Babysitters, or people hired to care for children while the parents are away, can be referred to by various other terms. Childminders and nannies are two commonly used alternatives to the traditional babysitter. While childminders generally look after children in their own homes, nannies are employed to look after children in the family home on a more regular basis. Au pairs, who are often foreigners living with a host family and providing childcare in exchange for room, board and pocket money, are another kind of babysitter. Teenagers who occasionally babysit for neighbors and family friends are sometimes referred to as Mother's Helpers.
