Typical Disfluency vs. Stuttering: What’s the Difference?
According to ASHA’s Practice Portal on Fluency Disorders, typical disfluencies usually involve whole-word or phrase repetitions (“I want — I want that”) and interjections (“um,” “like”), without physical tension. True stuttering more often involves repeated sounds or syllables (“b-b-ball”), prolonged sounds (“mmmmy turn”), or blocks where no sound comes out at all — sometimes with visible tension in the face, jaw, or body.
When Does Stuttering Usually Start?
Stuttering typically begins early: roughly 95% of children who stutter start before age 4, with an average onset around 33 months. Onset can be gradual or sudden.
Risk Factors for Persistent Stuttering
Most young children who show some disfluency do not go on to develop a lasting stutter. Research identifies several factors associated with higher risk of stuttering persisting:
- Being male
- Onset at age 3½ or later
- Disfluency lasting longer than 6–12 months
- A family history of stuttering
When to See an SLP in Edmonton
It’s reasonable to book a speech-language evaluation if your child has been stuttering for more than six months, shows physical tension or struggle when talking, seems frustrated or aware of their stuttering, or has a family history of stuttering. You can self-refer to AHS Preschool Speech and Language Central Access for children under five, or reach out to a private clinic for a faster first appointment.
What Parents Can Do at Home
While you wait for an evaluation (or alongside it), general supportive strategies include: slowing down your own rate of speech rather than telling your child to slow down, giving your child your full attention without rushing them or finishing their sentences, and keeping the focus on what they’re saying rather than how they’re saying it. These strategies won’t “cure” stuttering, but they help reduce communication pressure at home.
Frequently Asked Questions
Is it normal for my toddler to repeat words?
Yes — whole-word and phrase repetitions without tension are a common part of typical speech development between ages 2 and 4.
Will my child outgrow stuttering?
Many young children do. But because risk factors like family history, longer duration, and later onset make persistence more likely, an evaluation can help you understand your child’s individual picture rather than guessing.
Does anything cause stuttering?
Stuttering is a neurodevelopmental condition, not something caused by parenting or a stressful event, though stress can sometimes make existing stuttering more noticeable.
When should I book an evaluation?
If disfluency has lasted more than six months, involves visible tension, or your child seems bothered by it — or simply if you’re worried — an evaluation gives you clarity either way.
