We used another large sheet to make a Fruit & Vegetables chart. We drew and listed fruits and vegetables down the side, and our names across the top. We've set a family goal to eat more fruits and veggies at every meal, and as we do, we'll mark down who likes them (with a smiley face) and who doesn't (with a frowny face). This has the toddlers excited about trying new foods, and I'll do anything to encourage that.
