well, hot sauce he likes, and we tried this other stuff that you paint on the nails. We borrowed this plastic thumb guard from my sister, and he was able to get out of it. I think motivation is the key...Yoda motivation. :-) I'm putting a band-aid on his thumb and if he can keep them on for five days, I'll let him open the box and try it on. I hope it works, but I'm not stressed out about it. It's a challenge more than anything.

I have no problem bribing kids to get them to change their behavior. ;o)
Well I did it until I was 11 with now ill effects, heh.
It took until I was motivated. The paint-on stuff was for kicking the 'not even thinking about it' part of the habit. I would not be thinking about it and suddenly there was this really bad taste. After some months (took a while) of that the habit was gone.
