I had heard of this book, so I decided to read it. It seems like some good ideas but I don't plan to implement it now. Baby girl doesn't really do anything I find countworthy at the moment - most things need to be stopped right away, like hitting the dog. And at 2, she it too young for a lot of the other things in the book.
It may be worth reading again in a year or two, and even then a lot of it won't apply.
This book is very readable.
