My mom had four, and I'm pretty sure she said that only the last one produced vaginal tearing -- and this includes the next-to-last, who was ten pounds, eight ounces and had elbow presentation, as in wrapped-over-his-head. (That one, she swears that if she'd been doped to the gills as was tradition in the hospitals in that era and area, she'd not have been coherent enough to decide to live. The attending doctor did not like what her blood pressure was doing there for a while, though.)

But the last one, she said the contractions were so hard and fast that she didn't have a long, drawn-out pushing, so... tearing.
