This week's issue of Time magazine features a cover story on attachment parenting, a controversial form of child-rearing that involves breastfeeding to an older age, co-sleeping and wearing children in slings. It also features a cover image of a mother breastfeeding her three-year-old son that's sure to raise a few eyebrows.

The mother, Jamie Lynne Grumet, was one of three women shot by photographer Martin Schoeller who ascribe to the parenting philosophy. And according to Schoeller, the age of the children he photographed made for a nontraditional photo shoot.

“When you think of breastfeeding, you think of mothers holding their children, which was impossible with some of these older kids,” Schoeller said. “I liked the idea of having the kids standing up to underline the point that this was an uncommon situation.”
