At 11 years old, ds3 was ironing his own school shirts - I went on shirt-ironing-strike when ds3 went up to senior school, so all three dses would be in proper shirts, and I’d have been ironing 20 shirts a week, including dh’s.
To be fair, I probably should have done it sooner, so each ds started ironing his shorts when he went to senior school - believe me, I know that was wrong.
Anyhow - I to,d the dses that they were responsible for ironing their shirts each weekend. They had a bit of a confab, and decided a better solution was a three week rota, so each weekend one of them ironed 15 shirts - which I thought was bonkers, but their choice.
They stuck to it all the way through senior school, and when they went off to university they knew how to do laundry, iron, cook and clean.
@Buxton22386 - your son needs a stern warning - his attitude is unacceptable, and if he cannot behave himself in a civilised fashion in your home, he can find his own. And from now on, since your system is so fatally flawed, he can do his own fecking washing and ironing from now on - no ifs, no buts, and no going back on this if he apologises and puts on a repentant face.
He needs to learn the life skills of keeping his own clothes clean, and you need to toughen up and give it to him.
