Jtooit, you are right. Because of DS4.5 INTENSE drive to learn and his interest and knowledge in so many different from a very early age areas it is easy to compare and think DS2.5 is not gifted or at least even close to being as gifted.
Many times I am in awe and sure DS2.5 is way out there as well judging by the things he says and does. Much more insightful, intuitive, thinks about things with way more detail, picks up on peoples feelings, notices more detail etc. than Ds4.5 ever did. But I then think and compare that at this age DS4.5 was obsessed counting to 1000+ while swinging, making words, copying books on the computer(at about 32 months of age)and I think that DS2.5 can not be gifted to the same extent.
Like you said, they all are different. I also think because DS4.5 is the way he is DS2.5 might pick a different route to not have to compete. Don't get me wrong. DS2.5 is an extremely fast learner. He is reading more and more words everyday, understands how to sound out words etc. But he is not as serious about it. Last night he was sitting with a book picking out all the words he knows. Then he got bored and started to goof off picking two words and saying "all" was "soon" and "soon" was "all". Switching them all up and cracking himself up while doing it...LOL!
It is just interesting to hear from others experience what the sibling differences are. I am not having DS2.5 tested anytime soon. Probably a couple of years or so IF I feel it is warranted.
