Part-time Nanny Needed For 3 Children.

Looking for a mature (grandmothers welcome!), experienced part-time nanny for 3 children: twin 11-year-old boys and a 14-year-old. would prefer someone who could help out with light housekeeping. Main need is pick-up of children (around 3 pm) in Riverdale in the Bronx. Then driving to various activities. Would prefer someone with her/his own car and a clean driving record. Some light housekeeping, grocery shopping, and cooking might be requested, time allowing. We have a very gentle Labrador Retriever.
