lot of people. Quizzing your child ("What's that? What color is it? What does it say?") tends to pull less language out of them than simply commenting alongside what they're doing. Questions put a child on the spot. Comments invite shared attention instead. Shift your ratio toward observations and see what happens.

It also helps to cut background noise and screens during the times you're actively talking with your child. The AAP recommends avoiding digital media for children under 18 to 24 months (video chatting aside) and staying present and engaged when older toddlers do use media ^[8]. Screens aren't the enemy on their own. The issue is that background TV eats into the amount of child-directed speech a child actually hears.

If you'd like more structure for working these strategies into daily routines, the Little Words app has parent-coaching exercises built for late talkers and neurodivergent toddlers, and the start quiz can point you to activities that match where your child is right now.

One thing I'll say straight: consistency beats intensity. Twenty minutes of real back-and-forth during bath time, meals, and getting dressed does more than one concentrated "speech session" a week.

What's the difference between a late talker and a language disorder?

Late talker is a description, not a diagnosis. It refers to a child whose expressive vocabulary lags behind expectations while comprehension, play skills, and social engagement stay on track. Slow to start, but the foundations are there.

A language disorder (often developmental language disorder, or DLD) is different: it involves trouble with language processing, comprehension, or both, and it tends to stick around past the early years. A child with DLD might struggle with grammar, following complex directions, or telling a story that actually hangs together, even once their vocabulary has grown.

Here's the catch: at 25 months, telling a late talker apart from a child with an emerging language disorder is genuinely hard. That's exactly why evaluation matters more than labeling. A speech-language pathologist looks at the whole communication picture, not just word count, and that's what shapes the plan going forward.

Worth knowing: even kids who catch up expressively sometimes carry subtle language differences into school age, showing up later in reading comprehension or storytelling. That's part of why getting an early evaluation pays off, even when a child eventually catches up.

How is a 25 month old's speech evaluated?

A full speech-language evaluation at this age looks at what the child says, what they understand, how they produce speech sounds, and how they use communication in social situations. It's a broader picture than just counting words.

Clinicians typically use standardized assessments normed for toddlers, such as the Preschool Language Scales (PLS-5) or the Receptive-Expressive Emergent Language Test (REEL-4), though which one gets used depends on the clinician's judgment about what fits the child in front of them. A detailed parent interview is also part of the process, and it matters more than people expect: you see your child across far more settings than any clinician catches in a single session.

If you're going through federally funded early intervention under IDEA Part C, the evaluation has to happen within 45 days of referral ^[6], and it's free through that system. A private evaluation with an SLP outside early intervention may be covered by insurance depending on your plan, so it's worth checking whether yours requires a physician referral first.

When the evaluation turns up an eligible delay or disorder, the team puts together an Individualized Family Service Plan (IFSP), which spells out the goals and services for both the child and the family. Parents help build this plan alongside the team rather than simply receiving a finished document.

When should I call the pediatrician or request a referral?

Call if your 25-month-old has fewer than 50 words, isn't combining two words yet, has lost words or skills they once had, struggles to understand simple instructions, or if you just have a strong feeling something's off with their communication, even when the word count seems fine.

The AAP recommends developmental surveillance at every well-child visit and formal developmental screening at 9, 18, and 30 months, with autism-specific screening at 18 and 24 months ^[3]. Screening isn't the same thing as a full evaluation, though. Passing a screen doesn't mean your child's speech is on track if you're already noticing red flags.

You don't need your pediatrician's sign-off to reach out to your state's early intervention program either; you can self-refer directly. The CDC keeps contact information for every state's EI program ^[9]. There's really no downside to making the call: an evaluation either tells you your child is on track, which is a relief, or it catches something early enough to actually do something about it.

Worth knowing: SLP waitlists run long in a lot of areas right now. Starting a referral early, even before you're sure there's a real problem, gets your child seen sooner than if you wait until you're fully convinced something's wrong.

Frequently asked questions

What words should a 25 month old be saying?

By 25 months, a child should have at least 50 words they use on their own, with meaning. The pronunciation doesn't need to be perfect, but a familiar adult should understand most of what they say. You'd expect a mix of nouns, action words like go, eat, and want, social words like hi, no, and more, and a few describing words. Words that are only echoed back or only used in one narrow situation don't really count toward that 50-word total.

Is it normal for a 26 month old to not be talking much?

It depends what "not much" means. If it means fewer than 50 words or no two-word combinations, that falls outside the expected range at 26 months. Both ASHA and the AAP list two-word combinations as an expected skill by 24 months, so absent or very rare combinations at 26 months are a reason to see a speech-language pathologist. Some kids in this situation do catch up on their own, but the better move is to get an evaluation now instead of waiting a few more months to see what happens.

What are the speech milestones for a 27 month old?

A 27 month old on track will be combining two words consistently throughout the day, may be starting to try three-word phrases, and is understood by familiar adults most of the time. Vocabulary keeps expanding, and the child should be able to follow two-step directions and manage short back-and-forth conversations. If two-word combinations are still missing or inconsistent at this age, that's a clear signal to ask for a speech-language evaluation right away.

How many words should a 2 and a half year old have?

The AAP expects three-word sentences and a vocabulary well into the hundreds of words by 30 months. Somewhere between 25 and 27 months, on the way to 2.5, the 50-word floor set at the 24-month mark remains the line clinicians watch, but most typical children this age already have several hundred words. If your 2.5 year old is still sitting at or near 50 words, that's worth getting checked out.

Can a child with a speech delay catch up without therapy?

Some late talkers do catch up on their own, but fewer catch up completely than a lot of parents have been led to believe. A 2019 review in the Journal of Speech, Language, and Hearing Research found that a meaningful share of children who were late talkers at age 2 still showed language differences once they reached school age. Therapy improves outcomes, and starting early has no real downside. Waiting around for spontaneous catch-up, instead of getting an evaluation, uses up time during the years when the brain is most flexible.

Does watching TV cause speech delays?

Not in some direct, damaging way, but heavy background TV crowds out child-directed speech, which is what actually drives vocabulary growth. The AAP recommends no digital media at all for children under 18 to 24 months (aside from video chat), and for ages 2 to 5, no more than an hour a day of high-quality programming, watched with a parent. The real issue is lost interaction time, not screens themselves being harmful.

What is early intervention and how do I access it for my toddler?

Early intervention is a federally funded program, under Part C of IDEA, that provides developmental services to children under age 3 who have delays or disabilities. Services can include speech-language therapy, occupational therapy, and coaching for parents. For children who qualify, evaluations and services are free. You can refer your child yourself by reaching out to your state's early intervention program, or ask your pediatrician to make the referral. The CDC keeps a directory of state programs if you're not sure where to start.

How do I know if my toddler's unclear speech is a delay or just typical pronunciation?

Between 25 and 27 months, a child's speech should be understandable to familiar adults roughly half to three-quarters of the time. Strangers will understand even less, and that's fine. Mispronunciations are completely normal at this stage, since most speech sounds aren't fully mastered until somewhere between ages 4 and 7. What's worth worrying about isn't imperfect pronunciation. It's a child with very few words, no word combinations, or one who isn't understood by their own parents most of the time. A speech-language pathologist can tell you whether the sound errors you're hearing are typical or not.

Should I worry about echolalia in my 25 month old?

Repeating back what you just said is a normal part of how toddlers learn language. But if most of your child's communication is echoed rather than spontaneous, or they repeat scripts and phrases with no clear connection to the situation, that's worth bringing up with a speech-language pathologist. Echolalia can show up with autism, but it appears in other contexts too. Our article on echolalia meaning goes into more detail.

Does being bilingual cause speech delays?

No. Bilingual children may know fewer words in each individual language compared to monolingual peers, but their combined vocabulary across both languages is usually on par. A bilingual child who isn't hitting milestones in either language should still be evaluated, ideally by someone who assesses both languages rather than just one, since a single-language assessment can make a child look like they know less than they actually do.

What's the difference between a speech delay and a language delay?

Speech is the physical act of producing sounds. Language is understanding and using words, sentences, and meaning. A speech delay shows up as trouble with pronunciation or articulation, while a language delay shows up as trouble with vocabulary, grammar, or comprehension. Plenty of children have both, but they can occur separately. At 25 months, most of the clinical concern is around language, particularly vocabulary size and word combinations, though a thorough evaluation looks at both areas.

What therapies are available if my 25 month old is diagnosed with apraxia?

Childhood apraxia of speech calls for a motor-focused treatment approach rather than the usual language-stimulation model. Two evidence-based options are Dynamic Temporal and Tactile Cueing (DTTC) and Rapid Syllable Transition Treatment (ReST), both of which need frequent, intensive sessions. A diagnosis at this age is uncommon and requires a specialist evaluation, but catching it early matters because the treatment approach is so different from standard therapy. Our overview of childhood apraxia of speech covers this in more depth.

Can an app or technology support speech development at 25 months?

They can help, but as a supplement, not a replacement for human interaction or professional therapy. For toddlers under 3, the real language learning happens through back-and-forth exchanges with a responsive adult. That said, parent-coaching tools and guided activity apps can help parents keep up evidence-based strategies more consistently between therapy sessions. For a child with more complex communication needs, augmentative and alternative communication (AAC) devices might also come into the picture at this age.

Here's what the research actually says on this: by age 2, most kids have at least 50 words and are starting to put two words together, according to ASHA, Speech and Language Developmental Milestones. The MacArthur-Bates Communicative Development Inventories put the median expressive vocabulary at 24 months around 300 words, with the 10th percentile sitting closer to 50 (MacArthur-Bates Communicative Development Inventories (CDI), Norming Data). That's a huge range, and a later technical manual confirms just how much variation is normal at this age, with the median landing near 300 words for girls specifically (Fenson, L. et al. (2007). MacArthur-Bates Communicative Development Inventories User's Guide and Technical Manual, 2nd ed.). The AAP's 2022 milestones revision expects two-word combinations by 24 months and three-word sentences around 30 months, and it recommends ruling out hearing loss in any child with a speech delay (AAP, Developmental Milestones (2022 revision)). Familiar adults should be able to understand a 2-year-old about 50 to 75 percent of the time, and losing words a child already had is a red flag that warrants a prompt evaluation, not a wait-and-see approach (ASHA, Late Language Emergence Practice Portal). Raising a child in two languages doesn't put them behind: kids may have smaller vocabularies in each individual language, but their combined vocabulary across both typically matches monolingual peers (Hoff, E. et al. (2012). Developmental Science, 'Bilingual experience and language development in young children'). Still, being a late talker at 2 isn't something to shrug off entirely. Research published in the Journal of Speech, Language, and Hearing Research (published by ASHA) found that a meaningful share of late talkers still showed language differences once they reached school age. If you're wondering whether to act, the evidence is on the side of doing something rather than waiting. A 2018 Cochrane review found moderate-quality evidence that parent-implemented interventions help increase expressive vocabulary in late talkers (Cochrane, 'Speech and language therapy interventions for children with primary speech and/or language disorders' (2018)). And getting help is easier than many parents assume: under Part C of IDEA, eligible children under 3 can get early intervention services at no cost, with evaluations required within 45 days of referral (U.S. Department of Education, IDEA Part C Early Intervention Program). The CDC keeps a directory of state early intervention contacts if you want to self-refer (CDC, Learn the Signs Act Early). Worth mentioning too: screen time matters here. The AAP recommends no digital media for kids under 18 to 24 months (aside from video chatting) and capping screen time at one hour a day for ages 2 to 5 (AAP, Media and Young Minds Policy Statement (2016)).
