Thanks JJsMom for the savant possibility...Interesting. Of course all morning I've been researching savants and calendical calculation!!! Hahaha...Well, I'm not thinking it fits ds. Most savants seem so extreme and are usually autistic or with some nervous/brain disorder which ds does not have....But still it IS intriguing. Now that ds is 11 and is focused on other interests, I don't see him using calendaring as much. Although now he is a complete nut memorizing baseball stats/facts...Hmmmm....When he comes home from school, I'll have to "quiz" him to see if the calendaring is still there Lol. Funny, I was looking back on a journal of observations I had written about ds. He was age 8. I had written that he had memorized all the presidents in order, all the capitals, landmarks and exact location, and is currently memorizing all the worlds countries/capitals/landmarks/locations and every countries/states/cities populations. Is this a "normal" regular kid thing??? Gifted kid thing??? Something else??? Do your kids do this??? We just have always loved his passion of learning and had never thought of it as anything else smile
