Occasional Nanny Needed For 2 Children In New York City.

We are looking for a great nanny for 2 children in New York on the days my husband needs to work double shifts. We would prefer a nanny who does not smoke, who is comfortable with pets and who is CPR certified. We would need the nanny from 9-5 for only a few days a month (or less), but often times to not have much notice in advance when the double shifts will be requested. Essentially we are looking for someone we can call to care for our children who would be open to caring for our kids on the sporadic days my husband is not home during the day to watch the children. We would give as much notice as possible before our request to care for the children, with the understanding they may not be available on the short notice we provide.
