We call this Eli's "P" toy. I give it to him on days when he is having a hard time keeping his fingers out of his mouth. I ordered this for him some time ago so he could have a chewing outlet without reverting back to the binky. It is just a therapeutic orange "P" that he chews on... it keeps him from chewing on his fingers, the playstation cord, etc.
We often put this on a nylon cord as a very loose necklace for him when we go places with it. Last week I went to my mother's with Eli and his "P" necklace. My 16 year old brother, (who also has autism,) was very concerned. "What does that P stand for?" He was very interested to know. I told him that it didn't stand for anything, it was just Eli's toy to chew on. "OH!" He said with very obvious relief. "I am so glad that it does not stand for anything inappropriate." I love you Jared, you are hilarious!
