This book talks about the different gestures and sounds that babies make and how these are signals to parents that they are trying to communicate. For example, we would usually dismiss a baby's first smile as a reflex, that it did not mean anything. The authors, however, explain otherwise. This first smile and eye contact is a baby's first attempt to try to connect with his/her parents. The book goes on further to explain the different cries and how to interpret whether baby needs a diaper change, is hungry, or is in pain. Other chapters include baby's hand gestures and the meaning of baby babble. This is a useuful book since not only does it talk about the things babies do, but also gives suggestions to parents about toys and games that encourage interaction. It also introduces parents to the pros and cons of teaching baby sign language. All in all, this is an excellent book for would-be parents and parents alike.
