There is an excellent article in the New York Times on the pressure to breastfeed.
"All too often, breast-feeding advocacy crosses the line from supporting a woman in her decision to breast-feed into compelling a woman to breast-feed. If breast-feeding is the measure of our moral worth, it isn’t long before the idea of a mother not breast-feeding her child summons the familiar tropes of bad parenting and irresponsible citizenship that we have long deployed against poor women and minorities."
