I think somebody may have touched on it, but I remember reading somewhere that for a kids bow, you want to overbuild the crap out of it for two reasons.
(1) They are going to beat the bow up, and it needs to be durable to be able to withstand a child's wrath.
(2) If very overbuilt in length and width, then they will be able to grow through the bow
slightly slower than if you made it like we make bows for ourselves. As their draw length increases with how tall and strong they are, the bow will compensate easily over time. It's a simple matter to make a few bows, built this way, and have them last from 5-6 all the way until they want to start making their own bows to their liking. With this sort of construction, a bow might last longer than their clothes.
