LE looking for a babysitter or nanny in Eastern Passage

I'm a single mom with a 10 year old son, who's autistic and likely ADHD. He's pretty easy to deal with once he is familiar with you, most of the time (he can be a little challenging when he doesn't feel safe). I am looking for occasional after school care, from 2pm until about 5:30pm when I get home from work.
