Hi princessz, I can understand your worry about VB, the pain trauma etc, but a CS is much more traumatic for your body. As someone pointed out earlier, your body is meant to go through labour and VB, having major surgery (and that is what it is) puts your heart/lungs etc under much more stress and shock. I really would think long and hard about it before you make a decision.
I am desperately trying to avoid a CS (for medical reasons), and really want a VB, and if I keep doing as well as I am currently, then I should be able to have one :) But if not, I'll have to spend the first 24hours in ITU, and not be with my baby at all (though DH gets to stay in hospital with her for that time), which scares me more than anything. I can't stand the thought of being separated from my LO for that length of time before I've even gotten to know her.
I was chatting to one of the prev-antenatal ladies yesterday, who had her baby 10wks ago. She was saying that with hindsight she wishes she could go through labour again and appreciate it, as it was not as bad as she thought, and knowing that things were going to be fine at the end. It made quite a few of us 1st timers feel a bit more confident.
If you want a relatively pain free labour perhaps you could opt of an epidural? They relax your lungs and heart. Also, have you though of doing more antenatal classes like yoga or hypnobirthing? I've been doing yoga and it really helps with concentration, learning positions for pain relief and breathing exercises - and the MW was saying that those who did antenatal yoga generally had quicker and less traumatic labours and births. I'm not saying it'll be a walk in the park, but there is help out there to make VB easier to cope with.
PS Caesarean is meant to relate to the method from which Julius Caesar was born (there is some quote about him being born in an unnatural fashion), although it is likely to be tosh as his mother would not have survived that sort of op in Rome BC, and she was definitely around during his childhood :o
