The only two people in my family who would do this is my little autistic brother, and me. Of course, he stopped chewing his shirt after a few years due to my parents constantly telling him to stop. he chewed on his shirt, pacifiers, his little siblings bottle nipples, straws, etc. But it took me literally years to stop chewing on stuff. I stopped about a year and a half ago (I am 20) and I used to chew on my shirt, toy parts, plastic straws, backs and lids of pens, pencils, etc. I still chew on ice frequently, and I like gum.
