After one week Nanny requested more money, is this common?

My wife and I moved across country and both started new jobs. We hired a nanny and she started last week. Prior to her starting we went over her salary in detail, specifically how much she would get at the end of each week.After the first week, we were told that after calculating her bills, she needs an increase in salary.Is this common amongst nannys or is our nanny attempting to take advantage of the fact that we both started new jobs and can't take off from work in a city we know virtually no one? via /r/Parenting http://ift.tt/2aktGHz
