I have read many sleep books and this was my favorite. She's funny, honest and provides a lot of different options for parents. I know a lot of people are opposed to letting their child cry, but she is up front about the fact that there are very few changes you can make to improve sleep that won't result in SOME crying. I also liked that she covered different age ranges and provided a lot of detail about scenarios you may encounter when trying to improve your child's sleep. You can't go wrong for $2 on 鶹 kindle!
