What were baby's heart tones doing during those two hours of not pushing? What was baby's heart rate at birth?
Obviously, if the cord wasn't working at birth, it had just happened or you would have seen evidence of fetal distress in the heart tones. I wonder if it has more to do with the stress of "falling out" of mom than the calcified placenta?
I'm sure someone with more experience can answer more clearly, but IME, calcifications are usually associated with late (postdates) babies, unhealthy pregnancies (smoking), and poor diet (too much sugar).
