Babysitter - Full-time / Part-time

We are looking for a great nanny for 1 child in San Rafael. We would prefer a nanny who has their own car, who does not smoke, who is comfortable with pets (1 cat) and who is CPR certified. I will be working from home, just need an extra hand while I'm working in another room! Need someone from 9 a.m. to 4:30 p.m. Open to someone who wants to work an extra day during the week, but need at least 3 days of help. Thank you!
