Always on the lookout for the better chore system. I know these things about chore systems: If they aren't simple, they won't work. It doesn't matter how cute or how much money you've spent on the chore chart, if it doesn't work for your family...it just won't work. AND, because kids change and lives change, chore systems must change or they quit working.
So you've assigned chores, but it's still not working for your family. The kids fight, the work is lousy and mom is tired. I get it. You're not alone. I found this secret to getting your kids to do their chores well and I promise you're gonna love it!
