Query: Essential reading for first time parents

This book was recommended to my wife and I by friends who had a colicky baby. They found it the only way to help their baby calm down (that and a trip to the doctor's to check to allergies, which you should do to rule out food allergies if you suspect colic).So far my wife and I have found the book useful and our infant does not seem to have colic. It is useful for getting the infant back to sleep from hour one of their life. The techniques worked wonders and the reasoning behind the techniques makes perfect sense to this layman. The techniques are also useful for calming your baby. For instance if you need to feed but the baby is too upset to take to the breast.All in all a life saver. Yes, your baby will still cry and sometimes not even the techniques here work, but 95% of the time you and your baby can have peace.I would get this book for anyone who is going to have a baby.
