For women with oversupplies of breast milk, or those who have been banking overwhelming amounts of milk in their freezers, it is not advised that you take out an ad to sell it, as a woman in Iowa recently did. She offered 100 ounces of frozen breast milk for $200 because her 4-month-old daughter won't take a bottle and she has built up a large supply of milk in her freezer.
The Human Milk Banking Association of North America has very specific guidelines for donating milk, including going through a lengthy screening process. If you are interested in donating your milk, it is suggested that you familiarize yourself with the details of a milk banking program (there are 11 banks in the United States), so that neither your milk nor your time is wasted. The woman in Iowa is now donating to the Mother's Milk Bank of Iowa, but unfortunately the milk that she had advertised was not eligible for donation because it was pumped before it was screened.
