My 4 year old is eating paper. He has an eating disorder & eats only 8 8 foods but has started eating paper. He rips pages from books, I have found letters & bills he has chewed, tissues, kitchen towel any paper. Someone said they think it may show his system is lacking something WHAT? Does anyone have any ideas how to stop this. I'm having to hide anything paper when i'm going out the room. I got a call from his special needs nursery to say he's started it there too. PLEASE HELP
