Start young with ‘helping’.
Mine range between 12 and 16 in age.
Generally I say - this needs doing before the TV/PS goes on, and I mean it!. Their desire for the TV or PS is so great that they can do a few chores and their homework in no time now. I have had the - it’ll take you less time to do the job, than argue with me about doing it, conversation enough times, that they don’t bother arguing now.
They are pretty good to be fair.
I explain it as teamwork.
They are more than capable of cooking, cleaning, recycling, putting bins out, cut grass, putting washing out, bringing washing in, load dishwasher, unload it, do an online food shop for a week etc . The only things they don’t help with is ironing and starting the washing machine off. I am not confident enough in them sorting clothing properly at this stage. Particularly my clothing😬.
It has taken along time to get here, but it’s worth it. I do feel I need to branch out a bit into changing lightbulbs, change a fuse, turn a stop cock off and very light diy. I’m not sure I’m ready for that quite yet, but I recognise the 16 yo could be learning a trade college, so possibly it’ll be ok. They done a fair bit a cubs and scouts.
My oldest now realises how little some other kids do, but realises that transitioning to uni will be easy in terms of keeping himself/room clean, fed and tidy.
It is life skills.
