Did I read that she is a prem mum too? Perhaps she is upset with her body for not growing her bub to term and whatever other issues there were going on with the pregnancy. So to make herself feel better about everything that went wrong, she is focusing on the thing that went 'right' - giving birth vaginally. Maybe it is a case of blowing out your candle to make hers shine brighter?

Or she is just a stupid B. Of course a C-section is a birth, otherwise you would have a child that was never born.
