Thanks! Now back to your regularly scheduled conversation...
FWIW, in re to the original question, I too would be very hesitant to do any type of testing with a child as young as the OP's child. This is not b/c I doubt your assessment of your child or b/c I don't believe that young children can be gifted. It is primarily b/c I don't think that the scores are particularly reliable at that young age and b/c you will likely need to retest later anyway, which is quite expensive, should you need scores for school advocacy purposes. I don't believe that I would have done anything differently w/ my children had I known that they were gifted, highly gifted, etc. at that young age anyway.
Like others have said, probably b/c this board leans toward child directed approaches, many of us may have tended toward just taking our kids places and doing things that appealed to them -- gifted or not. My oldest, for instance, has had a major passion for marine biology since she was a toddler. We took her to I-max films about the ocean, bought her books and toys about marine mammals, she's been a member of the Save the Manatee club since before kindergarten, etc. It fed her interest but I wouldn't have thought about curriculum per se at that age. Good luck!
