Margulis, who has already distinguished herself by peddling appalling misinformation about vaccination now turns her attention to birth. Even the blurb is filled with misinformation. Margulis apparently does not know that infant mortality is a measure of pediatric care, not obstetric care. According to the World Health Organization, the best measure of obstetric care is perinatal mortality and the US has one of the lowest rates in the world, thoroughly undercutting the central claim of this book.
Margulis' book has nothing to do with science and nothing to do with journalism. It is a full throated lobbying effort on behalf of the natural childbirth industry, including midwives, doulas, childbirth educators, and lobbying organizations like Lamaze and the Childbirth Connection who make all their money from scaring women about modern obstetrics. Margulis quotes only a non-representative fraction of medical professionals who are own record as supporting the same causes that she espouses.
The people in the US who are most educated about childbirth are female obtetricians who have more professional and personal experience with childbirth than anyone else. They have no patience for conspiracies, smears and misinformation broadcast by lay people like Margulis. This is a book written by a lay person to transmit mistruths, half truths and outright nonsense to other lay people. If you are interested in scientifically accurate information about childbirth, you should look elsewhere.
