BTW - my 'home IQ test' is this: If you kid is advanced enough that you don't want to share his highlights with your friends, chances are he's gifted. Notice that other parents are only too happy to brag away, regardless of the effect on other parents.
I would second this. It's a good litmus test.
Most public schools resist testing for gifted until second or third grade.
My older son was tested in kindergarten, but I could've told them he was gifted when he was two. While some recommended that I try to "slow down" my son's learning (as if that were possible with a gifted kid) so he wouldn't be bored, it wouldn't have made a difference if I had. When your five year old is going up to websites to learn about weather patterns, circle time is boring when kids are guessing if it's hot or cold outside.
So my thought would be to let your wee one learn at his own pace and deal with school when it comes.
