Query: DO NOT WASTE YOUR MONEY!

This book is a waste of time and money. It is written in large type with a lot of empty space on the pages. I was hoping to learn new parenting strategies to use with my 20-month old son, and didn't read anything that I hadn't heard before. The bottom line is that there is really no substance to this book at all. Each chapter is literally 1-2 pages long.
