If it gets to the point where the mess/dirt/smell etc is affecting other members of the family?
I’d left it and left it. Things got to the point where it was foul it was becoming a health hazard. Spent HOURS and less than 24 hours later it’s a mess again what am I meant to do. This was the first time I’d given in but I was genuinely worried for the rest of the family as it was disgusting not to mention I don’t want a whole room / carpet/ furniture etc ruined so had to intervene
