Nanny Needed For My Children

We are looking for a babysitter for our 1. 5 yo son. This would be a position that would vary each week/month. It would be anywhere from 2 to 8 hours for either when I have an appointment or need to go into the office as I work from home. We would prefer someone who could help out with light snack/meal prep and housekeeping. We would prefer someone who has their own car, who is comfortable with pets (we have 3 cats and a dog), who is CPR certified and non-smoker.
