Fourteen is too young to be on a payroll, so most young teenage girls do baby sitting, help people with housework, or have a standing arrangement to shovel snow or do yard work. If she lives in a mild climate, having a morning paper route earns good money, although her parents may object to her being out alone so early. Households where both parents work always appreciate help with child care after school. If she can't commit to an every-afternoon arrangement, perhaps she could offer to take their children outside for some supervised active play for an hour once or twice a week. If she has a special talent such as sewing, photography, or music, she could offer an alteration and mending service, outdoor sessions taking candid photos of people's children, or music lessons for beginning players. Once she establishes a reputation for a good work ethic, she could print up cards or fliers about jobs she does. She still needs her parents' protection though. They should be acquainted with all of the people she works for, and know how to get in touch with her at all times.
