This was a book that all of my friends recommended that I get if I was planning on going back to work - which I am. I would have to say that this book provided a lot of insight for a first time mom like myself. Funny thing is, that this is mostly common sense. The philosopy is very similar to what my parents did with me when I was a baby.It takes a few sleepless nights to get your baby on the schedule - but it does work. Our son is 7 wks old and we started doing this schedule at about 1 month old. He sleeps anywhere from 6 - 8 hrs at a time at night now. He did wake up at about 3 AM during his 6 wk growth spurt. I anticipate that we will continue to be thrown curve balls regarding his schedule.Key point, this book provides a great guideline for each parent to establish a schedule that works for their child. I have a more flexible schedule and find that I have really reached a comfort level with it.
