Parents may think it's harmless to to let toddlers and young kids drink soda or fruit juice
Which parents are those?
Keep in mind, though, there's a difference between giving your kid a 4-ounce box of Juicy Juice and handing him a 20-ounce Mountain Dew. One at least has Vitamin C, doesn't have caffeine and is an appropriate portion size. The other, well, is the opposite.
