Just Wondering

Just wondering why children love to eat non-edible items. I am wondering, because Elle broke open and ate the contents of a glow stick last night; and today she ate some of the packing peanuts from Johnny’s birthday presents. When I asked Elle why she ate them, she said, “They pop really cool in my mouth.” And since her answer did not clear up any of my confusion, I am still just sitting here wondering why children eat non-edible things.
