In many families, the babycare role is taken on by the extended family. One of the challenges for parents who choose to use other sources of childcare is finding and affording qualified providers. Babysitting is the practice of temporarily caring for a child on behalf of the child's parents. Babysitting is most commonly performed as an odd job by teenagers for extra money, stereotypically, but not necessarily, girls. Babysitting can be quite lucrative in some countries, but rates vary considerably according to the location. Day care or child care is care of a child during the day by a person other than the child's parents or legal guardians, typically someone outside the child's immediate family. The service is known as child care in the United Kingdom and Australia and day care in North America. Baby care or day care is provided in nurseries or creches or by childminders caring for children in their own homes.
