Volunteer Luis Granja uses a doll to practice swaddling an infant while fellow volunteers, Gertie Rogers, background left, and Kathleen Jones, background right, watch at the University of Chicago's Comer Children's Hospital in Chicago on Wednesday, Feb. 19, 2014. About 20 people attended an orientation for volunteers who cuddle babies in the neonatal intensive care unit. Research shows that cuddling helps calm the babies, many who are born prematurely or who have serious health issues, and aids in their early development. (AP Photo/Martha Irvine) less
