Query: A horrible book

This author shows no understanding of strong willed children (or any child for that matter). This book gives the exact wrong advice for dealing with our wonderful, gifted, and strong willed children. A wonderful reference for those who want to have a loving relationship with their strong willed children is Raising Your Spirited Child by Mary Sheedy Kurcinka. Dobson's book is just one more piece of trash to be thrown away.
