I have begun using Dr Lehman's concepts on my granddaughter and am already noticing a change. Just getting started, but so far id say it works and anyone with kids - especially these days- should give it a try.
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!
Not finished reading this yet, but just after applying the principles from the first chapter or two, I am seeing results. Less stress in the home, a more level head, enjoying each other more instead of feeling like a dictator with a yelling problem. Thank you so much for giving us guidance in parenting. You could also call this book, Parenting for Dummies, it really would be great if your children came with instructions :)
