Ezzo is not qualified to give advice on babies which to me is a problem. I don't believe in getting babies into routines when they are that small so I was never going to agree with much of what he has written anyway. Babies don't cry to manipulate people ... they cry because they need something from you and those cries cannot go unanswered. A baby cannot be spoilt from being picked up when it cries. They don't understand why you are leaving them to cry so the concept of "training" them doesn't quite wash.

That said, if people have read his books and found some tips which were helpful and worked for them, then well and good. I think it might be very much a case of take what you can use and leave what you can't.
