IOU good times

There is a little part of me that is worried about the concept behind these IOU cards - after all, shouldn't we, as parents, at least be able to invent our own motivational treats, fitting them to our child's tastes? And actually, is it even sound parenting to operate on the bartering-treats-for-good-behaviour system? Argh, my head starts to spin the more I think about it.

But, these cards are so beautifully designed that I'm almost tempted to put the parenting issues to one side and just enjoy them for what they are - a damn nice print product.
