It’s hard to ignore TIME’s May 21 cover. There’s Jamie Lynne Grumet, looking every bit the supermodel in superskinny jeans, ballet flats and a strappy tank top with the neckline tugged down to make way for … her nearly 4-year-old son. He’s breast-feeding. Over the past few months, breast-feeding has grabbed headlines as moms have staged nationwide nurse-ins to draw attention to their right to breast-feed in public. Mothers with babes in arms have collectively bared their breasts in Target stores; they’ve had their infants latch on at Facebook’s headquarters and at the state capitol in Georgia.

According to the CDC’s 2011 Breastfeeding Report Card, 75% of U.S. mothers start out nursing their babies, but only 44% have stuck with it by the time their child is 6 months old — and just 15% are breast-feeding exclusively by that point. By baby’s first birthday, less than a quarter of mothers are breast-feeding at all. From that small remainder emerges an even smaller group of extreme breast-feeders like Grumet.
