Thumb sucking no more

Have you ever just reached your breaking point on something? Well, I did last week. I. just. could. NOT. look at my almost 12 year old with his thumb in his mouth any longer. We have spent almost $1000 on fixing his mouth so far, and his sucking his thumb undoes all that. Worse still, we've gone the extreme dental route twice already with anti-thumb sucking appliances, but still no success. So here we are at an impasse.
Until I found THESE:
Developed by a dentist, they are external anti-thumb sucking devices, so they cost WAY less than another appliance (although at $80 they are NOT cheap). There is one for each of his hands, and he must wear them 24/7 for weeks/months/years until he stops. And with his sensory issues, just wearing them has made for a few, ahem..., challenging days. But he is wearing them whether he likes it or not.
So for you locals, if you could implore your children NOT to mention them at all, and certainly NOT to make fun of him, that would be GREAT. He thinks they are way more embarrassing than sucking his thumb is. So if you could help in that endeavor by giving your kids the
"heads up" we'd appreciate it.

Here they are in real life. (And he's mortified that I am blogging about this.)
