I have the same problem with my 7 year old. I do pretty much the same thing Daneen did, only I also give Eric yogurt smoothies with fruit in them. He won't eat ANY fruits or veggies, aside from apple slices, but he will drink those. I sometimes also bake cakes/cupcakes with cooked, mashed butternut squash — use a mix, and substitute a cup (or more, especially in Devils Food cake mixes which tend to taste a bit acid) of cooked squash for the oil. The squash makes the cake beautifully moist and the child has no idea it's there. And, of course, he's beyond willing to eat it because it is CAKE! The squash adds about 15% to the carb count of each slice, but it's worth the trade-off.
