Upon reflection, the CD analogy is actually flawed. The problem with it is that once a friend has traded for a particular CD, they'd have no need for another of the same thing. So if K had 1 more to trade or a 100 it wouldn't matter ... her friend would rightly say, "I don't want it, I have one. I won't trade you anything for it." That's an example of instant devaluation due to complete satisfaction of desire.
This is really hard ... another thought that came to mind was trying to "buy" from K something she really values, but using a scrap of paper. But that's too abstract ... she'll say "But that's just paper, while a pound note is real money!" The pound note is also just paper, but it carries value because we people agree to view it as valuable.
Somehow -- and I honestly don't know how to do this -- we need to come up with a way to show that the value of some commodity diminishes as the quantity of that commodity increases.
Or we could just let her be a little girl. :-)
