Nanny Needed

My9-year-old has a mood disorder and autism spectrum disorder. She is highly intelligent, can be very sweet and helpful, and has come a long way with behavioral therapy, however she can still have instances of serious aggression. I'm looking for someone reliable to get my kids off the bus, remind them to do their homework, and just hang out with them until I get home (usually 5:30 PM, occassionally 8:30 PM)
