I'm no
expert, but in addition to the vast amount of research I did before my 2nd child (homebirth), my experience with an ob before I switched to a midwife with that same child, my experience with a medicated vaginal
hospital birth w / my first child, my experience in
talking to dozens of women that have had surgical births, in addition to all that anecdotal «wisdom», I have taken a graduate level Sociology of Medicine class that was an in depth look at our current medical system from a sociological perspective and we spent a couple of weeks
talking about the medical model of birth and the alternatives.
