Children who stutter are imitating a stuttering parent or relative.

Stuttering is a genetically-influenced condition: most of the time, if there is one person in a family who stutters, there will be another person in the family who also stutters.

Forcing a left-handed child to become right-handed causes stuttering.

Stuttering varies significantly over time: Sometimes, people will have periods in which the stuttering appears to go away, only to have it return. This variability is normal.

Labeling a child as a stutterer results in chronic stuttering.

People who stutter often try to avoid stuttering, perhaps by trying to speak quickly, by forcing through moments of stuttering, or by not speaking at all when they fear that they might stutter.

Stuttering is caused by bad parenting.

Stuttering is associated with differences in the brain; it is not just a behavior that children learn or pick up from listening to other people who stutter.

Stuttering can begin gradually and develop over time, or it can appear suddenly.

Stuttering is more common among males than females. In adults, the male-to-female ratio is about 4 to 1; in children, it is closer to 2 to 1.

Stuttering usually begins in childhood, between the ages of 2 and 5 years.

People who stutter are less intelligent or capable.
