We bought it. We used it. I regret it. This book is all about punishment, not discipline. There is a huge difference. If you want to have a close relationship with your child don't use this book or system. It does not encourage connection at all. I recommend Listen: Five Simple Tools to Meet Your Everyday Parenting Challenges. This book and system will work to get your child to behave, but at what cost? Is your relationship to them worth it? After a while, I could see that I was not addressing my daughter's emotional needs, I was just getting her to sit down and shut up. Like training a dog. People are not dogs. I am trying not to think about the damage I caused and I will try to be compassionate with myself because I did not know what I did not know, but I was searching through my past orders and came across this purchase from three years ago, thought about how much I regretted it, and decided to try to warn other parents away from it.
