what kind of link do you think exists between giftedness and kids who tantrum early? i'm just curious because my 4 year old started about 3 months old. it was wild. i have always been curious about him, and although he could do puzzles at 12 months, and knew all his letters and sounds by 18 months....at 4, he doesn't present as "typically gifted" like my older son was at this age. but he has some other behaviors that make me think maybe it is time for testing. insight?
