Speech delay in toddlers: what it means, red flags and how to get support
If you have found yourself searching "my toddler isn't talking", you are in very good company. Worrying about a child who seems slow to speak is one of the most common experiences of the toddler years, and the anxiety makes complete sense. Words feel like a window into your child's inner world, and when that window seems slower to open than you expected, it is hard not to worry.
Here is what matters most right now: many children who are late to talk catch up entirely, and for those who need support, starting early consistently produces the best outcomes. This guide will help you understand what the milestones look like, what to watch for, and when and how to ask for help.
What is speech delay?
Speech delay means a child is using fewer words, or producing sounds and words less clearly, than is typical for their age. It is one of the most common developmental concerns in the toddler years, affecting roughly one in five children at some point.
Speech delay is not a diagnosis in itself. It is a description, a sign that something may need a closer look. The important next step is always to understand why, which is what a proper assessment is for.
Speech delay and language delay: what is the difference?
These terms are often used interchangeably, but they describe different things. Understanding the distinction will help you have clearer conversations with your GP, health visitor, or speech and language therapist.
Speech is the physical act of forming and producing sounds, words, and sentences clearly. A child with a speech delay may have difficulty producing certain sounds or be hard for others to understand, even when their understanding of language is strong.
Language covers two areas:
- Expressive language: the words and phrases a child uses to communicate
- Receptive language: what a child understands, including following instructions, responding to their name, and pointing when asked
A child can have a delay in one area without the other, and this distinction shapes what might be going on and what help is most useful.
Does your toddler understand you?
One of the first things a clinician will ask is whether your child seems to understand language even if they are not speaking much. A toddler who follows simple instructions ("get your shoes", "give it to daddy"), turns reliably when their name is called, and points to share things they find interesting is demonstrating strong receptive language, even if their spoken words are few.
This matters. A child with limited expressive language but strong comprehension is in a meaningfully different position from a child with delays in both understanding and speaking. Both situations are worth getting assessed, but delays across both expressive and receptive language are a stronger signal that assessment should not wait.
That said, even strong comprehension does not mean waiting is fine indefinitely. If expressive language is significantly behind where it should be, an assessment is always the right step.
Speech and language milestones at 12 to 36 months (AAP 2022)
The American Academy of Pediatrics updated its developmental milestone guidance in 2022. These are the key language markers for toddlers:
| Age | What to expect |
|---|---|
| 12 months | At least 1 word beyond "mama" and "dada" |
| 15 months | At least 3 words |
| 18 months | At least 6 words |
| 24 months | At least 50 words; using two-word phrases ("more milk", "daddy go") |
| 36 months | Simple sentences of 3 or more words; mostly understood by unfamiliar adults |
If your toddler is not meeting one or more of these markers, that is a reason to ask for a professional assessment. It is not a reason to panic, but it is a reason to act rather than wait.
Why do some toddlers have speech delay?
There are several possible causes, and a proper assessment will help identify the reason or rule things out systematically.
Late talking (idiopathic delay)
Some children are simply later to produce words, with no identifiable reason. Many late talkers do catch up, particularly those whose comprehension is strong and who show no other concerns. A "watch and see" approach can be appropriate for children who are just behind a single milestone, but it is not a substitute for assessment when delays are significant.
Hearing loss
This is the most commonly missed cause of speech delay, and it is the single most important thing to rule out. A child who cannot hear clearly cannot learn to reproduce the sounds around them. Hearing loss in toddlers can be mild and easy to miss, as children become skilled at picking up visual cues and context. Every child with a speech delay should have a formal audiology assessment.
Ear infections and glue ear
Recurring ear infections or persistent fluid behind the eardrum (glue ear) cause fluctuating hearing loss. Months of muffled hearing during critical language-learning windows can have a real impact on speech development, even when hearing appears normal at other times.
Oral motor difficulties
Some children have difficulty coordinating the muscles of the lips, tongue, and jaw needed to form words clearly, even when their understanding of language is strong.
Prematurity
Children born prematurely may reach milestones later than their birth-date peers. Milestones are typically assessed on a corrected age (adjusted for how early they were born) until around age 2.
Autism spectrum disorder
Language delay is one of several early features associated with autism. Other signs that may appear alongside it include limited or inconsistent eye contact, not pointing to share interest in things, not imitating actions or sounds, and less interest in other people's faces. If you have any concerns about your child's social communication as well as their speech, raise both together when you seek help.
Developmental language disorder (DLD)
DLD is a significant, lasting difficulty with language that is not explained by another condition. It is more common than many parents realise, affecting around 1 in 14 children. A child with DLD may have typical hearing and no other diagnosis, and still find language persistently difficult.
Bilingualism
Growing up with two or more languages does not cause speech delay. Bilingual children may split their vocabulary across two languages, so counting words in one language alone can underestimate their total vocabulary. When assessing a bilingual child, a speech and language therapist will consider all languages together. If your child is bilingual and you are raising a concern, mention both languages from the start.
Hearing: rule this out first
It is worth saying clearly and separately. If your child is not talking as expected, a hearing test is not optional. It should happen at the same time as, or before, any other assessment. Hearing loss is the most common missed cause of speech delay, and in most cases it is treatable.
A formal audiology assessment is what is needed, not a bedside hearing check or a parent-reported screen. When you speak to your GP or health visitor, ask specifically for both a speech and language therapy referral and a hearing assessment. You can request both at the same appointment.
What you can do right now
While you are waiting for an appointment, or even before you have made one, there is a great deal you can do day to day. These strategies are backed by strong evidence and are appropriate for all toddlers, not only those with concerns.
Talk constantly and narrate everything
Language grows from exposure. Keep a running commentary on what you are doing together. "I'm putting on your jacket. First this arm, then that arm. There we go." Your toddler does not need to respond for this to be useful. The input builds the foundation.
Read books together every day
Even short books repeated many times over are valuable. Your toddler will begin to anticipate words and fill in gaps. Point to pictures as you name them, and let your child turn the pages at their own pace.
Sing songs and nursery rhymes
The rhythm, repetition, and predictability of songs help cement words and sounds in a way that ordinary conversation alone does not. Action songs like "Wheels on the Bus" add movement and make language physical.
Respond to every communication attempt
When your child points, reaches, vocalises, or tries a word, respond warmly and expand on it. "Oh, you want the cup? Here's your cup." This back-and-forth loop, where the child communicates and an adult responds with warmth and language, is one of the most powerful drivers of speech development.
Keep screen time limited
The AAP recommends avoiding screens other than video calling for children under 18 months. Between 18 and 24 months, keep screen time limited and co-view where possible. Passive screen time displaces the interactive, back-and-forth talk that builds language.
Use short, clear sentences
Pitch your language just above your child's current level. If they are using single words, try two- or three-word phrases. "Ball gone" or "Dog sleeping" rather than a long running explanation. This gives them a slightly extended model to reach for.
Comment rather than quiz
Too many questions can feel like pressure, especially for a child already finding language hard. Describe and comment rather than asking. "That's a dog" rather than "What's that?" "You're eating the banana" rather than "What are you eating?" This keeps communication low-pressure and natural.
Red flags: when to act without delay
Some signs mean you should seek an assessment promptly, rather than waiting to see if things improve. Contact your GP or health visitor now if any of the following apply:
- Your child has lost words or skills they previously had. Regression of any kind needs urgent review.
- Your child is not babbling by 12 months.
- Your child has no words at all by 16 months.
- Your child has no two-word phrases ("more milk", "daddy go") by 24 months.
- You have any concern about your child's hearing.
- Your child does not make consistent eye contact, does not point to share things with you, or does not seem interested in other people's faces.
These are flags, not certainties. Noticing one does not mean the worst. But they are signals that say: ask now, not in a few months.
How to get help
Start by speaking to your GP or health visitor and asking for two things at once: a referral to Speech and Language Therapy (often called SALT or SLT) and a formal hearing assessment. You can request both at the same appointment and it is entirely reasonable to do so.
In many areas of the UK you can self-refer to Speech and Language Therapy without a GP appointment at all. The Talking Point website (talkingpoint.org.uk) has a postcode-based search to find your local service, as well as clear guidance on what an assessment involves and what to expect.
NHS waiting lists for SALT can be long. Referring early means your child reaches the front of that list sooner. You do not need to be certain there is a problem to ask for an assessment. If you are concerned, that is enough reason to ask.
If you would like to begin support more quickly, private speech and language therapists are available. The Royal College of Speech and Language Therapists (RCSLT) website has a register of accredited therapists searchable by location.
Early support changes outcomes
The evidence here is consistent and encouraging. Early speech and language intervention, when it is needed, makes a meaningful difference. The first three years of life are a particularly important window for language development, and support given during this period tends to be more effective than the same support given later.
The old advice to "wait and see until age 3" for significant delays is no longer what the evidence supports. For a child with meaningful expressive delay at 18 to 24 months, early referral is entirely appropriate and often the right call. For a child with delays affecting comprehension as well as expression, it is urgent.
Asking for help is not an overreaction. It is the most useful thing you can do.
Questions parents often ask
What counts as a speech delay in a toddler?
A speech delay means a child is using fewer words or producing sounds less clearly than expected for their age. According to AAP 2022 milestones, the markers to watch are: at least 1 word by 12 months, 3 words by 15 months, 6 words by 18 months, 50 words and two-word phrases by 24 months, and simple sentences by 36 months. If your child is not meeting one or more of these markers, it is worth asking for a professional assessment.
Does speech delay mean my child has autism?
No. Speech delay has many causes, most of which have nothing to do with autism. Common reasons include hearing loss, glue ear, late talking (where many children catch up), and developmental language disorder. Autism can be associated with speech delay, but autism also involves other features such as differences in eye contact, pointing, and social engagement. If you have concerns about both speech and your child's social communication, raise both with your GP or health visitor.
Is it more worrying if my toddler's comprehension is also delayed?
It is a stronger signal, yes. A toddler who has limited expressive language but strong comprehension (follows instructions, responds to their name, points to share things) is in a different position from one with delays across both understanding and speaking. Both situations warrant proper evaluation, but delays in both areas are a reason to seek assessment promptly rather than wait.
Will my toddler just catch up on their own?
Some children do. Late talkers with strong comprehension and no other concerns sometimes catch up by age 3 or 4 without intervention. But waiting on its own is not the recommended approach for significant delays, particularly beyond 24 months. Early support, when it is needed, consistently produces better outcomes than waiting. Asking for an assessment is not an overreaction; it is the right thing to do.
Does being bilingual cause speech delay?
No. Bilingualism does not cause speech delay. Bilingual children may split their vocabulary across two languages, so counting words in one language alone can make their vocabulary look smaller than it is. When assessing a bilingual child, a speech and language therapist considers total vocabulary across all languages. If your child is bilingual, mention both languages when you raise your concerns.
How do I get a referral to speech and language therapy?
In the UK, ask your GP or health visitor for a referral to Speech and Language Therapy (SALT), and request a hearing assessment at the same appointment. In many areas you can also self-refer; the Talking Point website (talkingpoint.org.uk) has a postcode search to find your local SALT service. NHS waiting lists can be long, so referring early gives your child more time. If you want to start sooner, the RCSLT website lists accredited private therapists.
