Heard sylvia rimm last night she addressed many issue around de-throning and perfectionism that could upset a child like that as well. gifted kids get so much praise - that if other kids finish faster (perceived at that age as better) or they miss something or don't know all the answers it can feel like a fall from grace... if they've identified themselves as being smart but something is hard.... seems young for such a thing but i know our now 6 year old had these issues wehn she smarted violin because it didn't come out perfect the first time.. which is exactly why we started her on it (here honey - time for something you won't be perfect at - you have to practice).
