They shouldn’t clean up after us but they should share the chores for things everyone uses
I'd say the majority of the mess comes from you, your DH, and your 2 DC
I’d say if I cook a meal for 4 and they cook one for 2 then likely a bit more than 1/3 the dishes are theirs and a similar proportion of the rubbish is. Similarly if we are washing for 4 and they wash their clothes 1/3 of the lint and water that needs to be emptied is theirs. So yes majority is ours and we should likely do more often than them but that isn’t the same as us doing about 95% is it.
How much chores are your DH and 2 DC doing? Hovering, unloading, loading, cooking, replacing, dryer vent lint cleaning etc.? I bet about zero
You would bet entirely wrong. I do all cooking, OH all laundry and other stuff we share. Kids are 6 & 8 so don’t do massive amounts but they do help with dishes and keep own stuff sorted.
I didn’t say they clean up after themselves. I in fact said I’m annoyed they do half a job (wash dishes and leave on sink) rather than putting away, load dishwasher but not empty it the vast majority of the time, never empty kitchen bin. Also I know about the tea because only my Husband and them drink it and he’s refilled it every time even through he’s showed them on several occasions where spares are and asked them to do it. They drink massively more tea than him so something he normally does every couple of months he is doing most weeks.
