I had a c/section. I feel it was totally unnecessary. I don't wanna recap the whole thing, but my birth story is posted under the Birth Stories forum if you feel like reading it. Basically, my baby and I went through many many interventions to the point where nothing about my labor was natural. I was scared into a cesarean.
I have to respectfully disagree with you when you say it isn't helpful for women to label their cesareans as necessary or not. Some women, including me, had extremely traumatic births and have a lot of processing to do. A lot of healing to do. I had Post traumatic stress disorder after my labor/cesarean. In sorting through what happened, it was important to me to be fully aware of the lasting implications of what I was told.
Did I actually believe that my pelvis was too small? That my baby would have gone into distress if I hadn't had the c/section? Did I believe that I couldn't birth naturally? These questions were EXTREMELY important to me, because I wanted another baby. If I believed these things, I would probably now be planning a repeat c/section. But I don't believe them. Hence, I feel my c/section was unnecessary, because I feel all the "reasons" for me having one were based on false conclusions, IMO.
So figuring out my c/section was unnecessary was important both to my emotional healing, and my planning of my next birth.
Needless to say, I am planning a VBAC. A home water VBAC.
