Mothers Helper Needed For 1 Child In San Rafael

We are looking for a mother's helper for 1 child in San Rafael two days a week. We would prefer a nanny who does not smoke and who is comfortable with dogs. I work from home and would like my daughter to feel like she still has me available to her but need help when work tasks come up during the day. My daughter is 1. 5 years old and so much fun to be around. I have been working full time and caring for her since February. Work has picked up for me a little and I could use some extra help.
