I have 4 boys. They are so different from each other it is hard to tell. I think they all have some amount of giftedness (not completely sure on #3), but the levels might be very different.
DS10 is borderline MG/HG - does well in a public school all gifted classroom - tends to be in the higher groups there but is generally well served (but with major handwriting/writing issues and some ADHD stuff - very disorganized).
DS8 fits DYS criteria comfortably (except for reading achievement scores, but math is well above minimum DYS levels). He is very spacey and diagnosed ADHD also. The math will be way too easy for him in the all gifted class.
DS6 tested bright/borderline MG (done as part of an ADHD eval when he was 5 and not terribly cooperative). He has pretty severe ADHD and speech issues. At times he looks more gifted - he is amazing with certain things that he likes - he races through ThinkFun logic games (like Rush Hour or others). His speed and abilities on those always stand out to people who see him and he is pretty amazing at just about anything on the computer or electronic, but is just not great verbally. He is learning quickly in K though, so I am just not sure on him. My guess is that he will do well in normal school, but be grouped in higher groups. He may end up needing more - he does say math in particular is pretty easy, but his abilities are nothing like DS8, so hard for me to judge.
DS3 seems gifted to me. He is the best verbally of them all (letters and sounds before 2 - very big vocabulary - starting to read now, but nothing really amazing like others here). He is also strong with numbers but maybe just now starting to show it. He is a little more balanced, but is definetly the most like DS8. I would guess that he would end up testing as high or higher than DS10 - too early for me to guess whether he would be as high as DS8.
