If you have not yet been to EvidenceBasedBirth.com, get yourself over there! Rebecca Dekker, PhD, RN, APRN takes a look at the research on birth, and sums it all up in one convenient location. If you have a question about the evidence on something related to childbirth, she's probably got it over there, or she's working on it! I always go there first when I need high quality information for myself and my clients. Enjoy!
