Though many charges in the so-called “mommy wars” are trumped up, there’s one issue within them that is demonstrably fraught: breast-feeding. Formula-feeding women are told that “breast-feeding is optimal” and that they do their babies a disservice by not nursing. Some American hospitals are so pro-nursing that their entreaties to breast-feed make new moms feel uncomfortable. The latest flashpoint in the breast-feeding wars is about whether or not women with surplus supply should be selling their breast milk or whether they should only be giving it away altruistically. What undergirds this particular strain of controversy—and pretty much all of breast-feeding-related controversies—is the notion that breast milk is so far superior to formula that it’s an unparalleled, precious, nearly magical commodity.
