I saw this short (7 min) Birth Documentary on Mamas and Babies blog that has this excellent quote at the end:
"You are constructing your own reality with the choices you make...or don't make. If you really want a healthy pregnancy and joyful birth, and you truly understand that you are the one in control, then you must examine what you have or haven't done so far to create the outcome you want."
(Mother's Intention: How Belief Shapes Birth)
The documentary is pretty good too. I loved the nurses' candid explanations of the common medical procedures done during labor. I wish I could open the eyes of all women to the idea that they don't have to be a passive spectator in the births of their own babies. There is such a better way.
