I just found nursing my baby extremely intimate. It's not something I could do for a stranger. I'd have no problem giving away the milk, but I don't think this was about nourishing this baby.
This was to make a statement.
There are a lot of hungry babies in the world, and donating formula(which she could afford to do) would be more helpful than breastfeeding one baby.
Formula requires access to clean water. Even ready to use products require access to stores (ie money & location) to purchase formula, bottles, nipples, etc. Even donated formula requires access to a distribution clinic. It is NOT a valid resource to address the issue in the areas of Africa that are most affected by maternal deaths and infant malnutrition.
FWIW, I know a bit about this. This September will be my 4th trip to East Africa to address orphan care issues, and it has impacted my immediate family as well.
My youngest son's almost died due to malnutrition after his first mother passed away. They were in rural Ethiopia a good 40km (a distance that he would have had to walk) from the nearest store in which his father could have purchased formula, much further from the nearest clinic or NGO aid station that might have donated it. The cost of one can of formula was more than he spent on feeding his other children for 2 weeks, and certainly out of his price range, before even adding in cost of bottles, etc. He was infrequently nursed by other women and Plumpy Nut was what eventually helped him overcome malnourished status but that was not recieved until after being placed in an orphanage. Solutions need to be found to help the child and family before it reaches the point where the family must relinquish the child to save his life.
Breastfeeding by others does saves MANY children's lives who do not have access to anything else. It is the best immediate solution for a child who is starving right then. If you have ever come face to face with a starving child, then yes if you can you are going to nurse that child. I cannot imagine not doing that.
It is far from a perfect solution however as breastfeeding is a known method of transferring the HIV virus, and the same areas which lack the funding or resources to provide formula or alternate feeding methods, lack testing for and education about HIV transmission.
IMHO, the best way to effectively treat this issue is to reduce the maternal death rate, by increasing the rate of girls who recieve an education. Girls who recieve an education are considered a resource to their family and are married an average of 4 years later. That additional 4 years in which the body is able to mature dramatically reduces the maternal death rate. In addition their education elevates their status in that they can obtain an income and statistically FAR more women then men who recieve education in these highly impacted areas use that education for the betterment of their local community (such as by starting medical clinics and teaching schools). Educated men are more likely to head to the urban areas, or apply for immigration out of the country. Unfortunately the male child is far more likely to recieve an education IF (and thats a big if) any of the children recieve an education at all. This however is a longterm solution, breastfeeding is immediate.
