There is a difference between a nanny and a babysitter. While both play a role in supervising and caring for children when parents are away, a nanny is a daily fixture. Nannies will provide housework and are very involved in the children’s lives.
Babysitters are short-term custodians of children who are typically hired to watch the children for a short, set period. Babysitters often stay with children while their parents go on a date, run errands, attend to emergencies etc or they meet the children after-school if the parent is unavailable.
