Don't ask your child to slow down when he speaks. Try to convey to your child that you have plenty of time and are not in a hurry. Model a relaxed rate of speech. A rushed type of speech is a temporary phase that can't be changed by orders from the parent. Don't label your child.
Labels tend to become self-fulfilling prophecies.
Don't discuss your child's speech problems in his presence. Ask other adults not to correct your child's speech. Share these guidelines with baby sitters, teachers, relatives, neighbors, and visitors. Don't allow siblings to tease or imitate your child's stuttering. Help your child relax and feel accepted in general.
