Query: Skip this and get Ms. McCutcheon's book instead

Being the dutiful book-worm that I am, I thought I should go to the "source" to understand the Bradley method. I would say that only 10-20% of this book was useful. It is hopelessly outdated, despite being a "revised edition"; Bradley spends the majority of the time railing/advocating against "standard" birth practices (heavy use of anaesthesia, no dads in the delivery room, etc.) that may have been the norm when he first began developing his method, but are no longer. In short, he's preaching to the choir. I read the whole thing and promised I would pick out the salient parts for my husband...those parts would comprise maybe 10 pages. So, my advice is: skip this and get McCutcheon's book instead, which is more up to date and more practical.
