I bought this book because so many people seemed to rave about it. But, in my case, it failed dismally to live up to my expectations. My daughter is the type of child Weissbluth labels as "extremely fussy" and "difficult" (which is true, although I would describe it as "spirited" and eager to laugh when pleased and shout when not). She sleeps 12 hours straight at night but refuses to take naps. Weissbluth's advice - basically a fancy way of saying "let her cry it out" (for up to an hour for each nap! - that's 3 hours a day of "crying it out"). Don't buy if if you are the type of parent who refuses to let your child cry endlessly. The book also contains lots of inconsistencies - for example, he states as a fundamental principle "never wake a sleeping baby" but 5 pages later says to "wake a baby up at 7 am" and "wake a baby up after a 1 hour nap". I'm sure his principles work for many children but certainly not mine.
