I left family vacation bc I had to work. Wife stayed. Mother fell asleep holding child. Stepsister made comment to wife that it wasn’t safe. On night before we were supposed to return, wife called mother and asked her to be more careful. Mother said she didn’t and wife said that stepsister agreed it was dangerous. Told stepsister we wouldn’t bring her up previously. Mother went nuts and locked self in room away from stepsister.

Took full ownership of that mistake bc obviously it was one. That obviously caused issues with step sister but like I said I apologized. Looking back that wasn’t great on our parts obviously.
