I was given this book, when my baby was born. Worldwide, health professionals have spoken out against this book. It also has a rather thinly disguised conservative christian agenda.As for the little tests at the end of each chapter; its just plain patronizing. You know your baby best. I urge you not to follow this regimen for the safety and health of your baby. I would have passed this on, or left it in my apartment building's recycle room, but I threw it in the trash. It is very dangerous. By all means have structure and schedule. But do not ignore your baby's needs. Those needs are not manipulative. And it is your job and your privilege to respond.
