Preschooler Stuttering and Unclear Speech: What's Normal

Why speech gets bumpy at 2 to 5

• Between about 2 and 5, language grows so quickly that a child's ideas often run ahead of their mouth. Repeating words, starting over and pausing are common.
• Some sounds are hard for a long time. Unclear speech at 3 or 4 is often still in the normal range.
• See the toddler talking guide for earlier ages and the preschool milestones guide.

Normal disfluency vs. stuttering

• Typical disfluency: repeating whole words or phrases ("I want - I want - I want the ball"), "um" and "uh," revising sentences. Usually relaxed, and the child doesn't seem to notice.
• Stuttering tends to look like: repeating parts of words ("b-b-b-ball"), stretching sounds ("ssssun"), or getting stuck with no sound coming out. Some children blink, tense their face or look away when stuck.
• Stuttering usually starts between about 2 and 6, sometimes suddenly. It can come and go for weeks at a time.
• Many young children who start stuttering stop on their own within a few years, but some don't, and early speech therapy works well.

How to help a child who stutters

• Slow your own pace. Speak a little slower and pause before answering. This lowers pressure without telling them to slow down.
• Wait patiently. Keep eye contact, don't finish their words, and don't say "relax" or "take a breath."
• Listen to what they say, not how they say it. Respond to the message.
• Make time for one-on-one talk each day, without rushing or screens.
• Reduce quick-fire questions. Comment more and ask less.
• If they notice, name it simply: "That word got stuck. That happens sometimes. I'm listening."
• Let teachers, grandparents and siblings know the same approach.

Speech sounds and clarity

• Rough guide: by about 3, familiar adults understand most of what a child says; by about 4, most people, including strangers, understand them most of the time, even with some sound errors.
• Earlier sounds include p, b, m, d, n, w and h. Some sounds, like r, l, s, th and z, can take until age 5 to 7 or later.
• Help by repeating back the correct version naturally: "Wabbit? Yes, a rabbit!" Avoid making them repeat it.

More than one language

• Bilingual and multilingual children may mix languages or show more pauses while sorting words. This is normal and doesn't cause stuttering. Keep using your home languages.
• A speech-language pathologist should look at a child's skills across all their languages.

When to check in

• Mention it at the next checkup, or ask directly for a speech-language evaluation, if stuttering has lasted more than about 6 to 12 months, is happening more often, comes with tension or struggle, makes your child avoid talking or seem upset, started after about age 3 and a half, or there's a family history of stuttering.
• Also check in if most people can't understand your child by about 4, or if speech seems to be going backward.
• A hearing check is often a good first step. From age 3, your local public school district offers free evaluations; under 3, contact early intervention.
