I've read that though birth is now a highly medicalized event in American culture, most modern midwives (most notably, the wonderful and deservedly famous Ina May Gaskin) believe that something like 98% of the time, women are perfectly capable of having a fully natural birth without interventions -- and I've heard almost exactly the same statistic from sheep farmers. The vast majority of sheep give birth to their lambs easily and without incident, only very occasionally needing a helping hand from the farmer. Inspiring, indeed!
Here's the birth video: it's not too bloody, but there's definitely some gooey things going on and it's no holds barred! I think it's amazing to see how easily baby number two just slipped right out. (Pardon the heavy breathing on the video -- I was excited, plus have been short of breath right from the beginning of this pregnancy!)
