I ended up doing a 1 month internship with Mercy In Action in The Philippines last spring. It was an incredible experience that solidified my desire to work as a volunteer midwife in developing nations. If you'd like to hear more about my experiences, I'd be happy to share with you :)
Presenlty, I've just applied to The National Midwifery Institute and I've been researching where to go next... possibly Haiti, Mexico, or Africa.. if you're interested in finding volunteer opportunities, maybe these links will help you in your search:
"Above all, I wanted to implant the secret of love in your hearts. I hoped to teach you to be brothers to all living things, and to become so full of love that you will not fear even sorrow and death and receive them like brothers and sisters as they come to you."
