Talk with your baby before baby can talk with you. baby-signing: a complete guide is an innovative addition to the successful amazing baby[trademark] range of books. Amazing baby[trademark] and TinytalkUK believe that language helps us to make sense of our world. Babies understand so much before they can talk. Reading books together and using sign language encourages early word play - babies that understand and are understood are happy babies! Sign language provides a way for babies to tell others what they want and what they are thinking about.
