Make sure everyone has the cleaning supplies they need to do their jobs. When time is up, allow a few minutes for last minute touch-up. Then stand back and join in a round of applause for all who did so much in such a short time. A great lesson in the power of family teamwork. Cooking time is for everyone.
Some families develop favorite meals because there's a role for everyone.
Try sharing jobs with your children, so you can use work time for family talks. It's a natural time to share the day's events, or to bring up some of the serious matters you need to raise with your children. Or just share jokes and laughter together. Praise and hugs. It's the effort that counts most when kids do family chores.
