As I was saying though, Riley enjoys money - coins, bills, she's not picky, and if you ask her she'll probably give you "Fourty-dollars" which might be a few pennies or a dollar bill. Now because she is a genius, not that I'm partial, she can tell the difference betwen the coins by name, but by value now we haven't quite mastered that yet and I'm really not sure at what age kids usually grasp that.
But on our trip to Branson a few weeks ago - Riley did really learn the value of a quarter. She knows you can get something out of one of the machines (usually - some of them are .50, .75 or even 1.00 - crazy I know), ride on something like this crazy pig pictured above (but sometimes you need two quarters - sigh inflation) and she might even ask you if you have any quarters so she can feed the fish.
Went to the Butterfly Palace where I laughed because they expected her to put on 3-d glasses and watch a 20 minute movie about metamorphis before going in to the actual butterflies (if I remember correctly she HAD to go potty 3 times during that - don't think it kept her interest)
