If you're having a natural, un-medicated birth, what happens after delivery? I hear about hospitals giving Oxytocin to help cause contractions to pass the placenta and that the doctor/nurse will massage/ press on your belly and massage it every 15 minutes for the first two hours after delivery. Do they have to do this? Doesn't the placenta pass from nursing, which causes contractions? And the uterious shrink on it's own? I don't know why, but I'm really weirded out by people scrunching on my stomach after delivery.
