10-Minute Speech Practice That Doesn't Require Sitting Still

Last updated 2026-07-09

What should a 15 month old be saying?

At least one clear word, and ideally a handful, by the time your child hits the 15-month well-child visit. The American Academy of Pediatrics (AAP) surveillance checklist counts a "word" as any consistent sound your child uses to mean a specific thing, not textbook English. If your daughter says "ba" every time she sees her bottle and never for anything else, that counts ^[1].

Most children this age produce somewhere between 1 and 10 true words, and the normal range is wide. Norming data from the MacArthur-Bates Communicative Development Inventories puts the 50th-percentile 15-month-old at about 10 words, while children at the 10th percentile produce just 1 to 3 ^[2]. Both sit inside what most clinicians treat as watchful-waiting territory, depending on the rest of the picture.

Words matter. They aren't the whole story.

At 15 months, a typical toddler also:

• Points with one finger, both to request things and to show you something interesting
• Follows a simple one-step direction without a gesture cue, like "give me the ball"
• Understands about 50 words, even if they say far fewer ^[3]
• Uses varied sounds and intonation, not a flat, repetitive drone
• Makes eye contact and responds to their name consistently

If those social-communication pieces are missing, that matters more than a low word count by itself. A child who babbles constantly, points, and holds your gaze but says only two words is in a very different spot than one who is quiet, doesn't point, and doesn't track your eyes.

What are the actual red flags at 15 months?

The AAP's 2022 updated surveillance guidelines list specific 15-month milestones that call for immediate evaluation rather than more monitoring ^[1]. The hard stops:

• No single word used consistently (a general, non-specific "mama" or "dada" doesn't count)
• Not pointing to ask for something or to share interest
• Not walking (it signals broader developmental questions)
• Consistent failure to respond to their name

The American Speech-Language-Hearing Association (ASHA) adds that any loss of words a child already had, at any age, is an immediate red flag and never a wait-and-see ^[3].

Here's the one parents miss most. The absence of pointing is one of the strongest early signs of autism. A 2007 study in the Journal of Child Psychology and Psychiatry found that failure to point to share interest ("protodeclarative pointing") at 12 to 18 months was among the most predictive early markers identified in that age window ^[4]. No pointing doesn't equal autism. It does mean take it seriously and get eyes on your child sooner.

Seeing more than one of these together? Don't wait for the next well-child visit. Call your pediatrician this week. In most states you can also self-refer to early intervention without going through a doctor first.

How does 15-month speech connect to 20-month milestones?

Plenty of parents find an article like this around 15 months, read the "watch and wait" line, and don't come back until their kid is 20 months and they're genuinely alarmed. Knowing the trajectory now saves you that gap.

By 20 months, the AAP and ASHA both expect a child to say at least 50 words and start combining two words, things like "more milk" or "daddy go" ^[1][3]. The jump from 1 to 10 words at 15 months to 50 at 20 months sounds steep, and it is. The vocabulary explosion usually lands between 18 and 20 months, and in kids who are on track it happens fast.

A speech delay in a 20-month-old is often the same quiet issue that was already there at 15 months. The child who said two words at 15 months and was told to wait often shows up at 20 months still saying 5 to 10 words, now carrying a five-month gap that didn't need to happen. That's not a knock on any one pediatrician. It's a known limit of surveillance-only care. It's exactly why ASHA says any child with fewer than 10 words at 18 months should be referred for a speech-language evaluation instead of monitored longer ^[3].

By 20 months, a child with a speech delay also starts to show frustration during communication, because they understand far more than they can say. That frustration sometimes reads as behavior problems. Close the communication gap and the behavior usually eases too.

What's the difference between a late talker and a speech delay?

Parent groups use these terms interchangeably. Clinicians don't.

A "late talker" usually means a child between 18 and 30 months with fewer words than expected but otherwise typical development across thinking, social skills, hearing, and motor skills. Comprehension is in range. They understand you, they just don't say much. Roughly 70 to 80 percent of late talkers catch up on their own by age 3, the group researchers call "late bloomers" ^[5]. The other 20 to 30 percent go on to have lasting language delays.

A "speech delay" is the broader clinical term. It includes late talkers, plus children who have an underlying reason for the delay: hearing loss, childhood apraxia of speech, language processing differences, autism, or delays across several areas.

Here's the practical problem. You cannot tell from the outside, at 15 months, which group your child is in. That's the exact thing a speech-language pathologist (SLP) evaluates. So the move isn't to guess the bucket and decide whether to act based on the guess. The move is to get an evaluation so someone qualified can tell you.

Hearing gets ruled out first, every time. A child who can't hear well can't develop speech normally. Audiologists test hearing reliably even in infants, and a hearing test is the first step in any speech evaluation worth its time.

What does a 15-month speech evaluation actually look like?

Parents sometimes skip an evaluation because they picture something clinical and stressful for their toddler. It's far more low-key than that. Mostly it's an SLP playing with your child.

A speech-language evaluation at this age runs 45 to 60 minutes of the SLP playing with your child while taking structured notes, plus a long interview with you about your child's history. The SLP watches how your child communicates (more than whether they talk), how they play, whether they point and gesture, how they respond to language, and whether speech sounds are coming along. You'll usually fill out a standardized questionnaire too. Some evaluations include a hearing screen; others send you to audiology separately.

For children under 3 in the United States, this evaluation is free through the Individuals with Disabilities Education Act (IDEA) Part C program, which covers early intervention. You don't need a diagnosis. You need only a concern and a phone call ^[6]. Services happen in your home or a community setting, and families cannot be turned away over ability to pay.

If your child is 3 or older, the evaluation moves to IDEA Part B through your local school district, also at no cost. Private SLPs evaluate at this age too. Prices vary a lot, commonly $150 to $350 for an evaluation depending on your area and your insurance. Online speech therapy has made access much easier for families in rural areas or places with few local providers.

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

The evidence on parent-run strategies is genuinely good. Responsive interaction, where you follow your child's attention and narrate what they're looking at and doing, shows consistent positive effects on early language ^[7].

What that looks like in real life: your child picks up a block. Instead of asking "what color is that?" (a test, which produces no language model), you say "block. You have the block. Blue block." Simple, flat, no pressure. Then you stop. The pause is the part most parents skip. They fill the silence too fast and never give the toddler room to answer.

A few strategies with research behind them at this age:

Self-talk and parallel talk. Narrate what you're doing and what your child is doing, in simple words. "Mommy is pouring water. You're splashing."

Expansions. Your child says "ball." You say "big ball" or "throw ball." You're not correcting. You're modeling the next step.

Wait time. Give 5 to 10 seconds after a question or a pause before you jump in. It's genuinely hard and genuinely works.

Read aloud daily. Not for comprehension, for exposure. Board books where you point and name, or books with simple repeated phrases, do the most at this age.

What to skip: flashcard drills, making your child "say the word" before you hand over what they're asking for, and TV running in the background as ambient noise. Background television has a documented negative link to early language outcomes ^[8].

If you want structured daily practice, the Little Words app was built to guide parents of late talkers and neurodivergent kids through these activities, with a quiz that finds your child's communication profile and suggests targeted next steps.

Could my 15 month old's speech delay be related to autism?

It could be, and it's worth knowing what to look for. About 40 percent of autistic people are minimally verbal or nonspeaking, and many autistic children show their first clear differences in the 12 to 18 month window ^[4]. But a speech delay at 15 months is also very common in children who are not autistic. Most late talkers aren't.

The features that lean more toward autism (again, not a diagnosis, just "talk to your doctor now"):

• Speech delay plus reduced eye contact or not responding to their name
• Speech delay plus no pointing or showing objects to share interest
• Repetitive movements (hand flapping, rocking, spinning objects) alongside the language delay
• Loss of words they used to say
• Very rigid play (lines up toys only, doesn't copy your actions)

Speech delay without those features makes autism less likely, though not impossible. Several of those features together with the speech delay is your cue to request a developmental pediatrician referral or a full developmental evaluation. The AAP recommends autism-specific screening at the 18-month and 24-month well-child visits using a validated tool like the M-CHAT-R/F ^[1].

For families dealing with both a speech delay and possible autism, autism spectrum speech therapy works a bit differently from general speech therapy, with more weight on functional communication and other modalities. AAC devices are sometimes introduced early here, and the research is clear that early AAC does not suppress speech. It tends to help it ^[9].

What about early intervention? How do I actually get it?

Under IDEA Part C, every state runs a program that gives free evaluation and services to children under 3 with developmental delays or conditions that put them at risk ^[6]. Services cover speech-language therapy, occupational therapy, physical therapy, and parent coaching, delivered in your home or childcare setting.

To start, you call your state's early intervention program. No doctor's referral needed, though your pediatrician can refer too. After you call, the program has 45 days to finish an evaluation. If your child qualifies, you build an Individualized Family Service Plan (IFSP) together and services begin.

The honest catch: wait times swing hard by state and county. Some families wait weeks, some wait months. It's a real system problem with no clean fix. Your best lever is to call as early as you can and follow up like a dog with a bone. Calling at 15 months when you have concerns, instead of waiting until 18 or 20 months, is not overreacting. It's smart.

The timing evidence is clear: services started before age 3 produce larger, faster gains than the same services started later ^[10]. Early intervention is not a last resort. It's the first tool.

After age 3, services shift to the school district under IDEA Part B. The steps rhyme: request an evaluation in writing, the district has 60 days to evaluate, and if your child qualifies, you build an Individualized Education Program (IEP).

Is there anything causing speech delays I might not have considered?

Hearing loss is the one nobody wants to miss. Even a mild, fluctuating loss from chronic ear infections (otitis media with effusion) can hold back early language, because the child is getting muffled or on-again-off-again input during the most important window ^[11]. If your child has had repeated ear infections or tubes, make sure a current audiological evaluation is part of the workup.

Oral motor differences are another factor that flies under the radar. Some toddlers have low muscle tone in the jaw, lips, or tongue (sometimes called hypotonia) that makes speech sounds harder to produce, even when understanding is fine. An SLP trained in feeding and oral motor development can assess it.

Childhood apraxia of speech (CAS) is less common but does show up in this age range. It's a motor speech disorder where the brain struggles to plan and sequence the movements for speech. Childhood apraxia of speech tends to show inconsistent errors, few consonant sounds, and a lot of effort for little output. It responds well to specific, frequent therapy and does not resolve on its own.

Some genetic conditions (Down syndrome, fragile X, 22q11.2 deletion) predictably affect speech. If your child has a known genetic diagnosis, a speech therapy referral now, without waiting, is the right call.

One myth to bury: bilingual and multilingual homes do not cause speech delays. Research consistently shows simultaneous bilingual acquisition tracks similarly to monolingual acquisition once you count words across both languages ^[7]. If your child is growing up with two languages, the number that matters is total words across both.

A side-by-side look at 15-month and 20-month speech expectations

Parents often want a clean comparison across these two ages. Here's what the milestones look like, drawn from AAP surveillance guidelines and ASHA resources ^[1][3].

The gap between expressive word count and comprehension carries a lot of weight. Children typically understand two to four times as many words as they say. A 15-month-old who says nothing but clearly understands 40 words and points well is in a different category than one who does none of that. Both deserve evaluation. The clinical picture just isn't the same.

A speech delay in a 20-month-old who hasn't been evaluated yet isn't a crisis, but it is overdue. The window for the easiest, most effective early intervention is closing. Book the evaluation.

When should I push back on 'wait and see'?

"Wait and see" is sometimes the right call and sometimes not, and parents deserve to know which is which.

Watching and waiting can be reasonable if your child has 3 to 10 words at 15 months, solid comprehension, good pointing, steady eye contact, and no other developmental concerns. A re-check at 18 months with a clear plan makes sense there.

Push back if your child has zero words at 15 months, has lost words they used to say, doesn't respond to their name, doesn't point, or shows any of the autism-associated features above. The research does not support watchful waiting in those cases ^[1][3].

Push back too if your gut says something is wrong and the clinician waves it off fast. You know your child better than anyone. "First child, first-time parent worrying" is real, but so is a genuine early delay getting minimized. Asking for an early intervention referral costs nothing and closes no doors. You can always decline services after the evaluation if everything checks out.

A good pediatrician won't take offense at a parent asking for a speech evaluation. If yours does, that's information too.

For families wanting structured support between now and the appointment, speech therapy guidance is increasingly available in digital formats that can supplement, not replace, a professional evaluation.

Frequently asked questions

How many words should a 15 month old say?

Most 15-month-olds say between 1 and 10 words, with the 50th percentile around 10 words per MacArthur-Bates CDI data. The AAP flags zero words as a reason to refer for evaluation right away. Comprehension (understanding around 50 words) and pointing matter as much as word count at this age, so weigh the whole picture, more than the count.

What if my 15 month old says no words at all?

Zero words at 15 months is a clear red flag under AAP and ASHA guidelines. Call your pediatrician this week and ask for an early intervention referral, or contact your state's early intervention program directly. You don't need a doctor's referral to get a free evaluation under IDEA Part C. Don't wait for the next well-child visit.

Is 'mama' and 'dada' enough at 15 months?

It depends on how they're used. If your child says "mama" specifically for you and "dada" for their other parent, those count as two words. If they say both indiscriminately for everything, they don't count as true words. At 15 months, clinicians want at least one clear word used consistently for a specific thing.

What's a normal speech milestone for a 20 month old?

At 20 months, the AAP and ASHA expect at least 50 words and the start of two-word combinations like "more juice" or "daddy shoe." A speech delay in a 20-month-old means fewer than 50 words or no combinations emerging. That threshold is the standard referral trigger, and evaluation should happen promptly, not at 24 months.

Does watching TV or screens cause speech delay?

Background TV in particular has a documented negative link to early language, likely because it interrupts the back-and-forth that builds language. The AAP recommends avoiding screen media other than video chatting for children under 18 months. For 18 to 24 months, if screens are used, co-viewing with a parent and talking about what's on screen lowers the risk.

Can bilingual children have speech delays?

Growing up bilingual does not cause speech delay. Research shows bilingual children acquire language on a similar timeline once you count words across both languages. A bilingual 15-month-old who says two words in English and three in Spanish has five words total, well within range. Always tell your evaluator about both languages so they can assess accurately.

What causes speech delays in toddlers?

Common causes include hearing loss (rule this out first), family history of late talking, ear infections affecting hearing during development, oral motor differences, childhood apraxia of speech, autism, and general developmental delays. In many late talkers, no specific cause turns up. A speech-language evaluation plus a hearing test identifies the factors that apply to your child.

How is early intervention different from private speech therapy?

Early intervention (IDEA Part C) is free for children under 3, happens in natural settings like your home or daycare, and leans heavily on coaching parents to support speech all day. Private speech therapy is paid or insurance-covered, usually happens in a clinic, and is directed by the SLP. Both can work, and many families use both. Early intervention is the right first call for most families under 3.

Could pointing without words be okay at 15 months?

A child who points clearly but says few words is showing strong communication intent, which is a good sign. Pointing is one of the strongest predictors of later language. Still, if your child is 15 months, points well, but has zero actual words, it's worth a call to early intervention or your pediatrician. Pointing plus zero words is watchful-waiting territory, not panic territory.

What is echolalia and does it mean my toddler has a problem?

Echolalia is repeating words or phrases heard from others, like scripts from TV shows or things a parent just said. Some echolalia is completely normal in toddlers 15 to 30 months; it's one way children practice language. When echolalia is the only form of communication (no spontaneous words or requests), or when it persists past age 3 as the main speech pattern, it warrants evaluation. See our deeper overview of echolalia.

What is the M-CHAT and when should it be done?

The M-CHAT-R/F (Modified Checklist for Autism in Toddlers, Revised with Follow-Up) is a validated autism screening tool the AAP recommends at the 18-month and 24-month well-child visits. It takes about 5 minutes and parents complete it. It asks about pointing, eye contact, imitation, and social communication. A positive screen leads to a follow-up interview and possibly a full developmental evaluation, not a diagnosis.

Should I be worried about speech delay if my child understands everything?

Good comprehension with limited expressive speech is a classic late talker profile, and many of these children do catch up. But "most" is not "all." About 20 to 30 percent of children who understand well but say little at 18 to 20 months go on to have persistent language delays. An evaluation at 15 to 18 months is still the right call, because there's no downside to getting one.

What does a speech therapist actually do with a 15 month old?

Mostly play. A skilled pediatric SLP uses toys, books, and games to watch how your child communicates, imitates, requests, and responds to language. They note what sounds your child makes, whether they pair gestures with sounds, and how they interact with you. The SLP also coaches you directly, because at this age parent-run strategies during daily routines drive the most progress.

My 20 month old has a speech delay. Is it too late for early intervention to help?

No. Twenty months sits well inside the highest-impact window for early intervention. Services under IDEA Part C run until age 3, and the outcome research for children who start between 18 and 30 months is strong. Call your state's early intervention program today. The only way it becomes too late for the biggest gains is if you wait past age 3.
