Stuttering is caused by bad parenting.

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

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

Identifying or labeling a child as a stutterer results in chronic stuttering.

When people stutter, they feel like they have lost control of their speech mechanism.

Stuttering is caused by emotional trauma.

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

People who stutter can overcome the burden of stuttering and live full lives regardless of whether or how much they stutter.

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 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.
