Query: Saved my life!!!

This book saved my husband and I! The first night home with our son he cried all night long! Around midnight I could not handle it any more. I had bought this book before the baby was born but hadn't read it yet. I sat down and read the book. At 4 am my baby was still crying with my husband and my husband was at his wits end. I used the 5S's that were explained in the book. Within 20 minutes my son was out like a light. (And so was my husband) We used this method and my son did not have anymore crying fits like that again. He is now 19 months and I have just purchased Dr. Karps The Happiest Toddler. I can't wait to see how it works! Thank you Dr. Karp!
