I don't know of any reason to say it can't be asked here. Orbit for Kids is available in "kid friendly" flavors (Bubble Gum and Strawberry Banana). I see nothing at all different in the formulation beyond the flavor. For the most part it is a marketing gimmick. The "for kids" flavors have xylitol as the second ingredient. The adult flavors have it as a 3rd or 4th ingredient. That probably just means that the kid's version is somewhat sweeter.
