The area that is now New Mexico became part of Mexico after the  Mexican War of Independence in 1821. It was ceded to the United  States in 1848 after the Mexican-American Wâ¦ar and the Treaty of  Guadalupe Hidalgo.
Unlike nannies, babysitters often work part-time or on an âas-neededâ basis for several families at a time, and are paid hourly at the end of a shift. Hourly rates are influenced by cost of living and minimum wage laws. According to a 2017 survey of Sittercity babysitters, the U.S. national average is $13.95/hour.
The overall average hourly cost for babysitters in all cities is $12.75. Other sites, like Sittercity.com and Care.com, offer alternative (and seemingly more modest) rate calculators. Care.com recommends $12.50 per hour for a single-child sitter in New York City; Sittercity.com recommends $14.50.
