The Pregnancy Book A great month by month resource, much better than the "What to Expect" series.

Gentle Birth Choices: This book helped me to decide on the kind of birth that I wanted to have.

The Continuum Concept The most important book I read as a parent-to-be. "the continuum concept is the idea that in order to achieve optimal physical, mental and emotional development, human beings — especially babies — require the kind of experience to which our species adapted during the long process of our evolution."

Our Babies, Ourselves: How Biology and Culture Shape the Way We Parent -a wonderful cross-cultural comparison of child-raising practices, from feeding to sleeping and everything in between. A wonderful book to read along with The Continuum Concept, providing more data and information to back up the assertations there.

Questioning Circumcision : A Jewish Perspective We made a decision not to circumcise our baby. For us, the medical decision was really clear - what was hard was the religious, cultural & family implications, against the obvious harm and pain done to a non-consenting child. This was a book that helped clarify our thinking, and gave us good material for discussions with our families.

The Womanly Art of Breastfeeding - If you're having a baby, you should plan to breastfeed (barring major medical complications, of course). Moms planning to breastfeed should find a La Leche League meeting near you to go to before and after your baby is born, and get this book for the best of the best of their advice. Unless you've seen someone nurse up close and personal, you should go to a meeting even if you get the book - positioning is everything, and it's hard to learn from pictures.

Natural Family Living: By the editor of Mothering magazine (which I also highly recommend!)

The Vaccine Guide: Making an Informed Choice - Let me be clear - as far as I am concerned there are NO good resources out there that present information about vaccines in an unbiased and rational way. That said, this book has some helpful information in it and it's been a help in choosing what vaccinations we felt were appropriate for Zach to get, which ones to delay, which ones to skip.
Natural Family Living also has a good chapter on vaccination.

The Baby Book: Everything You Need to Know About Your Baby from Birth to Age Two - By the authores of The Pregnancy Book above, this is a great resource book. Sears coined the term "Attachment Parenting" and goes into detail on what it means and why you should do it in this book.

Smart Medicine for a Healthier Child - this is a great resource to have on hand. It talks about all of the common childhood ailments, and gives allopathic (normal western medicine) remedies, homeopathic remedies, herbal and nutrrtional remedies, and then makes a recommendation on which are the best to use in a given case. The only book I've found that does this sort of comparison - I bought the grown-up version as well.
