sensory processing disorder.....Pica Disease
I don't eat things other than food, but I pretty much compulsively chew on things. I have sensory processing disorder, so I fidget and chew gum, etc. because I need alot of tactile input. I really love strong fruity-tasting gum, and also I have a waterbottle from costco with a chewy lid. Definitely talk to your pediatrician if you want to actually consume things, but otherwise there are tons of coping strategies to use.
Aw thanks so much!!!! That really helps:)
