intentional under-bite? GAH!! 2 kids; Texas 441 posts13th Apr
More and more frequently my 3 year old son is intentionally jutting his lower jaw forward, causing him to have an underbite. I'm worried he might cause problems for his teeth but if I try to say something to him about it of course he'll do it more...It's not a natural underbite, he never had one before, and it does not persist when he's at rest or speaking normally. I don't know what's up with him or how to curb this weird behavior...any advice?
