Babysitter - Full-time / Part-time

We are looking for an evening nanny/mother's helper to help us with bed-time and cleaning the kitchen/living room. We have two children. 5-year-old boy and 2-year-old girl. Our son has special needs (Cerebral Palsy) but is very well-behaved and very friendly. Responsibilities include helping to watch our son and helping to clean our kitchen and living room after dinner. We also have two cats.
