Babysitter Needed for my Children

We are looking for a great nanny for 2 children in Saint Louis. One is a 2. 5-year-old boy who attends daycare (will only need help in the afternoon) and one will be a newborn coming in Oct that requires all day care. We would prefer someone who could help out with light housekeeping. We would prefer a nanny who has their own car, who does not smoke and who is comfortable with dogs and cats.
