Yes, do read books about pregnancy and childbirth...but do also expand your bookshelf to include books on baby care, discipline strategies, parenting, etc. Once the baby arrives, you will probably be hungry for the information, but you may not have the pleasure of sitting down on the couch to read a book.
Here are a few book titles to get you started. Anyone else have suggestions?
* Easy Labor: Every Woman's Guide to Choosing Less Pain...by William Camann and Kathryn Alexander
* Born in the USA: How a Broken Maternity System Must Be Fixed...by Marsden Wagner
* What to Expect When You're Expecting by Murkoff, Eisenberg, and Hathaway
* The Baby Book by William and Martha Sears
