My 4 year old son has recently been diagnosed. He is loves to chew and recently his main port of call for chewing is his fingers and they are becoming very sore. I bough him some chews and he chewed through them very quickly, then when I bought him a tougher chew he isn't chewing through them but I think they are to tough for him. When I spoke to the OT about chewing she had no advice. Just looking for ideas on chews that will last that he may like or who may be able to help. Thanks
