Not doing a Mother/son dance?

I would say he should probably at least ask her how she feels about it. It may be something she's really looking forward to.

We are not doing a son/mother but we also are not having daughter dad. I would totally dance with my mom. My mom and I are close. My father and I not so much. My FH mom said she would dance with him if I danced with one of my parents. As of right now we are skipping them unless we change our minds, haha

We are skipping those dances altogether.

My father and his mother are both deceased and we are personally not doing either. I went to a wedding recently and there was not a mother son dance and it was not awkward.

I am on the same situation!! Except the other way around.. he’s debating if he’s doing it, while I’m not and I was wondering if it’s weird or not...

I would definitely suggest he ask his mother. Even if they don't have an affectionate relationship that might be something she always looked forward to. Honestly, if she wasn't abusive or an absentee mother or other things I don't see reasons not to do it! I really don't think it's weird to not have one or the other but he should at least ask her about it.
