I agree that structuring chores works best, a clear understanding of who does what & when. Also.. I have a son who I think may also be ADHD like me (I just realized I am at age 56) I only get him to do something if I am blunt and to the point.. nagging, and/or yelling makes it worse. Just say something like “do the dishes b****h .. and walk away” .. and he does them ! lol
