Ya you could go pretty crazy but for the most part, even organic children's chewables still use your basic vitamins and other minerals but for us, we try to choose the better kind in our eyes. DD2 currently take Rainbow Light chewables. They're delicious! You can check out other brands like Nordic Natural (Nordic Berries are the ones for kids) and I'm sure others can chime in on what their children take.
