We just divide and conquer. For example, I might start out by cutting the grass and she'll start dusting, vacuuming, and mopping. After I'm finished and showered, I'll clean the bathrooms. Then, after dinner, we'll clean the kitchen tip to toe.

We have variations on this routine, and the kids are old enough now to start pulling some weight. Key message is that it is OUR house, not Mommy's house.
