Fruit snacks are a powerful food. Seriously :) Last year I would give a small treat to my kiddos who were on blue for the day (we used a color-coded behavior system). Sometimes it was fruit snacks, or a pencil or a sticker - they never knew what it would be. But fruit snacks seemed to be the favorite. And so throughout the day I would remind them of what the treat would be, knowing some needed the constant reminder of what they were trying to earn. It's amazing what a fruit snack can do !
