ooh ooh ooh! There is SO much good stuff out there!
When I was pregnant with DD, I read:
Ina May's Guide to Childbirh (LOVE Ina May). ((MY FAVORITE childbirth book))
The Thinking womens guide to birth, Henci Goer?
Pushed, Jennifer Block
The natural pregnancy book, Aviva JIll Romm
Birthing from within, Pam England
I also took Bradley Method childbirth classes, which were very helpful, esp to the hubby.
They have several books;
Natural childbirth the bradley way
After dd's birth, I watched the Business of Being Born, which was very inspiring. Def good to watch if you're interested in natural childbirth.
There are also tons of websites out there!
