I have been thinking of having a natural childbirth or at least attempting it and people keep telling how important it is to be physically fit. Granted, I am no where close to being as physically fit as I was prior to becoming pregnant, but is this really a dealbreaker? I just hate for people to keep tellling me that I might not be cut out for it. It's probably too late in my pregnancy to take any addtional natural birth classes(Bradley, etc), but I really want to see how far I can progress in labor before I even consider the thought of medicine. Thoughts?
