They have chewing necklaces that are a lot like old phone cords in that they are a plastic spiral. I got two for my son when he was about that age. He never really used them until he rediscovered them recently. One thing he HAS chewed constantly is the straw on his straw cup. We buy the take and toss kind of cups. They come with thick plastic straws, but we use disposable straws. The straws from Target (up and up) are a little stronger and don't split like some of the cheaper supermarket ones do. They usually survive all day. Good luck!

How about one of those teethers. Some of them are bumpy so it would satisfy a sensory seeker as well. Just a thought

Yes therapeutic chew jewelry bracelets and necklaces.

I'm wondering if he just got excited having fun with Gma and became overwhelmed. I'm not a huge fan of artificial colors and sugar...but, hand biting isn't good either, so in this instance I might try a little War Heads spray on his tongue right before engaging in playful behaviors to give him a quick oral sensation and help redirect his senses. Definitely, as a speech path, I'd like to warn you to get rid of the passy now to avoid costly dental work/tongue thrusting behaviors down the road. But, still... as a speech path who's also a momma to Steven...those suggestions are always more easily made than done, right? hahaha. You definitely don't want him to figure out the high he will get as adrenaline and other hormones kick in upon biting, which is problematic for so man. Man! The issues we all face! Still! How awesome to have a forum to brainstorm! If he does it again, look to see what occurred immediately before the biting. Include all the sensory components...was it noisy? Lots of lights? Any smells? All of those things can add up to bigtime sensory overload.

Talk to your OT about a sensory diet. There are a lot of options for oral sensory cravings.
