Babysitter Needed for my Children

We are looking for a great nanny for 1 baby in Port Hueneme. We would prefer a nanny who does not smoke, who is comfortable with pets (one small dog) and who is CPR certified. Would occasionally need help with a 4-year-old but he would be in school most of the time. Would just be on days he is not at school. Hours are flexible but would ideally be Mon-Thurs 10AM-2 p.m. I work from home so will be around the entire time.
