B.M.
I would adjust my mirror so he could see me in his in the back seat and talk to him. At first he would just get mad and cry more. After awhile he would watch me and realized he can see taller cars and traffic lights. Now he loves being stuck behind school buses. Any thing he can reach out to touch might help. I had a box on my back seat and my son spent the whole ride touching the flaps. I felt bad taking it out.
