Hi M.,
Well.......after I tried everything (to no avail) with my 2 yr old son, I one day, out of frustration, resorted to "biting back".
Of course it was a "gentle bite", but I had to GRAB his attention to the matter that had been going on for months!
I have to say....it worked! After my initial "bite", if he bit me, or someone else, I asked him if he wanted me to bite him back....he would say, "NO, it hurt!". Then it was my opportunity to say, "Well, you are hurting mommy when you bite, you need to stop biting me and use your words to tell me how you feel instead"......after about a dozen more instances, mixed with LOTS of mommy patience and explaining.....he stopped biting completely.
Again, I used it as a last resort. Am I proud to say it? Nope, but it worked, and I know I didn't hurt him as bad as he hurt me, only his feelings.
