Seems to me that if you can afford to keep your Nanny around, and you and the girls like her, keep her! Even kids who are in school seem to spend large amounts of time home sick with various germs. Maybe you could trade one of your evening chores to the Nanny while you do an hour of homeschooling after work?

Just a thought,
