this might not be the answer for everyone...but it works well for me. i give out a small "prize" for good behavior (its never candy or food - stickers, pencils, plastic jewelry) about three days a week. I have a few who like to show out when Mommy arrives, so I never give out the prize until they are about walk out. I usually say something like, "Okay, lets get our coat and hat on, and when we're finished we can take a look at the Treasure Chest". That gives them the cue that misbehavior at this point would not work in their favor
