Babysitter Needed For 1 Child In Houston.

I am looking for a sitter for my 6 yr old autistic son, he will need care on occasion when I have to work late the days he has half days or just need me time. I want someone that is consistent, I prefer not to have someone new every time he needs a sitter due to his diagnosis it is important to try to keep the same routines. Duties would be light meal prepping, cleaning, playing and making sure he does not elope out of the house. I prefer someone that has a vehicle and has had experience with autistic children.
