Hi, I understand your situation. I’m a
live-in nanny in Dubai and I drive the kids every day for school drop and pick-up and also take them to the park. I think you can ask in a simple and polite way, like saying that since you sometimes use your car to take the kids to activities, you wanted to check if fuel reimbursement and maybe some support for car cleaning can be arranged. It’s a reasonable request because driving even once a week still costs fuel and the car gets messy with kids, and most families will understand if you explain it nicely.
