I think I'm also a little mad at the school for not seeing it sooner. The K teacher said it would be fine and she would outgrow, but 1st and 2nd were always complaining about her behavior. Even now, they have implemented a behavior plan, but if it's ADHD, it might not be possible for her to meet those goals without medication, right? It wasn't the school saying we should get her tested, it's me trying to rule things out that have brought us to this point.
And of course, part of me hopes it is like that. That there might be a medicine that could help us immensely. And is ADHD a qualifier for an IEP? I'm not against that, I DO think Butter needs individualized attention...but I'm also worried about if people (adults actually) will treat her differently if they know...and what if the medication works and it turns out she's even more gifted (she scored at the top cutoff between our District's gifted/pg) and the school still can't meet her needs? 
There's just so many factors and I'm still confused and unsure...
