Love the idea of a "grazing tray," that kids can help themselves to all day (with a variety of healthy fruits, veggies, etc.) I would leave it inn the fridge & she could help herself when she feels like a snack. I have yet to try this, but grazing throughout the day is so much healthier than large meals & designated snack times.
Apple Butterflies: "My son loved it! At first, he didn't want to ruin it. So first he ate the celery since to him, it still looked like a butterfly without it. Then, he ate the raisins, then a bite from each wing--it was hilarious! He finally just gave up saving the poor butterfly and gobbled it up! "-AniSarit
