Babysitting is the practice of temporarily caring for a child on behalf of the child's parents. In the United States, babysitting is commonly performed as an odd job by teenagers for extra money. Babysitting can be quite lucrative in some countries, but rates vary considerably according to the location. Babysitters typically work on Friday and Saturday nights when parents wish to go out. A babysitter is distinguished from a nanny by the term of employment.
Babysitters are normally contracted for one night at a time, while a nanny is employed over an extended period of time. In some countries various organizations produce courses for babysitters, mainly focusing on child safety and first aid appropriate for infants and children.
