While there are websites that act as aggregators for babysitting jobs, most are found through networking and referrals. Because few babysitting jobs are advertised, one of the best ways to find them is to spread word-of-mouth communication regarding one's availability as a babysitter.
Networking with friends and family is a good way to find babysitting jobs. Neighborhood families with children are likely to be happy to learn there is a nearby babysitter available. Friends who are babysitters often need to move on to more permanent jobs or school situations and can refer new babysitters to their clients. Babysitters who are already working can also ask their clients for new referrals.
