Dana Cheplin is the 8-year-old sitting charge of the Baby-sitters Club. She is the daughter of Mrs. Cheplin and the older sister of Adam Cheplin. Dana is a member of the Cheplin Family.


She was recently diagnosed with diabetes & uses a glucose test kit. Stacey suspects that Dana uses her diabetes to get her own way and make her friends guilty. When Dana's blood sugar level becomes dangerously low, Stacey takes her to Dr. Johanssen, who says that her insulin dosage probably needs to be adjusted.

She attends The Miller School with Adam and needs to be picked up from the bus stop at 3:15 p.m. sharp.

Dana's best friend is Mandy. She takes piano lessons and knows how to touch her nose with her tongue.
