Nanny For 3 Children, Part-time During School Year, Full-time In The Summer

We are a family of five and live in Ann Arbor. Given our busy work schedules, we need help with school pick up and after school activities for our three kids - ages 13, 9, 7. Hours are regularly between 2 p.m. and 6 p.m. T, W, Th. Should be willing to add additional days and times based on mutual needs. Will transition to full-time care over the summer. This is a long term opportunity (3 years at the minimum)
