Nanny Needed - Full-time / Part-time

We need a night nanny for our child (born this Mother's Day!) in San Francisco. We would prefer someone who has experience with infants (less than 6 months old) overnight, is CPR certified & could help out with light housekeeping (baby laundry, bottle cleaning etc). Must be vaccinated & non smoking please. We're flexible on number of days per week, but am looking for anywhere from 3-5 days per week overnight.
