I can also recommend 'Ina May Gaskin's Guide to Childbirth' as well as Shiela Kitzinger's 'Birth Your Way'. Both of these books really helped me learn a lot about the mechanics of birth, and how to prepare my mind and body the best way possible. I also really enjoyed watching the film 'Orgasmic Birth' (strange title, great film). 'Birth Your Way' has a list of questions to ask a potential midwife that you might be interviewing.

My best advice is to meet a few midwives and find one who makes you feel very comfortable, both in their approach to your medical care, and also in the way you relate to that person. It is important to find someone who can nurture you through the process of your pregnancy, labour, birth and afterwards.

Best of luck! And enjoy!
