I don't serve juice to my son or to my dcks except on the rare occasion. Juice of any kind (be 100% pure, or juice crystals mixed with water) makes my son VERY hyper. It did the same to me as a kid. So I cut it from his diet except as a treat sometimes. I don't want to serve something to dcks that my son can't have as that's not fair. I serve fresh fruit or veggies with every meal and snack so the kids still get thier proper serving.
