Anyone have a biter?

Telyco

Leah is - big time. I constantly have bite marks on my shoulders and arms where she gets me. Today she bit Evan right on the back - poor kid has eight perfect teethmarks in his back. Is there anything I can do? She isn't doing it when she is mad - it just comes out of nowhere so I have no clue how to prevent it...other than not letting her near us. We do give her a strict "NO. We don't bite" etc but she just yells "NO" back to us, sometimes getting a little upset that she got yelled at - but then she just goes about her business.

This girl is a pistol. I can see her temper growing and she gets super mad when we take things away from her...Ugh - here come the TTwos!
