Hmm, I guess the reason for the caesarean would probably influence whether this was allowable. EG if it's deemed unsafe for you to labour or attempt a vaginal birth (like with placenta praevia, or if you have a previous vertical caesarean incision for example) they definately wouldnt want to allow you to go into labour. But if labour is seen to be a fairly safe option, then I guess they would be more open to the idea. I guess you never can tell how long or short a labour will be and how long it takes to get you into theatre IYKWIM.
