Query: Beautiful book- so important for any expectant mother to read!

I owe my entire natural childbirth and delivery to this book. I was calm, collected and centered. I never once had fear or uncertainty, because of the techniques I learned in this book. My labor was smooth, consistent and the baby was born less than 45 minutes after ARRIVING at the birthing center! I really enjoyed the techniques that it teaches you WHILE you're pregnant, to prepare for labor. The pain coping techniques, the breathing, the positions and stretches. I felt completely prepared for labor and delivery and it relieved any anxiety I had about pregnancy. I would buy this book for every pregnant mother I know!
