Stuttering in Children

What is stuttering in children?

Stuttering is a disruption in the flow of speech. It is not a problem with knowing what to say.

The DSM-5-TR term is childhood-onset fluency disorder.⁠³ "Stuttering" is the usual word in the US and "stammering" in the UK — they mean the same thing.

Why did my child suddenly start stuttering, and at what age?

Because that is how it usually begins. In a study that followed more than 1,600 Australian children from infancy, onset came suddenly, over one to three days, for about half of the children who began stuttering by age three, and it seemed to be associated with rapid growth in language.⁠⁶

ASHA's guidance puts the average age of onset at around 33 months, with roughly 95% of children who stutter beginning before age four.⁠¹ In a community study, a start before age three was not unusual and was not linked to language delay or to social or environmental factors.⁠⁶

Did I cause my child's stuttering?

Nothing a parent did or did not do causes stuttering. Not talking too fast, and not correcting speech: emotional problems and parenting style do not cause it, and its causes are thought to include genetic and neurophysiological factors. Stress, family dynamics and a fast-paced lifestyle can make disfluency worse without being the cause.⁠¹

Anxiety does not cause stuttering either. Stress and anxiety can make disfluency worse, and stuttering can bring increased social anxiety⁠¹ — but the direction people assume is backwards.

What does stuttering look like in a child?

Repetitions, prolongations, and blocks

Three core features, and they can occur in the same child.

• Repetitions of sounds, syllables, or whole words — "c-c-c-can I have it"
• Prolongations, where a sound is stretched out — "mmmmmy turn"
• Blocks, where speech stops entirely. The mouth may be in position and nothing comes out.

Alongside these, some children develop physical tension in the face, jaw, or neck; secondary behaviors such as blinking, head movements, or tapping; and avoidance — swapping words, dodging certain sounds, not speaking up, not ordering for themselves.⁠¹

What is covert stuttering?

Covert stuttering is stuttering that almost nobody knows about, because the person has become skilled at hiding it. They swap words mid-sentence, talk around what they meant, stay quiet, or avoid situations entirely.⁠¹

Hiding stuttering can begin as early as the preschool years, though it is more common later in childhood and beyond, and efforts to conceal it are linked to more distress and lower quality of life.⁠¹ A child hiding stuttering this way can seem quiet rather than disfluent, so it is worth knowing this exists.

Normal disfluency vs stuttering: how to tell

Some disfluency is normal in young children. What distinguishes stuttering is the type of disruption, the effort, and the tension.⁠¹

Do kids grow out of stuttering?

Probably — and that is exactly what makes the next section matter. ASHA's practice portal cites estimated recovery rates, with or without intervention, of approximately 88 to 91 percent; counting children's own reports of recovery, the rate may be closer to 60 percent.⁠¹

Those are good odds, and they are the reason waiting can feel reasonable.

Should you wait and see if stuttering stops?

No: it is not possible to tell with certainty at onset which children recover.⁠¹

The old reasoning was sound as far as it went: most children recover, so intervening in every case looked like overtreatment. What has changed is the evidence on the other side of the scale. Treatment for preschool children now has randomized trial evidence, and a 2005 trial concluded that its results "support early intervention for stuttering."⁠²

What raises the chance stuttering will persist?

These are not predictions — they are factors a clinician weighs when deciding how soon to act.

• Family history of persistent stuttering. Children with a family history of stuttering are about 1.9 times as likely to keep stuttering as children without one.⁠¹
• Stuttering continuing beyond six to twelve months from onset, or not improving over several months⁠¹
• Later onset, at age 3½ or older⁠¹
• Co-occurring speech or language difficulties, or slower language development⁠¹
• Being a boy: boys are more likely than girls to keep stuttering⁠¹

None of these means a child will not recover. They are reasons to assess sooner rather than later.

What not to say to a child who stutters

These are the standard well-meaning responses, and they generally make the moment harder.

• "Slow down" — the child is not going too fast, they are stuck
• "Take a breath" — this adds a task to something already effortful
• "Think about what you want to say" — they know what they want to say
• "Start again"
• Finishing their sentence — even helpfully. Especially helpfully.
• Telling them to relax

Why these backfire: they draw attention to the moment, add pressure, and imply the child is doing something wrong that they could correct if they tried harder. Speech-language pathologists coach families to focus on what a child says rather than how they say it.⁠¹

How to help a child who stutters at home

Slow your own speech. Not dramatically — just unhurried. Reducing their own speaking rate is one of the changes speech-language pathologists coach families to make.⁠¹

Pause before you answer. A short gap before you reply makes the conversation feel less hurried.

Keep normal eye contact. Looking away signals discomfort. Staying present signals that this is fine.

Respond to what they said, not how they said it.⁠¹

Reduce competing demands. One person talking at a time, fewer rapid-fire questions, fewer situations where they have to compete to be heard.

Make room. Regular unhurried time to talk without an audience.

If they get frustrated, name it kindly. For a child who is clearly aware, "that word was tricky — I'm listening" is better than pretending nothing happened.

Speech therapy for stuttering: what works

Speech therapy is the treatment, and the approach depends on age.

What is the Lidcombe Program?

The Lidcombe Program is a parent-delivered, clinician-guided treatment for preschool stuttering. A parent is trained to comment on the child's stutter-free and stuttered speech, guided by a speech-language pathologist.⁠¹

A randomized controlled trial published in the BMJ in 2005 concluded that the results "support early intervention for stuttering" and that the program "is an efficacious treatment for stuttering in children of preschool age."⁠² A 2021 Cochrane review of non-drug treatments for stuttering in children six and younger found four eligible randomized trials, all testing the Lidcombe Program against a wait-list; it lowered how often children stuttered, though the review rated that evidence very low certainty.⁠⁵ Other approaches used with young children coach families to change their own speech and the child's communication environment.⁠¹

Stuttering treatment for older children and adults

Therapy typically combines techniques for producing speech more easily with work on the tension, avoidance, and anxiety that accumulate over years. ASHA's guidance is that treatment should consider the emotional and thinking reactions to stuttering as well as the stuttering itself.⁠¹

Stuttering, anxiety and school

Anxiety does not cause stuttering, but stuttering can produce it — particularly once a child becomes aware and starts anticipating difficult words and difficult situations. Increased social anxiety is one of the effects of stuttering that ASHA lists.⁠¹

Common accommodations: not being made to read aloud without choice; extra time for verbal answers; being allowed to finish without interruption; alternatives to oral presentations, or advance preparation; an agreed plan for how the teacher will respond; and addressing bullying directly, because children who stutter may be more likely to be bullied.⁠¹

Tell the school what helps, including not finishing your child's sentences. → IEPs and 504 plans

Is the goal always fluency?

No. ASHA's guidance is that increasing fluency may not be a goal for an individual, or may be only one part of a broader approach, and that goals may focus on reducing negative reactions to stuttering and difficulties communicating in different speaking situations.⁠¹

Someone who stutters openly, speaks up, orders their own coffee, and pursues what they want is doing better than someone who is fluent because they avoid speaking: efforts to conceal stuttering are linked to more distress and lower quality of life.⁠¹

This matters practically for a child. People can have negative feelings about using speech modification strategies, which often make their speech sound different from natural speech.⁠¹ It is worth asking any therapist what their goals are and how they think about this.

When to see a speech therapist for stuttering

Arrange a speech and language assessment if:

• Stuttering has continued for more than six months
• There is a family history of persistent stuttering
• Your child shows tension, struggle, or frustration
• Your child is avoiding words, situations, or speaking
• You are concerned — that is a sufficient reason on its own

Under three in the US, a parent can refer their own child to early intervention without a doctor's referral, and the evaluation is free.⁠⁴ From three, request a school evaluation in writing.
