It often starts overnight. On Tuesday your three-year-old was chatting away. On Wednesday it is "I-I-I-I want the... the... the red one". You catch yourself holding your breath every time they start a sentence.
First, the good news, because you should hear it before anything else. Most young children who start stuttering stop on their own.
Now the useful part, because "most" is not "all", and there are clear signs that tell you which way things are going.
Why toddlers stutter
Between two and five, language grows faster than at any other time. A child's ideas, vocabulary and grammar race ahead, and the mouth has to keep up with a brain that suddenly has a lot more to say.
Some bumps are expected. Every young child repeats, restarts and says "um" while they work out a sentence. For some children, the bumps become frequent and start to look different. That is stuttering, and it often appears in a child who was speaking fluently before.
You did not cause it. Stuttering is not caused by parenting, stress, a new sibling or anything you said. Stressful moments can make it more noticeable, but they are not the source. It has a strong genetic link and is about how the brain coordinates speech.
Normal bumpy speech vs stuttering
Typical disfluency (what most children do):
Signs of stuttering:
The last two matter most. They show that your child has noticed the stutter and is fighting it.
How many children grow out of it?
Estimates vary, but roughly 75 to 80% of young children who start stuttering stop within a few years, with or without therapy. Some studies put it higher.
That still leaves one child in five or so who keeps stuttering. Researchers have found a few things that make that more likely:
None of these mean your child will keep stuttering. They mean it is worth getting advice sooner rather than later. See the ASHA overview of stuttering for more.
When to call a speech therapist
Get an evaluation if any of these are true:
1. Your child has been stuttering for 6 months or more.
2. They started stuttering at three and a half or later.
3. You see tension, struggle or avoidance.
4. Someone in the family still stutters as an adult.
5. It is getting more frequent, or it is upsetting your child or you.
You do not need to tick all of them. One is enough. An evaluation does not commit you to therapy. Often it ends with advice and a plan to check again in a few months.
What to do at home
These habits help whether or not your child ends up in therapy. They are also what a speech therapist will likely suggest first.
What therapy for young children looks like
For preschoolers, therapy usually works through the parent. Two approaches are common:
Your therapist will choose based on your child's age, how long they have stuttered, and how they feel about it. Both approaches rely on you doing a small amount at home, often.
FAQ
My child stutters some days and not others. Is that normal?
Yes. Stuttering often comes and goes in waves, sometimes for weeks at a time. Track it over months rather than days.
Should I tell their preschool?
Yes. Ask staff not to finish words or tell your child to slow down, and to give them time in group talk.
Will my child stutter as an adult?
Most children who start in the toddler years do not. If it continues past school age, therapy helps many children speak more easily and, just as important, feel confident talking.
Is stuttering linked to anxiety?
Anxiety does not cause stuttering. But children who stutter for a long time can become anxious about speaking, which is one reason not to wait if you see struggle or avoidance.
