Babysitter Needed for my Children

Our son is a moderate function young man with Autism. He is easy to care for as he can tell you his needs and is independent in toileting, self grooming, dressing etc. But because of his autism he can't be left alone in the home. I'm looking for someone who can watch him from 9am-5 p.m. one day a week, I am flexible on the days. Duties include meal prep, light housework, and generally making sure he is safe. Most of the time you will spend just hanging out in a nearby den while he is on his laptop playing in his bedroom. Nonsmokers only please. Autism experience is a plus but not necessary.
