Nothing's hard and fast about this, but it certainly sounds like having testing done for both kids would be advisable, when the time comes...

Oh yes, we have the intention to test DS when he is close to 3 years old. I am pretty certain that he is GT too and that he most probably benefit from starting the school one year in advance (at 3 instead of 4 years old). It is simply that he looks a little bit less gifted... but after reading your link I start to doubt my judgement.
