Nanny Needed For My Children

We are looking for a great babysitter for my children in Pleasanton. I work per diem as an RN in 12 hr shifts and we need occasional al coverage. I have four kids ages 6-1 yr. Grandparents could also help sporadically through the day because we realize 4 is a lot. We provide a car to drive if needed while caring for kids. We would prefer a babysitter who does not smoke, who is comfortable with pets and who is CPR certified.
