Nanny For 6 Month Old Boy (24-28 Hours/week)

We are looking for a nanny who is extremely comfortable and experienced with infants (our son will be approx. 6 months old in March). We need someone who is CPR certified, experienced, and able to help us 6-7 hours per day/3-4 days per week (mostly Monday-Thursday 9am-3pm). We need a nanny who has their own car, who does not smoke, who is comfortable with pets, and who is able to clean up messes made with the baby throughout the day. We are also looking for someone willing to do light housekeeping when the baby naps. At least one of us will be in the home when these services are needed (we primarily work from home). So we are available in an emergency or to help when needed.
