I'll throw another vote in for The Pregnancy Book. All my pregnancy books are in storage (this pregnancy wasn't "planned" per se), and it's killing me! I took The Pregnancy Book out of the library and am loving it. (I also took out The Girlfriend's Guide, and cannot recommend that. At all.)
I also just read Skinny Bitch Bun in the Oven (a vegan book, fyi), just for fun, and it had some interesting info.
Looking forward to re-reading Adventures in Natural Childbirth by Janet Schwegel, Birthing from Within, Ina May's Guide to Childbirth... and oh man, there are countless others I have for my doula library. We move in a month, and I can't wait to crack that box open and oggle those beautiful books.
Non-baby related, I just read Jane Eyre again (love!) and A Homemade Life. Oh! And Consuming Kids, which was really good.
