Dr. Kevin Leman has a phenomenal way of taking the difficult and problematic concepts of raising children, and making them simplistic and understandable. My wife and I have read and absorbed the things that he articulates in the book, and wonderfully, we would like to report that we have seen a dramatic change in our strong-willed five year old. Therefore, we in unison say, "It works!" Moreover, we recommend this book to any parent or guardian that is raising a challenging child. The principles are profound, yet practical, and will work - if you work them. Get the book!
