Michael is three years and two months old. He brings his slippers when his dad says they are going for a walk, hands his grandmother her glasses before she has a chance to ask, and laughs at his older sister’s jokes. He says a dozen or so words, some of which only his mother understands. When he wants something, he pulls an adult by the hand or points. At the last visit the paediatrician said that “boys talk later”; his grandmother says his dad also started talking late. His parents have been hearing this for a year and believe it less and less.
“He doesn’t talk, but he understands everything” is one of the sentences speech-language therapists hear most often. This article explains what it means in a three-year-old, what research says about late-talking children, what the causes may be and what to do right now. It does not replace a consultation — it helps you prepare for one.
Is it normal for a 3-year-old not to talk but understand everything?
It is not something worth simply waiting out in a three-year-old. According to the CDC milestones list, most children aged three hold a conversation with an adult over at least two exchanges, ask “who”, “what”, “where” and “why” questions, and speak clearly enough that others usually understand them. A three-year-old who says single words or nothing at all needs a speech-language assessment and a hearing test now, not in six months.
Good understanding of speech is, however, genuinely important information, and good news. The American Speech-Language-Hearing Association (ASHA) points out that children whose delay affects only expressive language have a better outlook than children who also have difficulty understanding. Understanding is therefore not a reason to wait, but a reason to act more calmly.
What a three-year-old says — a point of reference
The CDC list describes what about three quarters of children do at a given age, so it is not a minimum but a point of reference. Even so, with speech the gap between a typical three-year-old and a child saying single words is large enough that it is worth seeing in one place.
| What most three-year-olds do (CDC) | What to observe in your child |
|---|---|
| Talks with an adult in at least two back-and-forth exchanges | Whether they answer with a word, a gesture or only with action |
| Asks “who, what, where, why” questions | Whether they ask at all, even with a gesture or intonation |
| Says what is happening in a picture, e.g. “running”, “eating” | Whether they point to what you ask about in a picture |
| Says their first name when asked | Whether they respond to their name, turn round, look |
| Talks well enough for others to understand most of the time | How many words people outside the home understand |
| Notices other children and joins them to play | Whether they are interested in children, copy them, play pretend |
The right-hand column is not a test, just a prompt for what to note down before seeing a specialist. Concrete observations from everyday life tell a therapist more than a general “doesn’t talk much”. What a three-year-old does in other areas of development is described in the article on what a 3-year-old should be able to do.
How to check whether your child really understands everything
Parents often judge understanding by how a child copes in everyday situations. This is an important clue, but it can be misleading. A three-year-old who brings slippers on hearing “we’re going for a walk” may understand the words, or may understand the situation: Dad got up, picked up the keys, it is time to go out. Children are masters at reading context.
A simple home check: ask your child for something unusual, without gestures and without looking at the object. “Put the spoon on the chair”, “give teddy his shoes”, “bring a towel from the bathroom”. If a three-year-old follows such instructions, including two-part ones, their understanding is probably good. If they manage only routine requests in familiar situations, or only when an adult points, it is worth noting and telling the therapist.
The second thing to observe is how the child communicates without words. Do they point to show you something interesting, not just to get it? Do they look at the adult’s face to check whether they can see it too? Do they nod, wave, bring things to show them? These gestures say a lot about how the child understands what a conversation is — and according to research cited by ASHA, they help predict whether a child will catch up with their peers.
Late-talking children — what research says
In the speech-language literature, children who start talking later than their peers but otherwise develop typically are called late talkers. ASHA describes this as late language emergence and gives a commonly used criterion: fewer than 50 words and no two-word combinations at 24 months.
The key figures from the ASHA review:
- Prevalence. Depending on the study, late language emergence affects 10–20% of two-year-olds.
- Sex and family. Boys are affected about three times as often as girls, and children with a family history of late talking more often than others.
- Outlook. About 50–70% of late-talking children catch up with their peers by late preschool or school age.
- What helps predict catching up. Children who caught up more often used gestures and less often had difficulty understanding speech.
- What remains. Even children who catch up score on average slightly lower on language tests than children with no history of delay, and late talkers have a higher risk of later difficulties with language and reading.
Two conclusions follow from these figures, and it is worth holding both at once. First: many children who start talking late catch up, and good understanding and gestures are good signs. Second: at the outset it is impossible to say which child will catch up and which will not — that is known only after the fact. That is why ASHA recommends checking a child’s speech regularly, roughly every six months, rather than waiting without monitoring.
A three-year-old is already past the age at which people usually speak of a “late-talking” two-year-old. Norms and warning signs from the earlier stage are described in the article on toddler speech development.
Why isn’t a three-year-old talking?
There may be several causes, and they often cannot be told apart without a specialist. Those most often considered are late language emergence with no other difficulties, hearing loss, developmental language disorder, difficulty planning the movements needed for speech, autism spectrum disorder and global developmental delay. In every case the first step is a hearing test, because even partial hearing loss can hold back speech development and is easy to miss.
Briefly on each possibility:
- Late language emergence. The child understands, plays and makes contact, but talks later than peers. This group has the best outlook but still needs monitoring.
- Hearing loss. A child may hear loud sounds and respond to their name, yet not hear some speech sounds clearly. ASHA lists a hearing test as a standard part of assessing a late-talking child, and the therapist’s case history also asks about past middle ear infections.
- Developmental language disorder. The difficulty lies in language itself: building sentences, word endings, understanding complex statements. It is identified by a speech-language therapist, usually after observation over a longer period.
- Difficulty planning speech movements. The child knows what they want to say but struggles to plan the movements of the lips and tongue. A speech-language therapist assesses this.
- Autism spectrum disorder. Speech delay can be one of the first signs, but autism concerns above all social communication and is not diagnosed from speech alone.
- Global developmental delay. Speech is then one of several areas in which the child develops more slowly.
The list is not for self-diagnosis. It shows why a therapist may ask for a hearing test or a consultation with another specialist — not because they suspect the worst, but because they want to rule out further possibilities.
3-year-old not talking — is it autism?
Speech delay alone does not mean autism. Many three-year-olds who say little otherwise develop typically: they make eye contact, show things in order to share them, take an interest in other children and play pretend. In children on the autism spectrum, the difficulty concerns above all social communication — how the child makes contact and shares attention with another person — rather than the number of words.
The CDC lists examples of behaviours worth discussing with a doctor because they may be linked to autism. Among them are: avoiding eye contact, not responding to their name, not pointing to show something interesting, not noticing other children and not joining their play by age three, and repetitive behaviours: lining up toys and getting very upset when the order is changed, repeating the same words or phrases, focusing on parts of objects such as wheels, flapping hands, and strong reactions to sounds, smells or textures.
At the same time the CDC stresses that some children without autism also show some of these traits. A single behaviour decides nothing. A diagnosis is made by a team of specialists, not by a list from the internet. But if a parent sees several of these signs at once in a three-year-old, it is not worth waiting — an early diagnosis gives access to support when it helps most.
Who to see and in what order?
The simplest route starts with the paediatrician, who knows the child and can refer onwards, and a speech-language therapist, who will assess speech and understanding. In parallel it is worth having the child’s hearing tested, because without that no speech assessment is complete. Depending on what the therapist sees, the next step may be a consultation at a psychological and educational counselling centre or with a medical specialist, such as a paediatric neurologist or child psychiatrist.
An order that usually works:
- Paediatrician. Describe your observations and ask about a developmental assessment and referrals. If a routine check-up is coming up, it is a good opportunity, but there is no need to wait for it.
- Hearing test. With an ENT specialist or at an audiology clinic, even if the child “definitely hears”.
- Speech-language therapist. They will assess expressive language, understanding, gestures, play and pronunciation, suggest a plan and a date for reassessment.
- Psychological and educational counselling centre. In Poland, public counselling centres help children from birth: they assess, issue opinions and statements of need, and support parents. This is where an opinion on the need for early development support is issued; such support covers children with a disability from the time it is identified until they start school.
- Further specialists. If the therapist or counselling centre need them — a neurologist, a child psychiatrist, an autism assessment team.
Before the visit, write down concrete observations: how many words the child says and which ones, how they communicate their needs, whether they point, how they respond to their name, whether they play pretend, whether they could once do something and have stopped. According to the CDC, losing skills the child once had is a signal to talk to a doctor without delay.
What to do at home while you wait
The wait for a first specialist appointment is sometimes weeks, and that time need not be wasted. ASHA describes ways of talking with a child that support language development and that a parent can use straight away:
- Respond to every attempt to communicate. A gesture, a sound, a look is also a message. When the child points at a cup, say “Cup. Do you want a drink?” and hand it over.
- Speak briefly and concretely. Name what the child is looking at and doing: “You’re putting in a block. A big block.”
- Imitate and expand. If the child says “car”, say “red car” or “car’s going”.
- Use gestures together with words. A gesture does not replace a word; it supports it. How this works in practice is described in the Polish-language article on Makaton.
- Wait. After a question or a sentence you have started, wait a few seconds. A child who says little needs more time to answer, and adults usually answer for them.
- Praise the attempt, not the accuracy. Every attempt to say something is a success, even if the word sounds different.
Read picture books together every day, but not as an exam: instead of asking “what’s this?”, it is better to tell, show and leave the child room to fill in a word. Sing songs with actions in which the child can finish a word or show a movement.
What to avoid
A few things parents do in good faith hinder more often than they help.
Forcing the child to speak. “Say ‘give’ nicely and you’ll get it” turns a conversation into an exam. A child who says little usually knows they speak badly, and pressure discourages them from trying.
Constant correction. Instead of “we don’t say ‘tat’, we say ‘cat’”, it is better to repeat the word correctly without comment: “Yes, a cat. The cat is sleeping.”
Guessing everything before the child tries. If an adult always knows what the child wants, the child has no reason to speak. It is worth waiting a moment longer now and then.
A screen instead of conversation. A cartoon talks at a child but does not talk with them. According to WHO guidelines, children aged 3–4 should spend no more than an hour a day in sedentary screen time, and time spent sitting still is better spent reading and telling stories with an adult.
Waiting for it to pass on its own. This is the most common mistake. Even if the child eventually catches up, a consultation takes nothing away, and if they do not, early support makes a big difference.
A three-year-old who says little at preschool
Parents often wonder whether to hold off on preschool until the child starts talking. Preschool can help, though: the child is surrounded by peers who talk and has more situations in which speech is useful. It is important that the teachers know about the difficulty, understand the child’s gestures and do not force them to speak in front of the group.
In a mixed-age group, typical of Montessori preschools, younger children listen to older ones who speak in full sentences, and the older ones are happy to explain, show and name things. Montessori language materials start by naming concrete objects the child can pick up, and the teacher gives the word when the child is interested in the object. What life in such a group looks like is described in the article on mixed-age groups in Montessori.
Preschool does not replace a speech-language therapist, however. Cooperation works best: the parent passes the specialist’s recommendations on to the teachers, and the teachers tell the parents what they see in the group.
FAQ — parents’ questions about a three-year-old who isn’t talking
How many words should a 3-year-old say? The CDC list for three years gives no word count; instead it describes what the child does with speech: converses over several exchanges, asks questions, speaks clearly enough for others. A three-year-old who says single words clearly differs from this picture and needs a speech-language assessment.
Do boys really talk later? According to data cited by ASHA, late language emergence affects boys about three times as often as girls. That does not mean you can wait longer with a boy — the criteria for a consultation are the same.
Will a child who understands everything start talking on their own? Many will: according to ASHA, about 50–70% of late-talking children catch up with their peers, and good understanding and gestures improve the chances. At the outset, though, it is impossible to predict which child will catch up, so a consultation and regular monitoring are needed.
Is not talking at three a sign of autism? Not necessarily. Many children who say little do not have autism. It is worth paying attention to eye contact, response to their name, pointing, interest in other children and pretend play, and talking to a doctor if in doubt.
My three-year-old used to say a few words and has stopped. What should I do? According to the CDC, losing skills the child once had is a signal to talk to a doctor straight away, without waiting for the next check-up. It is worth noting which words the child used to say and when they stopped using them.
What if the doctor says to wait? You can ask for a referral for a hearing test and to a speech-language therapist, or book a therapist yourself. An assessment does no harm to a child who will catch up, and for a child who will not, it gives earlier access to help.
Final thoughts
A three-year-old who does not talk but understands everything has an important asset on their side: understanding and the wish to communicate. It is a good sign, but not a reason to wait. What helps them most today is a hearing test, a speech-language assessment and adults who talk with them patiently, respond to every gesture and leave them time to answer.
