It has been my experience that most parenting books give you just enough information to make you mad. It’s like they are dumbed down. I found Babywise and Secrets of the Baby Whisperer hard to implement. Finally I found a book on sleep that I can sink my teeth into. It not only gives the how but the WHY. It often explains both sides of an issue and isn’t particularly one sided, although it does focus on sleep training. The chapters are broken down into ages, going through adolescence! So far I’ve read the birth through four month chapter. Sleep is going much better for us now that I have the information I need.
