Babysitter - Full-time / Part-time

We need a nanny to care for our 7 yr old son who is on the spectrum and has ADHD. He has some aggression when very stressed and training or experience with kids on the spectrum is preferred. Must be a very calming and non-alarming personality. For the 4 weeks, you'd be playing at home, doing light meal prep, cleaning up together, reading, some light learning, going for walks, field trips, etc.
