The thought I had was to lock them out of the house til noon or 1 then let them in for lunch and cartoons...we'll see
Just put them to work. They are old enough to run the lawn mower and week wacker. If they go door to door mowing lawns, you could make a killin! Who can resist a 5 year old with hedge trimmers?
Remember to watch for the little buggers on the roadways, they are definitively quicker now, so don't forget to lead them a bit more.
Last time the little tykes showed up and asked if they could mow our grass, they wanted $40 for the front yard, I figured it'd take me 20 minutes to do it.
