Each week my children have a list of responsibilities they must do, including keeping their room tidy, vacuuming, and various simple chores. They do not get paid to exist, so they are not given an allowance unless they elect to pick up extra chores from a separate list.
My son very easily completes his basic list each week and often adds extra chores to earn money. My daughter, however, chooses to do the bare minimum, which is fine by me — and my wallet.
My son is great with things like organising and picking up. My daughter hates organising with a passion, and would much prefer to quickly do the dishes or fold laundry. I give them tasks I know won't stress them out, which results in less whining and complaining.
