I read maybe 1/2 of this book pretty closely and then skimmed the rest. I'm bummed, because it's such an important topic--postpartum care is important and worth thinking about, and that's why it gets two stars instead of one.
The main thing that puts me off is that she gives a lot of specific medical advice, but the book's bibliography doesn't cite a single peer-reviewed source (except maybe one University of Chicago book published in 1960). I get that she is interested in alternatives to the medical establishment, but I was uneasy with how she was drawing from non-Western practices, too--I didn't feel I had any clarity about her method. The beginning of the end for me was a reference to a pretty famous John Gottman study about partners' relational satisfaction in the three years after having a baby. What she says: "Dr. John Gottman, a seminal researcher on parenting and relationships, found that on average there is a 67 percent decline in marital satisfaction in the first three years after having a baby." What the APA says in a report on the research: "After having a baby, 67 percent of couples see their marital satisfaction plummet, according to research presented at APA's 2011 Annual Convention by John Gottman, PhD, and published in the Journal of Family Psychology (Vol. 14, No. 1)." Those are very different things, and although the general point might be sort of similar, the sloppiness makes me worry about what might happen to me if I, for instance, followed her detailed exercise regimen.
Anyway, I had a hard time seeing most of the claims made in this book as credible, which is a shame, because, as many other reviewers have noted, if it were presented as more of a memoir with a collection of resources she's gathered, I think it would actually be more effective.
