A well-known psychlogist and GT/2E expert succinctly summed it up this way at a talk I once attended: an ADHD kid wants to sit still but can't. A GT or kinesthetic-learner kid likes how it feels to move.
I love this! This is actually how my ds6 describes his constant movement. He says it feels good and that he thinks better when moving. He was concentrating on a computer program very intently yesterday, and I just had to laugh because his mouth and body did not stop moving the entire time. If I'd made him be quiet and still, he would have had a harder time learning/completing the assigment, and it would have taken 5 times longer!
I have to say my ds6 is still exactly like your dd. He always has been. I always thought he didn't need as much sleep as other kids, but for him I've come to learn that he does need the sleep-it's just harder for him to get it because his mind won't shut off long enough for him to fall asleep. The sleep thing is much better now and has been for about a year.
He is much calmer, less fidgety, and sleeps better when he has a lot of physical and mental stimulation throughout the day. It's exhausting as a parent, I know. Good luck; she sounds like a normal, gifted little girl to me.
