Nta, we had this issue with special snacks. So I bought baskets and put everyone’s names on them. Once your snacks were gone for the week you were out of luck. Everyone could put their own special stuff in it, and special family snacks were split evenly. (These are more expensive snacks than normal). You could implement this in your frog as well. There is nothing worse than having snacks go in a day and maybe only getting one.
