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

We are looking for a great nanny for our preschool age son. Able to be flexible about exact hours and schedule. We would ideally like someone who is both patient and energetic. We would prefer a nanny who has their own car, who does not smoke, and who is CPR certified. There is one cat in the home. We do not expect any housekeeping or pet care, just someone to spend time with our sweet and active child.
