Query: Not very helpful for infants

I didn't find much usable information in this book. It basically said I can let a baby cry a little or cry a lot, but didn't give me any good steps for teaching him how to get to sleep and stay asleep on his own. I've since read a much more helpful book titled, "The Baby Sleep Solution" that does give good, concrete steps to follow.
