Part Time Nanny Needed for my Children

We are looking for a nanny for 1 child (6 months) in New York (Hells Kitchen neigjborhood near many subways). We would prefer a nanny who does not smoke, who is comfortable with pets and who is CPR certified. Essentially seeking someone to assist with watching/playing with our son for a few hours and assisting with 1 to 2 naps. Either parents will generally be present, but working, and/or running errands.
