D.A.
I have 3 adult children, but I tried this. For the 4 older children, I ignored their rooms, dirty clothes,etc.,and just closed their doors. Then with the 6 year old, tried making cleaning fun and rewarding her with something special. Then try the same thing with the 12 & 10 year old. Try talking to the 18 year old boy as an adult. Tell him, using a soft quiet voice and treat him as the adult. He wants to be treated like an adult then tell him that you are worn out, tired of asking and lets try working as a team (there is no i in team approach. Hopefully he will gain respect for you and. They will all be watching him (big brother) and hopefully you will all be able to work things out. No shouting, no disrespecting, no acting out. Keeping the house clean is nice but they need to respect you and each other first. Good luck!! NanaDiane
