For teens who enjoy working with younger children, babysitting is just one income-producing opportunity. Work for a recreation or community center as a camp counselor or game coordinator. Coach recreational sports programs for children, or serve as a sports referee, scorekeeper or umpire. Older teens may work as full-time nannies during summer months. Responsibilities include caring for children, transporting children to and from lessons and events, and occasionally pulling overnight babysitting shifts.
