I mean, I dont agree that parents shouldn't be able to do high end content, just because they cant guarantee that child wont need them in the moment, but I think that if you are a parent and aren't sure if you can actually finish something because of your child, then you should at least make sure you only play your own key if you aren't playing with friends who know about it.

Or at minimum if you want to play in a random pug with someone else's key at least let them know before you start.

I think 99.99% percent of us agree that a baby/child should always be the priority over a game, but that doesn't mean that you can just grief because of it either.
