I cannot put this book down. Jones has three children of her own and uses her own experience as the jumping off point for exploring what it means to become a mother. She articulates and pulls together things which I felt but hadn't seen expressed so coherently anywhere else. The changes to our brains and bodies which happen through pregnancy and motherhood are so so fundamental in ways I feel like very few us knew about at all. I got flamed on here a few weeks ago for lamenting the loss of my pre-baby life - if I'd read this book I would have known that it's crazy to expect to remain the same person because we evolve almost into different types of people.
Where she's also good is in showing that our culture seems to see mothering as an individual job, when it's something which should be done within a much wider social group (and is in some other societies). This isolation is a big part of maternal mental health challenges.
(Completely wild that there is just one previous thread that even uses the word matrescence, on a site like this.)
