Flexible Hours - Nanny Needed

We are looking for a nanny for our two lively boys (4. 5 and 14 months). Ideally two full days a week with occasional availability on the other week days. Our 4-year-old is in preschool for most of the day so majority of time will be spent with our 1-year-old. Light housekeeping would be wonderful. Position could grow with time as life gets busier. We would prefer a nanny who is comfortable with pets.
