The birth story of Rosalind Yates Reed is great. It was a natural birth, and for a while there it sounds like it was a real pain in the ass, dragging on and on. But the point is that they got through it by trying a whole lot of different things, and they didn't go for any of the standard hospital interventions.
I'm having trouble expressing why this story made such an impression on me. I guess it's because the labour was long and hard, but they stuck to their principles and kept trying lots of different things to move the labour along. So often I get the message that you can only have a natural birth if your labour is easy and progresses well.
