Just got back from a night away with dh, timed to get back for the end of naptime, to find an empty house. Turns out Dm has taken my kids to visit my grandmother, over an hour away, and only just got there so wont be back for a good few hours. We only went for one night locally so that we wouldn't have to be away from baby for more than 24 hours. Dh is absolutely furious because he works away all week and hardly sees them. But i hadn't told her when we would be back, just assumed they would be here for naptime since i gave her the schedule(which must have been ignored. So aibu to think she should have checked before buggering off on a Sunday afternoon, or is it my fault for not telling her when we would be back?
