The latest issue of TIME Magazine shows mother Jamie Lynne Grumet breastfeeding her nearly 4-year-old child. Breastfeeding at this age is uncommon but a growing number of parents are engaging in the practice for a number of reasons which TIME goes into. The nationwide cover has caused some controversy namely because of the photographic content which many readers may not be accustomed to.

The photographs were taken by Martin Schoeller and My Modern Met has more images from the issue which show four other families engaging in prolonged breastfeeding for their children.
