Children often go through a period of stuttering during their preschool years, yet most children recover and develop fluent speech. For children who persist, stuttering often makes it difficult for them to say what they want to say the way they want to say it. With support from the National Institute on Deafness and Other Communication Disorders at the National Institutes of Health, we are dedicated to understanding how stuttering, along with the potential for adverse impact, develop in young children. This research will bring new insight into the development of stuttering leading to improved outcomes for children who stutter.
