DS8 was/is a verbal superstar and very showy gifted. He was the three year old that could explain and build a model of a desalination plant. He's also dyslexic so there were some usual holes (hated even looking at numbers/letters). DS5 is not a verbal kid. Early on there was an almost creepy attention to the route we took to various locations and perfect recall even months later of how to get to places he wanted to go. At five he has a natural ability with numbers his older brother doesn't have. Skip counting, mental math, multiplication - he just gets it without any instruction.

DS5 has not been tested but I suspect he is in gifted range but probably with different strengths.
