Ds2 is Year 11, dishwasher as part of a rota so 3 times a week. Strips bed and puts it in the wash on a set day per week. Whilst he is at school I dry the bedding, wash and dry the bathroom towels dump them in his room, he makes his bed and folds and puts the towels back. His room is tidy, no floordrobe as he has a specific drawer for worn clothes. Every morning he folds back the duvet to air the bed.
Puts all his laundry into colour coded baskets. Sets table, gets drinks, clears up afterwards as part of a team effort. Is responsible for a kitchen bin which gets emptied on set days twice a week. One of those days is the bin collection so he puts the bin to the end of the drive and brings it back in. His brother (now at uni) was responsible for the other kitchen bin for recycling, Ds does this one too when his brother is not home.
He will drop everything to help unpack food shopping, do gardening stuff, tip runs etc. Never complains. He makes his own breakfast and snacks, usually helps to make dinner but is having a year 11 break from that whilst he concentrates on revision. He would make his packed lunch but Dh is doing it as it will be the last few months before he goes to sixth form and Dh is cherishing this task.
I think the main thing is understanding he is part of the family and we all do stuff round the house. It is a bit different for me because I don't work so am home to do stuff, but he and Ds1 used to make a family dinner every Friday night by themselves.
Your son can learn to load a washing machine and put it on. It is his fault his sports kit didn't get washed. From now on he can be responsible for his uniform wash and his sports kit wash. He is supposed to be learning to be a functioning adult. He can start here.
