Stuttering is a communicative disorder that affects an estimated 5.19% of children. Although approximately 71.4% of children whose stuttering onset is in the preschool years exhibit spontaneous recovery within two years after first reported onset, there remain a significant number of children who require fluency intervention. Given the potential for negative long term social and communicative consequences due to persistent stuttering, there is a consensus among speech-language pathologists that stuttering should be treated early. However, the longer a child's stuttering persists, the less likely the child will spontaneously recover.
