Query: New way to calm frustrated parents!

This book is a life saver for any parent. I don't care if you're first timers or seasoned veterans, this book is a must! I've recommeded it to every one I know; new parents, grandparents, and parents-to-be. It will be my signature shower gift for the rest of my life. Moms, if you have a husband that wouldn't read a baby book to save his life, get the DVD, it teaches the basics in 20-30 minutes and you won't have to beg!At first you think Dr. Karp is a miracle worker, but after reading the book, everything just makes sense. It's changed my whole understanding of babies. I hope that more people buy this book so there are happy babies and parents all over the world. Thank you Dr. Karp!
