Nanny Needed For My Children - Full-time / Part-time

We are looking for a great babysitter for an 1 1 y/o child in Arlington. The responsibility largely involves driving our daughter from school to activities and bringing her food for the transit. She is very easy. We would prefer a babysitter who has their own car, who does not smoke and who has college degree. Hours are typically some variation of 3:30 pick up from school through 6 or 8 p.m. with less time necessary on Fridays.
