Nanny / Caretaker For 2 Children In Yonkers Near Tuckahoe [Car Needed]

We are looking for a Nanny for 2 children in Yonkers, located near the Tuckahoe train station. Ages are 5 (almost 6) and 2 (almost 3). We are looking for someone 2-3 days a week in the mid-afternoon / early evening, with potential for additional hours on an ad-hoc basis, and ability to stay a later on some of those 2-3 days if needed (with advance notice). While the 2-3 days per week will be the minimum, we are looking to build a long-term relationship with the person. We would prefer someone who has their own car in order to pick up kids from school and daycare. While both school and daycare are very much within walking distance, would need for inclement weather. We would prefer someone who could help out with light housekeeping, who does not smoke and who is CPR certified.
