I recently finished reading and reviewing a great new midwifery memoir, The Blue Cotton Gown by Patsy Harman. This book was written by a CNM who no longer attends births, so it was about the rest of midwifery--the well woman care side. It was very good.
A few months ago, I also read the very excellent Lady's Hands, Lion's Heart, another midwifery memoir (this one had lots of births and also lots of drama!). I really loved it. Very good.
In short order, I also read Labor of Love, by the CNM who was shadowed in the film The Business of Being Born.
If you get the opportunity to read any of these books, I think you'll enjoy them!
