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.
In 2009, the average baby sitter was paid $10.50 per hour; in 2014 it was $13.44. But if you have more than one kid, expect to pay up to $5 per hour more for each additional child.
