Uh Oh Jar - LOVE this idea. It was getting hard always sending someone to their room or to the corner. Nothing seemed to change - but now...I'm making a consequence jar like this. Whining? Pull out a consequence. Talking back? Pull out a consequence. Not picking up your things? Pull out a consequence, maybe you'll get "Your lucky day. No consequence THIS TIME."
Cute idea :: every time you measure your child, write down what they want to be when they grow up! But maybe write it in a book or something so as they learn to read they don't just say what the wall said from past years...keep it interesting :)
