@Bostonian: I'll check that out. Thanks!

BWBShari: That's a great story and I bet the nature of having living, breathing animals helped keep your DS motivated and reminded daily. We don't live in an area where that would be legal, but it sounds fun!

Keeping it real and practical sounds like the trick. I like the idea of adding the goal as a reward. Right now DD's is just about the idea of having a product. If she knew it would help her get a puppy she may find that's all the motivation she needs.
