As with each of these books on helping infants sleep, the information from author to author is so contradictory. The book spends too much time on his findings and work he's done instead of getting to the meat of the matter - how to help children "learn" to sleep. As a sleep deprived parent, I don't have the time to wade through all the superfluous info...I need the goods! When I finally did get to the information I needed it was convoluted and confusing. It did make some valid points ( don't wake a sleeping baby and routine, routine, routine). To the author's defense, he encourages the reader to read the book PRIOR to having the baby because that's about the only time you have to read. Once the baby comes, forget it.
