As long as froggy is gaining weight and size, you don't need to worry to much about the specific feeding schedule - horned frogs are pretty forgiving. Personally, I feed baby horned frogs every day and use a combination of the "15 minute rule" and common sense. If I'm tong feeding (which is much more efficient than having them hunt the food), then I feed a few items, until the animal appears less eager to feed. As they grow, you can reduce feeding frequency to every second or third day as juveniles, and then less frequently as adults....
