This book and the tips within has been my life saver with my three kids. The first two slept through the night from very early and are altogether happy, balanced kids. Now with my third baby, I am finally applying most of the concepts and it's working wonders. Don't try to get your baby into a rhythm from day one though, like Tracy suggests. Take your time, slow down, and when you feel your baby has its own inner rhythm, then apply EASY. It does work. It's the book I always recommend and have given to all my pregnant friends.
