Love this thread so much fun to read. For us the real shocker and reason we tested DS6 IQ at 4 was after we realized he knew all the states just by shape. I only knew after he tested me w/the back of the state flash card. He asked me what one was and I was like "I have no idea". Then I asked him and he knew all 50 just by the shape. That was when I told my husband we have to test his IQ. Of course there were other signs but this one was really "freaky".
