Don't Grumble, Say Thanks!
Choose one day to track your family's thankfuls and grumbles. Give everyone a few popsicle sticks with their name on them. Every time someone says "thank you," they get to put one of their sticks in the jar. But, anytime someone complains, they have to pull one of their sticks out of the jar. At the end of the day or week, see who has the most sticks. Mom and Dads play, too!
