Have fun making Mouth Sounds while encouraging speech and language development with your young children. Making Mouth Sounds All Day Long was written for you to read to your young children again and again to expose them to speech sounds and vocabulary. The text in the story was written to focus on the early to later developing speech sounds in the English language. Follow the adorable toddlers through a typical day of play and see how the family puppy experiences the same events, but in a different way.
