There are two ways in which online babysitting services work. With the first method, parents post a job and then the sitters who are interested and nearby contact them. This may be done via email or telephone. The parents can then respond accordingly. With the other method, parents can look at the profiles of potential babysitters and then contact the best ones. When searching, you get immediate access to babysitters. Simply type in your zip code and a list of local sitters pops up. When you click on a sitter, you may get a brief bit of information or their entire profile.
