Maybe try talking about it beforehand one on one with the offending aunts. I'm sure they mean no harm----- but upon realizing they may be causing it, I'm sure they would stop. It is okay to be a little protective of your child----- they should understand and respect that. Then they can dote on all of the super cute things he no doubt does!
thnx for your comment. I try to stop those jokes as much as I can, but I can't control their behaviors since he gets very angry at anything and starts to scream.
I don't think I'd like that for my little one. I mean once is okay but to make the entertainment of the group----- that is too much. I remember vividly being asked to sing "rudolph the rednose reindeer" as a kid by my aunts (4 of them) and they would do things to make me mess up the words. I got really upset. It is like one of my only memories of them from when I was really little. I'm not joking. I remember things starting years after that----- but just remember being so upset and mad at them.
So, is it harmful? probably not---- but it isn't nice. Who wants to be the butt of a joke? Good luck.
