Lamaze and Mother's Advocate have a series of great videos available online on healthy birth practices here :

I really encourage women who are expecting to take a look at these videos. I found them both educational and empowering. Science and Sensibility is actually hosting a giveaway to get a DVD of these videos. If you are a doula or a childbirth educator, these can really help your clients, and since it's not always possible to have an internet connection where you teach, these DVDs could be really helpful.
