Just an idea for you ~ an alternate way for him to get his servings of fruits and veggies is to give him V8 Fusion Light. It tastes great (the kids love it as it tastes like fruit juice) and they get a full serving of fruit and vegetables in every 8 oz. glass. I know there is a Strawberry Banana (which will still have some acid), a Peach Mango and I think there is also a Berry. The Light contains much less sugar than the regular.
