Aculady, I think you are spot on! My DD does the same thing, though she doesn't act out, every January she complains about school and how easy and boring it is. It hasn't been as bad this year, because she was grade skipped this year. She only complained for a short bit, but ever since preschool, every January we have seen a cahnce in her take on school. This was the first year that it has been short lived. I really do think that every year she had hoped to learn something and then the newness of the school year has worn off and reality sets in that it's the same thing! This year in fact, when in her slump, she cried and said, I just don't understand why the school isn't capable of teaching me something I don't already know! How heartbraking to hear!!!! While you son may just be showing it by acting out, it certainly worth looking into that it isn't out of boredom!
