The only thing that would really bother me is the eating with mouth open. Yuck! However, I wouldn't say anything to bf (boyfriend) about it or to dd either. She must be aware of it, and if it bothers her, she'll deal with it, eventually. If it doesn't, it doesn't - not much you can do about that. For now, maybe try getting together with them for events that don't involve meals? Otherwise, try not to sit opposite him, LOL!
