DS is 10, unloads dishwasher (i honestly dont know why i cant stand doing it, but will happily load all the dirty items from sink into it, but find putting the clean items away mind numbing), he unloads and hangs the wet laundry, tidies/picks up everything off floors when asked, organises his wardrobe roughly, hoovers when asked.
Does it all quickly (because he wants to get back to screen time), it's really helpful for me.
Sounds like he does alot but there's still loads for me to do tho. (Bins, recycling, sort and load dirty laundry, fold away clean, wiping/dusting throughout house, hoover, moping, cleaning kitchen, bathroom & loo, lay beds daily or change bedding, cooking, bathe littlest ones).
10 is old enough to help so I've a few less things to do, we all live here.
Also kids need to learn how to do these things, as part of learning how to become fully functioning adults in future, no?
