I dont know what other parents do when it comes to household chores; I have never poled my friends. But I thought I would throw this out there.
Kids love to be little helpers. The younger you start them out the better.
Cleaning day is Saturday morning. No weekend fun begins until the house is sparkling (everything dusted, floors swepted and mopped or vacuumed, bathrooms and kitchens scrubbed, etc.) No one is too young too help - well except the baby but she is only 6 months. My boys scrub my floors together (2 yrs and 8 yrs) otherwise they will fight over who gets to wash the floor. Then the oldest dusts the furnature while the little one dusts the baseboards. I take care the the kitchen, laundry, and two of the bathrooms. The little one cleans his playroom while the oldest scrubs his bathroom. When we are done, they "inspect" my work while I "inspect" their work. We fix anything that is missed together. Then we go out and play.
No one dreads this weekly ritual; they even seem to enjoy it. Even during the week the kids have jobs to help me with the household. They get stickers if they do a superb job or remember to do their work without being reminded.
When we experience misbehavior, like fighting with a little brother, a great outlet for extra energy is extra cleaning. Its a win, win for me. While it discourages the behavior for my oldest and teaches him responsibility. Although this doesnt happen often. I try to think of this as constructive discipline.
