An afternoon with a Princess

Today I'm a stand-in-mum, doing the nursery run followed by after-nursery activities and dinner at five. How does everybody do this? Working full time clearly doesn't allow for picking up anyone at three in the afternoon, let alone after-nursery activities. You have to work part time, or have a well paid job where you can afford for somebody else to fill in between three and six. Unless you want your offspring to stay at nursery until five thirty and skip any kind of extracurricular activities, which seems unthinkable as s/he would be the only one.

The equation is somehow missing one or two variables.
