I've heard that there are a number of different types of stutters. What are the most common types?

The most common types of stutters include developmental, fluency, and mixed. Developmental stuttering is a type of stutter that occurs in children who have not yet learned how to control their speech. Fluency stuttering is a type of stutter that affects adults who have been speaking for many years but still experience occasional blocks. Mixed stuttering is a combination of both developmental and fluency stuttering.
