Any books for kids about not being wasteful? My 4-yr-old son will take our newly purchased shampoo or hand soap or toothpaste or paper towels or duct tape or baking soda, you name it and then proceed to use them all up to conduct “experiments” when my back is turned. Argh!!! I’ve explained it’s wasteful, that I just bought that, and that he’ll need to help pay from his piggy bank to replace it. Nothing ever seems to work. Any words of wisdom to help him grasp this concept?
