For supporters of physiological childbirth

I have found in this book answers to my questions about the pain of childbirth without an epidural.
By cons I do not really like the side a bit "new age" of certain passages. I'm not necessarily partisan "all organic" (a épisio it's still better than a tear in my opinion) but this book reinforces my belief that modern medicine frankly deprives the wife of his birth. I give birth soon and thanks to this book I do not intend to let me impose acts that seem unnecessary.
One last point: there is some evidence that is still not super reassuring on the pain of childbirth! :)
