A mother arrived around 5:30 p.m. Tuesday to pick up her son, but he couldn't immediately be located. He was found napping under a tree.
YWCA executive director Glenda Mathis says the boy appeared sluggish, but wasn't harmed. His mother took him to a hospital to be checked for possible dehydration.
Mathis says the two staffers failed to do a mandatory head count as about 15 campers, ages 5 to 12, were moved from a playground to a gymnasium.
The forgotten boy's name and age weren't released.
