My son was just the same. He couldn't even watch some things on CBeebies because it frightened him so much. I had to be very careful of anything that was on television due to his fears.
He is 18 and overcome all his fears, he will even watch horror films , something that even I won't do I wouldn't worry too much about your grandson, he will almost certainly grow out of it.
