Babysitter Needed

We have a 7-year-old boy, 3-year-old girl and 1. 5-year-old boy. I have appointments coming up for my pregnancy with our 4th in which I am high risk, due to this I must find someone who is very reliable. My kiddos love playing outside and inside, with their toys or cats. My oldest does have Cerebral Palsy, ASD/ADHD, intellectual disabilities, hydrocephalus which includes a permanent VP Shunt in place of his head. He does get upset sometimes and will target his siblings by playing rough.
