It is not uncommon for children between the ages of 2½ and 4 to present with typical disfluencies (e.g, whole word repetitions, easy, part-word repetitions). These typical disfluencies may come and go and are usually a sign that the child is learning to use language in new ways. Most children who demonstrate disfluencies prior to the age of 4 will recover without intervention. Children who begin to stutter after the age of 4 are at greater risk for persistent developmental stuttering.
Risk factors for persistent developmental stuttering:
- Family history of stuttering
- Child is male
- Stuttering has continued for 6 months or longer
- Stuttering types and severity change over time
- Presence of other speech or language disorders
