Haylee Carroll plays with her nearly one year-old daughter, Eris, Friday, March 28, 2014, in Oliver Springs, Tenn. Elis has rare genetic disorder — Cockayne syndrome — that she shares with her late brother and sister, and with 300-500 living children worldwide. Carroll is an organizer of the Butterfly Walk to raise awareness of Cockayne and money for research about the disorder which causes extreme premature aging in children.
