I'm not currently pregnant, but I have two kids and I am a doula (I assist mother's while they are birthing, and help them out before and after the delivery as well). I am also a La Leche (breastfeeding) coach. Feel free to email me if you have any questions or want to chat about birthing and babies -- they're my favorite topic!
A book that I recommend is "Natural Childbirth the Bradley Way". Even if you are planning to use drugs during your labor, this book is really great for learning some techniques that will get you through the portion of labor before you can have an epidural (lots of moms don't realize that this can be a looonng portion of labor). The Pam Englund book is also great - she's here in Albuquerque where I live and has an awesome doula program.
For after the delivery, I suggest "Your Baby and Child from Birth to Age Five" by Penelope Leach. (I just looked at at Amazon.com and they have some copies for $1.75!) I wore my copy out when my kids were little!
