Ok, this is what I expect my 5,7, 9 and 10 year olds to do.
help tidy kitchen, incl, cleaning surfaces, loading,unloading dishwasher, sweeping and mopping floor, tidying away stuff that doesn't belong in kitchen
tidy hallways, stairs, corridors, play room, including hoovering
keep their rooms tidy, put dirty clothes into laundry
I have a rota system so they do different jobs on different days and they all all pretty good actually.
ds1 moans that his friends don't have to do house work.
I say more fool their mothers and that ds1 will be the one laughing in a few years time when he knows how to look after himself and his mates haven't got a clue.
They also cook dinner regularly, because they want to not because I ask!!
My 3 year old is hoovering the playroom as I type and doing a damn good job
