Query: Don't waste your money

Sorry, but this book didn't really have any revolutionary advice, and seems to keep making the same points over and over. Buy Dr. Spock where you get advice on just about everything, instead of wasting your time & money on this one. We didn't find any miracle cures for crying here, and lucky for us, our sweet baby grew out of his crying fits anyway.
