Brainwash convince your DCs - from an early age- that housework chores are actually really fun exciting games.
That way you will end up with a 5 yr old who sort washing, oputs loads in the machine and puts machine on, hoovers, dusts, and pairs up socks every weekend while you MN.
Also train them into using the dvd player and nagivating to the cbebies website on thier own, allowing you to have uninterupted lie-ins on the weekend.
