Sorry I have no answer for you. But my 11 month old does the same thing when he is cutting a new tooth. I usually just give him a wooden teether and he happily chomps on that.<br><br>
I hope you get some replies!
My son did that for a while, I think both to ease the teething pain with pressure and because he does love to make new noises. I did my best not to grind my own teeth because the sound drove me NUTS, and ignored it. Now that I think about it, he hasn't done it in a while! Mine never responded well to chewing on things offered, so that didn't help.<br><br>
My main thing was just not giving the behavior any attention. I worried that if it got a reaction out of me, he'd do it just to get the reaction. (of course I give him attention when he wants it and probably sometimes when he doesn't!)
