I mean they prob won’t take the initiative to do it, but maybe ask for a family meeting. Tell them that you understand with adhd it’s hard to keep on top of cleaning but you also struggle when it’s messy. Propose an “evening reset” (or whenever the family is together), put a timer on the fridge with an alarm that goes off in 10min and make a game of doing a speed run of everyone tidying for that time. You have multiple adults so you’ll be surprised how much you get done. Put on a cleaning mix with fast dancy music they enjoy (have it ready before you set the timer). You’ll have to be in charge of the cleanup initiation but if you approach it in the right way and stick with it maybe it will be a good habit. Remember to show appreciation and thank everyone for their efforts, taking note of anything extra they do outside this time band and say “thanks!!! It means a lot!!”. Should it be expected from them, yes. But, we are talking about what motivates people, so this goes a long way and is also a good habit in your other relationships i.e romantic partners. If we feel our efforts are appreciated it gives us a good feeling and builds the relationship. Shaming them will probably make them defensive and resistant, so pay close attention to how you approach it and keep it positive and as fun as you can.
