I think it all depends on the circumstances. My natural birth almost killed me and my son, so a c-section was a walk in the park in comparison. Ella, sounds like you had a rough time last time too.
That's a different way of looking at it, I guess. I've actually opted for the planned section because I don't want to run the risk of putting my baby through distress like my first baby went through - added to the fact that I'll be hooked up to goodness knows what because of my previous pre-eclampsia and now the diabetes, so won't be able to move around (not particularly conducive to labour.
It was a tough choice though and has taken me pretty much my whole pregnancy to come to that decision.
