The name speaks for its self "Junk", but..if sweets or junk food aren't introduced early to a child, he wouldn't know what he's missing. Kids may be allowed some junk food if their eating habits have already stabilized. Meaning they can eat their veggies, fruits, and meats in a regular basis. But I don;t encourage giving junk food because it might be habit forming. So give everything in moderation. Lastly if you want your kids to eat healthy food, you have to model that behavior for them by choosing healthy food yourself.
