I went to a grandparent's day lunch at the local elementary school recently and my 5 year old's friend had a lunchable,  some multi-colored goldfish, a juice box and a wrapped snack cake. I didn't realize junk like that was so popular in school, but you see the same thing regularly that I saw this time it so it may be prevalent and widespread. This little girl was petite three years ago, but is starting to put on weight. Now I know why. Parents have to be stupid to not think about the energy needs of their kids during the day. That must be the worst when you know a kid is hungry and you can't do anything about it.
