How frightening that must have been! I'm happy to hear she did fine with treatment right away.
My babies were all section babies, so I can't compare them to vaginal birth babies. All four came out screaming their heads off. Only one was born after a few hours of pre-labor type contractions (SROM with contractions 3 minutes apart like clock work, but not particularly painful and absolutely no cervical changes whatsoever). The other three were delivered prior to labor.
Interestingly enough, the one born after a few hours of regular contractions was the only one who had even the slightest bit of concern with breathing. He was a bit 'grunty' at around 12 hours old, but nothing that warranted observation in the nursery or anything like that. It only lasted for a few minutes.
Statistically, he should have fared the best of the four babies since I'd gone into labor prior to surgery.
Statistically, my fourth baby should have done the worst since she was taken at 37w1d with no labor, but she was the most vocal of the bunch.
