Query: Best Self-Help Book on Understanding Babies

I came across the book when I was pregnant. All I can say is, I have read many books on child care and when my baby was born, I pretty much toss out all the books I read except for this one. I would not know how I would survive if I did not know Dr. Karp's techniques. For all new mothers out there, this book is a godsend. Thanks, Dr. Karp!
