The people who give glowing reviews of this book remind me so much of my mother. She was so happy about how well spanking worked and she really believed it was a good thing. The problem is that the negative effects are shoved underground and are likely not to emerge until teenage-hood or adulthood. When you teach someone that deliberate physical pain is a healthy way to control unwanted behavior you to teach them to use violence on others and on themselves.When the goal of parenting is breaking a child's will there aren't the ordinary safeguards in place. Children have died because of this book's teachings.
