Mirabelle Heiser rifles through an assortment of crayons during arts and crafts time, Aug. 25, 2014, at the Aviano Co-op Care program at Aviano Air Base, Italy. Comparable to a convenience store’s “Take a penny, leave a penny” tray, the program asks parents to volunteer and accrue hours providing free childcare in a safe environment to earn credit toward childcare services for themselves.
