Here is an interesting article about the difference between animal birth and human birth. Very well written, and with a good point, though not so biased as some articles are. Safer in a barn.
Happy Birthing!
What is the difference?

My name is Samantha Mehaffey, I'm a wife and a mother of four. My husband served in the Military for 8 years and during that time I birthed two of my five children and served a few people as a volunteer doula, now he is working in the civilian world and we've added a third and fourth and fifth child (all born at home) and I've increased my business and gotten certified through DONA, and now I’m working toward becoming a midwife. I LOVE this job almost as much as I love raising my children. Bringing babies into the world through prayer and helpful relaxation techniques is the best feeling in the world!
