Both say right away, I had trouble finishing this book. Perhaps because he approaches things in an unconventional way. At first, I understood that he was to accept everything to the child, no prohibition (which bothered me). And finally, not at all. Everything is embroidered around the same concept: no need to give punishment to the child, no need to reward him. A happy medium for the harmony of the parents as the child without being permissive. Basically, this is a very communicative approach with the child, when given a penalty, the penalty is defined together. When a child does something wrong, it explains why it is not good (read the book to understand everything, I'm here very minimal). I am the father of a little boy of 20 months and I must admit that since I read that book, I apply the advice to my son and I can already see clear results. Obviously, 20 months is not involved in the punishment but he understands the explanations I gave him and did not begin his nonsense. I suggest reading this book to get an overview that still lack of concrete examples (the little that there is very nunuches, American). This book should be completed by reading "Effective Parents" (I am currently reading) by the same author and more concrete.
