My kid lost her 4th tooth and I tried to teach an economics lesson about the Law of Diminishing Returns

So my 6.5 year old just lost her fourth tooth. Like most parents, I gave her a decent amount ($20) for the first tooth she lost, probably $10-15 for the 2nd and maybe I gave about $10 or so for the third. In order to start weaning off, I wrote her a little poem with an attempt to teach about the law of diminishing returns.What do you think?http://ift.tt/2dzlmim via /r/Parenting http://ift.tt/2etjqwz
