Part Time Nanny Needed .

I am looking for a reliable, long term nanny for my kids for Mondays and Tuesdays, 7:30 am-4:30 p.m. (or later). Additional days/hours can be available. We have 3 kids, aged 2, almost 4, and 8 and live uptown. Our 8-year-old is in school full time, but may be off from school on occasion - she is pretty independent and self sufficient. Primarily care is needed for the 2-year-old and the 4-year-old. Our 4-year-old is in preschool 9am-12 p.m. every day, but occasionally school is closed. Additionally our 2-year-old will be starting at the same preschool this summer as well. As such, I would like someone to be able to drive them to school and pick them up, so a reliable car and a clean driving record is a must. While the kids are in school or napping (they currently nap every day, around 1-3 pm) I would like help with some light house chores.
