For the first week of school, I found myself arguing with the kids about which snacks they could have. I wasted so much time trying to explain what was healthy and what was not, so I made a list of acceptable snacks. Then I made this picture "menu" so the kids could choose for themselves. The first few days we used it, they tried to ask me if they could have Oreos or candy. I just pointed them over to the pictures and told them if it isn't there, they can't have it. Now they take care of their own snacks and I have more time to get the smaller kids theirs.
This list comes in handy when I am making my grocery list as well.
