Carrie -
Sounds like he is doing WONDERFULLY @ home! I sincerly doubt he would have ever been exposed to that lesson at this age - or been given the time to think about his own thoughts on "king for a day" in PS. So happy for you guys!
You could have some fun with your "little nazi" and have him help you develop house rules for the older ones - lol I'm sure they would "love" that!
He could then see what happens to the dictator that sets such high standards & harsh punishments. lol
