Query: This is a WONDERFUL book!

I've seen Baby Signs in action, not only within my own family, but also in the child-care center where my children have been enrolled part time. It is amazing to see true communication happening between adult and child at such young ages! They can express what they need ("juice," "snack", "out"), describe what they see ("big," "sad," "scary"), and share observations with those around them ("Birdie," "Airplane," "Ball") well before they can say the words. You can tell how empowered they feel at actually getting their ideas across. And the beauty of the book for parents is that it is full of information gathered in the authors' research about how creatively infants use Baby Signs, how the transition to words occurs, individual differences among babies, and LOTS of wonderful examples. The glossary of sign suggestions is helpful and the Baby Sign nursery rhymes are lots of fun. I can't think of another book that has made such a big difference in the lives of both my children.
