This book tells you the things about birth interventions that your OB and childbirth class do not. It is certainly biased about a totally intervention-free delivery, but is honest and upfront about its biases. It is also good because it tells you how to avoid interventions, how to minimize them, and which ones to allow if you’re going to have one. I highly recommend this book to anyone who wants to even attempt a natural delivery. Note, Lamaze classes do not support natural childbirth (at least mine doesn’t).
