My kids all do chores, they start from as soon as they can undrrstand, eg: 15month old helps pack the toys up..
They are pretty basic, pull the doona up pack your toys away, mainly to do with keeping their rooms clean, but they do put the washing in their rooms, I pack it away !!! we also expect them to help outside, if we are cleaning up they get a broom etc, we don't pay for these jobs, might be a bit harsh but i think its a part of being a family and the mummy and daddy are not the only people there who make a mess.
No flatmate/boyfriend girlfriend is going to pay them to help clean up, its just a part of life.unfortunatley!!!
