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.
No surprise there. A recent study by Urbansitter reveled that with an average hourly rate of $15.34 for one child, hiring a babysitter costs you more in the Big Apple than it does in any other U.S. city. The survey of 7,500 families across the country reports the national average per hour for one child is $14.13. Other major cities cities, such as Chicago and Seattle, have rates around $11 or $12. The lowest rate of $10.84 can be found in Denver. According to the study, more than a quarter of parents hire a babysitter at least once a week and nearly 70 percent of those surveyed tip. Additionally, 47 percent said they spend more than $1,000 a year on baby sitting.
