Research shows that babies can communicate through sign language as early as ten months, long before they can communicate through speech. Studies have also shown that babies who have learned to sign have higher IQs and more extensive vocabulary. This book includes a DVD that will teach parents and babies to sign simple words. The book was created by child development experts and Emmy Award-winning producers and animators.
