In 20 U.S. cities, finding one of the most important tools in a parent’s arsenal – a good babysitter – just got a little easier. Entrepreneur Mary Sullivan Cooper has been playing matchmaker for several years with her service, MommyMixers, which arranges for moms to meet prospective babysitters. “Welcome to the MommyMixer [1],” the Austin American-Statesman [2] proclaimed, “which brings sanity-strapped moms together with cash-strapped college students and aims to make matches that benefit both. Moms register well in advance for the events, which almost always sell out.” The paper quoted a mom who hired several babysitters through Mixers as saying, “It’s a mutually beneficial relationship – we get smart, responsible and energetic nannies and they get a fun job in a safe environment that helps them with expenses while they are in school.” (September 2007)
