Nanny Needed For My Children - Care.com : Job Details

I am looking for someone who can sit with my son (8) two afternoon/evenings per week (three hours per day, six hours max). My son is on the spectrum, but is high-functioning. He needs support with homework while I am at work. I do have a 13-year-old, but he is pretty self-sufficient. The 8-year-old is the focus.
