Probably the most remarkable thing DD memorized was the US presidents in order at two. She is four now and can still do this. She knows even more about them. She can give a brief fact or two about each one. But, she is constantly revisiting them. The same is true about the solar system.
She also memorized the US states in alphabetical order shortly after two, and while she could tell you a lot about each state we have visited, which is a lot, and could tell you the names of many states, she could NOT list them in their order anymore. She also was obsessed with rocks and crystals at one time and could identify 30 or 40 in her collection. The other day I was not surprised when she confused some of them.
I know I have also taught her things to memorize for fun that she has forgotten. She used to be able to say the lord's prayer and pledge of allegiance and had memorized the majority of Little Bear. I am pretty sure she cannot do these anymore.
She is a quick learner, though, and could probably memorize that stuff again quickly again like she did the first time if she wanted. I always figured she would forget a lot but would benefit from relearning things over and over. I think she held on to the presidents because history is such a passion of hers and they just keep coming up.
