Kids are cute, but suck while you're travelling. They whine, they drag their feet, they throw food, and cry for McDonalds every...freaking...meal. One good way to shut em up is to pretend their luggage is a little race car, or giraffe, or a hearse. This is perfect for that, with a tow handle, a durable polypropylene shell that makes it very Samsonite Oyster-like. That hearse one really shuts em up good.

DISCUSSION
Well, and the kid won't have enough stuff to fill it unless you're going on a long trip or the kid is 10. Both would exclude the serious use of this item, because the parent isn't using this as their luggage. Plus, the wheels are probs crappy and would bind on the case with any amount of weight.
