My DiL works with autistic children. They are very sensitive to a lot of different types of stimulation. Often they have difficulty with clothing like shoes or even having their hair combed. That said, they may respond to certain park rides that you would think they couldn’t tolerate.
Well, maybe the mother should choose some time in the future to take her son to this park or find another way to entertain him. I’m tired of people making demands for their every need or desire.
