When my son was an infant and toddler, he would often scream in the car. On long car rides we desperately asked ourselves, “Why is he doing this to us?” We didn’t know our son had autism. After his diagnosis, we purchased noise-reducing headphones for him. He reached for them in the car one day and I knew: all those times he screamed in the car, he was not being naughty or trying to torture us. The highway noise was too loud for him and he was uncomfortable.
