This is an extremely thought-provoking book. It offers a different way of parenting for those people who are not sure about time out etc, but perhaps can't quite put their finger on what bothers them about it. The idea that praise and punishment are two sides of the same coin and that they are equally damaging is hard to take, but AK's argument, to me, was very persuasive.
Unfortunately I've found it extremely hard to break the praising habit. It feels like you are not being appreciative. Especially when your child is v small and everything they do is new and exciting, it is hard not to say well done, good boy etc. That is one area that the book falls down a little - there aren't very many examples of what you can do instead of praising.
Also, I've found that it brought out some strong feelings about my own childhood and how my parents interacted with me - I don't want to make the same mistakes and hopefully reading this book will help me raise a confident son, who knows that he is always loved no matter what.
