Babysitting isn't just for middle and high schoolers. If your end goal is to work with children after college, reaching out to families near your campus that need child care can be a lucrative move. Working parents often need someone to supervise their young children after school until they get home from work, so if it fits your class schedule, you could probably get a steady weekday gig. Otherwise, consider sacrificing a few weekend parties in favor of kids' movies and board games to earn that extra cash.
