I'm booked in for an elective because of a massive fear of childbirth. Whilst no one has encouraged me to do so, the hospital has been supportive and respectful of my decision.
It should be your decision, and that decision should be respected, that's what the guidelines say. If you need to stamp your feet a bit to make sure, then do it.
And yes, a textbook natural birth might be 'better', but it's not a choice between a planned section and that.
It's a choice between a planned section and the roulette that is natural childbirth. As a woman in my mid 30s having her first baby, my chance of having a birth that isn't section or instruments is about a third. Add to that the number of non assisted births first time, which have significant tearing etc, and you're looking at the likelihood of a significant recovery either way.
Also, whilst sections cost more initially, in time they cost about the same as a vaginal birth once you factor in repair work, physio etc, so don't feel guilty about taking up extra resources.
I've had friends who have had an elective that were home the next day, and found the recovery easy, staying in less and recovering quicker than those I know who had vaginal births. Some the other way round. There are no guarantees, but your choice is perfectly valid.
