Can i just as, if you live outside London, and look after pre-school children, what is the typical mileage for a nanny? Ours is creeping up, I'm certain she is doing the miles, and there are more car journeys then in summer as its so cold. But there seems to be a lot of trips she doesn't really need to do, and it feels like she's supplementing her income with mileage. Is is unreasonable to ask her not to take DD to the next town (17 miles round trip - ish) more than once a month, we live a big town where there is everthing you need. She's done in 3 times in the last 2 1/2 weeks so it's starting to add up
