Babysitter Needed

My son is a nonverbal autistic. Hes pretty energetic but does his own thing majority-90% of the time. He loves watching movies and going to the park, which we have one around the corner from the house. He is not potty trained yet so will need diaper changes but he will stand and lift his legs for you etc. I will be out of town for a concert with my sister that gifted me the tickets, for the day! I estimated high for the time I will be gone, it may be less than what I put! I will have access to my phone at all times!
