Bilingual toddler not talking: what's normal and what to do

Last updated 2026-07-09

Is it normal for a bilingual toddler to talk later?

No. Bilingual children reach language milestones at the same ages as monolingual children. This is probably the most stubborn myth in early childhood development, and it does real harm, because it hands worried families a reason to wait.

The American Speech-Language-Hearing Association is direct on this point ^[1]. Bilingual kids may mix two languages in a single sentence, called code-switching, and that's completely typical. What matters is that the total number of words they know across both languages keeps pace with their peers. A 24-month-old who knows 30 words in English and 25 in Spanish has a combined vocabulary of 55 words, well past the 50-word mark.

The myth grew out of a real finding that got misread. Bilingual kids sometimes have slightly smaller vocabularies in each single language than a monolingual child the same age, simply because their input is split between two. Count total conceptual vocabulary, though, and the gap disappears ^[2]. The catch is that many screening tools test only one language, which makes bilingual kids look behind when they're actually on track.

So when a pediatrician or a well-meaning relative says "oh, he's just confused by two languages, give it time," that advice has no support in current research. Confusion doesn't cause delay. What causes delay is a genuine language or developmental issue that happens to sit alongside bilingualism.

What are the real speech milestones for bilingual toddlers?

Count words across both languages together, then compare against the table below. The American Academy of Pediatrics developmental surveillance guidance ^[3] and ASHA's norms ^[1] line up closely here, and both count combined vocabulary for bilingual kids.

Those numbers come from large normative samples, and nobody expects a child to hit the exact figure on the exact day. But if your child is more than a month or two behind on several rows of that table, treat that as your signal to act.

One red flag gets nowhere near enough attention: a bilingual toddler who had words and then stopped using them. Loss of language, in any language, is never a wait-and-see situation. The AAP recommends immediate evaluation if a child loses skills at any age ^[3].

Another flag slips past parents all the time: a child who communicates heavily through gestures, pointing, or pulling your hand toward things, but produces very few actual words. Gestures are good, and a real precursor to talking. But if gestures are doing all the work by 18 months and words stay sparse in both languages, that pattern deserves a look.

Late talker or language disorder: how do you tell?

Honestly, you often can't tell from the outside, not without a proper evaluation. That's the question that haunts parents at 2 a.m., and the plain answer reflects real clinical reality rather than a dodge.

A "late talker" in the research literature is a child aged 18 to 30 months who has fewer words than expected, but whose comprehension, social engagement, play skills, and hearing all check out fine. Somewhere between 50 and 70% of late talkers catch up by school age without any intervention ^[4]. These are the kids people call "late bloomers."

Here's the trap in that statistic: you cannot reliably tell at age 2 which children will bloom and which won't. The ones who don't catch up carry higher risk for reading difficulties, social communication challenges, and lasting language disorders ^[4]. Guessing wrong has a real cost. Early intervention services in the U.S., available through the IDEA Part C program for children under 3, are free and require no diagnosis to start ^[5].

Language disorders tend to look different from plain late talking. A child with a language disorder usually struggles more with understanding language than with producing it. Watch for trouble following two-step directions ("get your shoes and put them by the door"), not responding to their name reliably, thin eye contact or joint attention (pointing at things to share interest, not only to request), and very restricted play, like lining objects up instead of pretending with them.

If any of those social communication signs show up alongside the speech delay, the picture is more complex and evaluation becomes urgent rather than optional. None of this amounts to a diagnosis on its own. It's a flag that the delay may not be purely about getting words out.

Does speaking two languages cause or worsen a delay?

No. Bilingualism doesn't cause speech or language disorders, and it doesn't make an existing one worse ^[2]. A child with a language processing difficulty will have it whether one language is spoken at home or two.

A 2010 review by Kathryn Kohnert in the American Journal of Speech-Language Pathology, drawing on the broader bilingual disorders literature, found the disorder rate is roughly the same in bilingual and monolingual children, around 7 to 8% of the population ^[2][10]. Two languages don't add risk.

There's also no evidence that dropping a home language and switching entirely to the majority language helps a delayed child catch up faster. It can do the opposite: it cuts the child off from the richer, warmer input of caregivers who speak the home language fluently and naturally, which is exactly what a language-delayed child needs more of. ASHA states plainly that parents should keep using the language they speak most comfortably ^[1].

This is one of those cases where the "obvious" fix, just speak one language so the kid isn't confused, is flat wrong. Rich, consistent input in whatever language a caregiver speaks best beats a thin diet of the majority language from someone who isn't fluent in it.

What language should you speak to a bilingual toddler who has a speech delay?

Speak the language you speak best. That's the whole answer, and the evidence backs it up.

The reason matters. Input quality rides on vocabulary richness, natural rhythm and prosody, how quickly you respond to your child's attempts, and the warmth that comes with speaking your strongest language. Force a Spanish-dominant parent to run every conversation in English and you get flatter affect, simpler words, and fewer spontaneous replies to the child's cues. Those things matter enormously for a child already working hard to build language.

When parents speak different languages, the "one parent, one language" approach (OPOL) is a reasonable structure. But the research on whether it beats mixed-language input is genuinely thin. Consistency, volume, and responsiveness matter far more than the specific strategy label you pick.

Volume deserves its own line. Children learn language by hearing a lot of it, in real conversation, in books, in narrated daily routines. A delayed child needs more input, not less. Talking through what you're doing ("I'm putting the apple in the bowl, now I'm cutting it, look, two pieces") is the kind of naturalistic input speech therapists call self-talk and parallel talk, and it costs nothing.

If you're working with a speech therapist, ask them directly whether sessions should focus on one language or both. For a bilingual child the answer should generally involve both, ideally with a therapist who is bilingual or who works alongside a bilingual assistant.

How do you get a bilingual toddler evaluated for a speech delay?

Two routes exist, and you can run both at once. Start today. Neither one requires waiting for the next scheduled appointment.

The first is your child's pediatrician. At the 18-month and 24-month well-child visits, the AAP recommends standardized developmental screening ^[3], often using the M-CHAT-R (Modified Checklist for Autism in Toddlers, Revised). If screening flags a concern, the pediatrician refers you to a speech-language pathologist (SLP) or a developmental pediatrician, but you don't have to wait for that visit to roll around. Call and ask for a referral if you're worried now.

The second is your state's Early Intervention program. Under the Individuals with Disabilities Education Act Part C, every state has to provide free evaluations and services to children under 36 months with developmental delays or conditions likely to cause them ^[5]. You can self-refer, no doctor's order needed. Find your state's program through the CDC's Learn the Signs. Act Early. pages ^[7], or call 1-800-CDC-INFO.

For a bilingual child, insist on an evaluation that covers both languages. A monolingual English assessment often underestimates what a bilingual child can actually do, which cuts both ways: it can label a typical bilingual child as delayed, or miss a real disorder the child masks in one language. Ask directly whether the evaluating SLP has experience with bilingual assessment, and if not, ask for someone who does.

If cost or access is what's holding you back, know that early intervention under IDEA Part C is free for families who qualify on developmental grounds, not income. Congress built the program this way because catching things early changes outcomes. For a broader look at what the therapy itself involves once you're in, the speech therapy speech therapist overview is a solid starting point.

Why does this feel so frustrating?

Because it genuinely is hard, and that frustration doesn't make you a bad parent.

Not being able to communicate with your own child wears you down in a way that's hard to explain to anyone who hasn't lived it. You don't know if they hurt, what they want, whether they even understood you. Every meal, every car ride, every bedtime turns into a guessing game, and that's stacked on top of fear for their future, comments from relatives, and a medical system that keeps telling you to wait.

Some of the frustration is physiological. Chronic communication failure is stressful, and your nervous system reacts to it. That's not a character flaw.

A few things help in practice. Set up a simple, consistent signal for urgent daily needs, things like eat, drink, more, stop. This isn't giving up on words; it cuts the daily friction while language builds underneath. AAC devices and low-tech picture boards do this job well. When you're in the thick of it and need to reset, drop the pressure to communicate for a few minutes: get on the floor, follow your child's lead, play with whatever they're into without pushing for speech. Therapists call this floor time or child-directed interaction, and it tends to produce more spontaneous language than drilling ever does.

Your own mental health matters here too. Parent stress shapes how responsive you can be, and responsiveness is one of the strongest predictors of language development. Finding support, whether that's a parent group, a therapist, or an online community of families in the same spot, isn't a luxury.

What can parents do at home to help a bilingual toddler talk more?

Respond, expand, read, and comment more than you question. These strategies come from parent-implemented intervention research and match what ASHA recommends for families working alongside professional services ^[1]. They don't replace an evaluation, but they run alongside one and produce real gains.

Respond to every communication attempt. If your child points at the cup, say the word in your language, hand it over, and say it again: you're pairing meaning with sound. Treat any vocalization as a real communicative act, because it is one.

Expand on what your child says. They say "ball," you say "red ball" or "big ball roll." This is called expansion, one of the best-studied home strategies in the language literature ^[4], and it models the next step without correcting or demanding imitation.

Read books every day, in any language. Point at pictures, name them, then pause and wait. The pause matters, since it opens space for your child to try a word or gesture. If nothing comes after three to five seconds, just model the word yourself and move on rather than quizzing them.

Cut questions and add comments instead. "What's that?" is a demand. "Oh, a doggy, the doggy is running" is a model. Toddlers actually produce more language in response to comments than to questions, which feels backwards until you try it.

Little Words is built around this kind of parent-coached daily practice, and the start quiz can help you figure out where your child stands and what to work on first, bilingual context included. If you're also seeing repetitive or echoed speech, the echolalia article explains when that's a normal stage and when it's worth a closer look.

Could my bilingual toddler's speech delay be related to autism?

It could be, and the overlap is worth understanding without jumping to conclusions.

Autism spectrum disorder (ASD) involves differences in social communication, which includes speech but goes well beyond it. The line between a plain language delay and ASD-related communication differences usually sits in the social domain: joint attention (pointing to share interest, following a gaze), back-and-forth play, and nonverbal communication like gesture and facial expression.

A bilingual child can have ASD. Being bilingual doesn't protect against it and doesn't cause it either; ASD shows up across all language communities at roughly similar rates. If your child shows reduced eye contact, very limited pointing or gesturing, little interest in other children, or rigid repetitive behaviors alongside the speech delay, those signs point toward an evaluation for ASD specifically, rather than a general speech check.

For parents at that intersection, autism spectrum speech therapy covers what evidence-based therapy looks like for children with ASD, including AAC options and social communication approaches. The guidance for bilingual children with ASD holds steady either way: keep using the home language, seek bilingual services where you can, and don't let worry about bilingualism delay the evaluation or the start of services. Research doesn't support the idea that dropping one language improves outcomes for children with ASD.

What if my child has apraxia of speech and is also bilingual?

Childhood apraxia of speech (CAS) is a motor speech disorder where the brain struggles to program the movements speech requires. It's relatively rare, affecting roughly 1 in 1,000 children, but it's one of the more common reasons a child produces very few intelligible words despite clear comprehension and social engagement ^[6].

In bilingual children, CAS can look like near-silence in one language, or inconsistent production where a word is crisp one day and gone the next. Because it's a motor disorder, it hits the production mechanics no matter which language is being spoken: both get affected.

CAS calls for specific therapy, particularly DTTC (Dynamic Temporal and Tactile Cueing) and the Nuffield Dyspraxia Programme, rather than general language stimulation ^[6]. That's worth knowing, because a well-meaning "just talk more" approach won't move the needle for a child with CAS.

Bring up CAS by name with the evaluating SLP if your child's speech errors are highly variable ("baba" for bottle one day, "bata" the next), if they struggle to imitate sounds even when they clearly want to, and if longer words trip them up more than short ones. The childhood apraxia of speech article has more on diagnosis and treatment. For bilingual families, the approach stays the same: CAS treatment should involve both languages, ideally with a therapist who has bilingual capability or can consult with one.

Questions parents ask most often

Do bilingual toddlers talk later than monolingual toddlers?

No. ASHA's guidance is clear that bilingual children hit language milestones at the same ages as monolingual children, as long as vocabulary is counted across both languages together. The myth sticks around because single-language tests can make bilingual kids look behind when they're not. A child with 50 words total across both languages by 24 months is on track.

How many words should a bilingual 2-year-old have?

Around 50 words total, counted across both languages, is the benchmark at 24 months, drawn from normative data used by ASHA and the AAP. By 30 months, most children have 200 or more words and are combining them into short phrases. If your 2-year-old is well under 50 total words, ask for a speech evaluation.

Should I stop speaking my home language so my toddler learns English faster?

No. ASHA advises parents to speak whichever language they know best, because rich input from a fluent speaker helps language development more than simplified input in a second language does. There's no evidence that dropping the home language speeds up the majority language. Speak your strongest language, and get a professional evaluation if you're worried.

Can being bilingual make autism harder to diagnose?

It can, if a clinician mistakes code-switching or uneven language distribution for social communication deficits. That's why a bilingual evaluation from an experienced clinician matters so much. The core signs of ASD (reduced joint attention, limited reciprocal play, restricted gestures) show up across languages, and a proper bilingual autism evaluation should be conducted in both languages whenever possible.

What is code-switching, and is it a sign of delay?

Code-switching is when a bilingual child mixes words from both languages in one sentence, like "I want more leche." It's developmentally normal and actually reflects sophisticated language knowledge rather than confusion. It is not a sign of delay. Bilingual children, and bilingual adults for that matter, code-switch because it's often the most natural or precise choice in the moment.

My toddler understands both languages but doesn't speak much. Is that a delay?

Strong comprehension paired with limited production is a fairly common pattern, and some children are just late talkers who catch up. But "my child understands everything" is sometimes a parent's impression rather than something formally tested. An SLP evaluation checks comprehension directly. If comprehension turns out to be solid and production is the only real gap, that's a more hopeful picture, though it still deserves monitoring and often some intervention.

How do I find a bilingual speech-language pathologist?

ASHA runs a provider locator at asha.org that lets you filter by language, and state Early Intervention programs keep their own lists of bilingual providers. Ask specifically whether the SLP assesses and treats in your child's exact language, not just whether they're bilingual in general. For less common languages, ASHA guidance accepts a trained interpreter working alongside a monolingual SLP as an alternative.

Does my bilingual toddler need speech therapy in both languages?

Generally, yes, especially for the assessment. Therapy itself can run mostly in one language if the goal is community functioning, but research suggests skills generalize better when both languages are part of treatment. At the very least, the initial evaluation should cover both. Ask your SLP directly how they approach bilingual treatment: one who works only in the majority language may miss real strengths and real gaps.

What is early intervention, and how do I access it?

Early Intervention is the federally mandated program under IDEA Part C, offering free developmental evaluations and services to children under 36 months. You can self-refer by contacting your state's program directly, no doctor's order needed. If your child qualifies, they get an Individualized Family Service Plan (IFSP), and services can include speech therapy, occupational therapy, and developmental support in your home.

Is it normal for a bilingual toddler to go through a silent period?

A brief silent period, when a young child is suddenly immersed in a second language (starting daycare, say), is a well-documented part of second language acquisition. It usually runs weeks to a few months, not a year or longer. A child who's never been verbal in either language isn't experiencing a silent period, that's something else. If silence stretches past a few months, or your child is over 18 months with no words at all, get an evaluation.

Can screen time cause a bilingual toddler to talk less?

Heavy passive screen time is linked to less parent-child verbal interaction, and that's really the mechanism to worry about. The AAP recommends no screen time under 18 months except video chat, and limited high-quality content between 18 and 24 months with a caregiver watching alongside the child. Screens themselves aren't the problem so much as what they displace: the responsive, back-and-forth interaction that drives language learning.

At what age is it too late for speech therapy to help?

It's never too late for speech therapy to make a difference, but earlier is meaningfully better. Language plasticity peaks before age 5, and the research on early intervention consistently shows better long-term outcomes when services start before age 3 rather than later. If your child is already past 3, start now instead of waiting further. The gap between acting today and acting six months from now still counts.

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

A speech delay is about pronunciation and articulation: the child is attempting words, but the sounds come out unclear or off for their age. A language delay is broader, covering vocabulary size, sentence structure, and comprehension. Bilingual children can have either one, both, or neither. An SLP evaluation tells them apart, which matters because the treatments differ. Don't assume unclear speech is just an accent or a bilingual quirk without getting a professional opinion first.
