Stories like Little Red Riding Hood and Hansel and Gretel might be fantasy, but in the days when wolves and outlaws patrolled the forest, they were a warning for children to keep out of the woods.
Researchers from Wake Forest University and the University of North Carolina studied 30 children diagnosed with nutritional rickets over a 10-year period.
That led to color-coded paths, a Magic Forest in the main lobby and a wishing tree where family members can write their hopes for hospitalized children.
