Thank you all. This is so helpful. I have a number of meetings coming up to discuss my kids and a couple of folks at the school interested in learning more about all this. I just want to be sure I'm clear (in my own mind) what we're looking at so that any gentle steering I do is in the correct direction :-). Truly a lot of the clarification is for myself, so I can feel confident in picking articles that discuss that HG profile rather than ones that fits a G/MG profile. Does that make sense?

And thank you MichelleC for the info on the 1 in 10,000 or 20,000 numbers. Its useful for me to hear, and also may be for some of the educators. Helps to drive the point home that my kids really might need something different.
