Many people are vaguely aware that "too many cesareans are being done," but they are unaware of the cause-and-effect that lead to preventable cesareans and other interventions. I know this because almost every woman who has had a cesarean, thinks that *her* cesarean was necessary/life-saving/not preventable. Statistically, over half a million preventable cesareans are performed annually in the US, so SOMEBODY'S cesarean was preventable.
(Contented sigh as I revel in reading the thoughts of others that validate my own. Someone else said it. I can't be that crazy. :)
