Query: This book is dangerous

This book is full of the dangerous rantings of a perverted person. He actually recommends whipping children as young as 15 months of age and tells parents not to pick up their infants when they cry. The book is full of statements like these that are in direct opposition to any scientific research.As a parent who used a very different approach, I hope that people will keep away from this book and these methods. Yes, it is necessary to discipline children, but not by beating them. Children must learn to be self-disciplined, meaning it is important for children to understand the reasons behind rules, not just to behave out of fear.Stay away from this book if you love your children. Use these methods if you want your children to hate and fear you.
