Aiden Kettelhut, 3, of Durham concentrates as he navigates through a game of “Caillou” at the Auburn Public Library’s computer lab on Friday. Aiden was spending time with his older brother, Ehric, and his mother, Valerie Kettelhut, who are part of a home-schooling group and make regular visits to the library. Kettlehut said this a great place for the children; it gives them an opportunity to play, socialize and check out books.
