You say you wonder why people decide natural is best?
I can only speak for myself but I have had an em cs, under GA and an el cs under local. I hated both experiences, my el cs wasn't too bad and I had no problems with recovery but to me it didn't seem right.
The major worry with vaginal birth I find is the pain, this is not any less after a cs, the pain is there, just in a different place and at a different time, at least with a vaginal birth that has gone well you can get pretty much up and about straight away, not so with a cs.
Problems such as the cord being round babies neck are normally easily resolved by the midwife delivering you. As for loss of control, I have never felt less in control than when I was unable to move in an operating theatre!
Also having a cs transfers risk to any latter babies you may have, the risk of uterine rupture increases as do other things.
Like I said, I can only speak for myself. Hopefully someone who knows more facts will be able to come along and help you.
