Just wondering, if your baby came out facing posterior, how badly (if any) did you tear?
I'm pretty sure my baby (first vaginal birth) came out posterior, though no one actually saw her come out, so I'm not sure, but she was facing that way until I was 10 cm and I only pushed for a few minutes, on my hands and knees. She had a slightly bigger than average head, and weighed 9lbs 6oz. I had quite a bad 2nd degree tear. Unfortunately, against my instinct, the only time I actively pushed was when she was crowning, and I felt a big "pop" then when her head came out and I tore. I really wish I had slowed down then and not pushed, as my greatest birth fear was tearing, and I still feel sore 7 weeks later.
But would it have made a difference if I had not pushed actively? Do most posterior babies end up with tearing anyway, especially when they are big and first baby?
