My mom gave me this book when my son was a couple months old, and I really felt it undermine my confidence in my own instincts. She is very anti-co-sleeping, a couple of places it seemed like she didn't even want you to hold the baby, her b-feeding advice is lousy, etc. The problem is she weaves that stuff in with really good stuff about listening to your baby and reading his signs, etc, but you can respond to your babies signs only if it's convenient for you. Sorry, I'm very bitter about this book. It led me astray for awhile before I learned about AP (which I was doing unknowingly before I read the babywhisperer). She glorifies "independence." What really makes me mad is this one story she told about a nursing toddler...arg, I won't even get started. I think this is a very dangerous book, because she talks a good game, but then the advice she gives is totally the opposite of what she says. Frankly I don't see much difference between the pick up put down method and controlled crying it out. Except maybe that p/u, p/d is even more confusing and upsetting to the baby. Sorry, this is kind of rambling. I'm so against any parenting book that advices you to go against your instincts.
