Childcare Needed - Full-time / Part-time

We are looking for someone to help watch our 3-year-old daughter Mondays and Wednesday from 10 a.m. to 2 p.m. Mom will be home but primarily caring for our 6-month-old who does not yet nap independently. We are hoping to find someone who would also be willing to babysit both girls on an as-needed basis. We have a cat, so pet-lovers only.
