ooo i like this idea of clipping kids artwork under their pictures. Another idea I just had is to put all their drawings and artwork into expandable folders and at the end of each year make a book out of it. :)
Good to remember, when you are having a bad day would you want someone to make it WORSE? Kids don't always know how to say what is bothering them. Be their savior NOT their problem or antagonist. They will value you for it.
