I am a mother to a 22 month old who, thanks to this book, has always been a good sleeper! I was an avid reader on the topic before labor and delivery because I had heard too many horror stories about moms setting bad habits for their newborns and then paying the price...in fact, believe it or not, I still hear those stories! But, this book was the most practical, science-based and humane way to help your child sleep well. The idea is that the baby is deprived of development if not allowed to sleep. That was key to me. The baby doesn't have the instinct to go to sleep when tired since she/he is so eager to see you and spend time with you. But, if you can handle about 20-30 minutes of crying the first 2-3 nights, you will be able to have years of good sleeping babies and toddlers. I recommend this book to all new parents!!!!
