Elena tipped me off to this opportunity, and she has already written a fantastic post explaining how it all works. Basically, if you're a healthy nursing mom, you have the opportunity to pump extra milk for other babies in need. Some of your milk goes straight to Africa, to feed HIV babies. The rest is used to help NICU babies here in the States.
A few weeks ago a friend of mine was in the hospital for a few days and wasn't able to breastfeed her 10 month old. To help out, I pumped extra milk for her daughter. I was amazed at how easy it was to feed a second child (albeit not entirely!) and how quickly my body responded to the increased demand.
Maybe you don't have much money and can't support aid organizations in the usual manner. This is a way you could give. All it takes is a little extra time - the organization supplies the pump, the shipping supplies, and pays all shipping and processing costs.
There is something beautiful about being able to give, quite literally, of yourself to others. I would encourage any of my readers who are breastfeeding now or in the future to consider giving in this way.
