I can say I was talked with a lot as a baby and kid, I played an instrument from elementary through high school along with various sports, and I still feel guilty staying inside watching TV on nice days, but I don't think anyone calling me smart hurt me.
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!
So going to institute this 'Clean your room' check list for kids! Laminate and use a dry erase marker. =) No more checking and rechecking - "Is my room clean yet, Mom?" Can I PLEASE go out side NOW??" Don't call me until the checklist is complete :)
