Nanny Needed For 2 Children In Watertown

We are looking for a great nanny for 2 children in Watertown. Nanny would be home most of the day with our 2-year-old. We would love someone who can take her to the park and local library. No screen-time please. We would need nanny to pick up our oldest, 4-year-old, in the afternoon from a local preschool. We would prefer a nanny who has their own car, who does not smoke, who is comfortable with pets, who is CPR certified and who has college degree. Looking for someone available from 8 a.m. to 5 p.m. Thank you.
