The basic premise is to get your baby on a flexible routine of eat, play, sleep, following their cues. She believes in teaching baby to self soothe and learn to fall asleep on his own in his own bed, but with the parents' help. Leaving baby to cry alone breaks trust, so the parent is there along the way to soothe when needed.
There is also an online message board where you can get your questions answered. They will look at your routine & help you tweak it and problem shoot with you to solve sleeping, eating, and other problems.
