Query: HORRIBLE

Please do not buy this book. It will make you doubt your instincts. I'm all for Eating, Play, then Sleep, but you can get that from much better books such as the "Baby Whisperer." Waking your baby up is also a bad idea. Sleep is Nutrition for babies as supported by numerous case studies in another GREAT baby book "Healthy Habits, Happy Child."
