I would suppose if the baby was 'cooked', vaginal birth would be the safer way to do things (better for baby's lungs, and the fact that C-sections are major abdominal surgery, with all THOSE risks). The problem is, they get it wrong a lot.

When I was pregnant with mr_t00by, I had FOUR u/s and an amniocentesis (to determine 'lung maturity'). The amnio was what sent me into labour (which isn't uncommon). It was three days past my due date, so I wasn't worried. The results came back (after he'd already been born)that his lungs weren't ready, which was entirely false because he was breathing just fine and there were no respiratory complications. In this case he was 'cooked'(all 9 lbs. 9 oz. of him) despite the test results.

The problem with working against nature like that is that nature is usually way smarter than science. IMO, messing with mother nature is a tricky thing.
