I trust you more than the psychologist, whom it doesn't sound like has much experience with 2E kids.
Erratic, glitchy performance is the same thing that has set off my mom-gut. I think that's a valid reason to suspect something 2E-ish is up. Your DD's lackadasical attitude would also make me ask questions.
Have you asked her about how she feels about reading? If it's hard for her and why? I wonder if maybe she is old enough to point you in the right directions.
You might consider consulting with the Eides. I have heard that they can do phone consultations (though I don't know this for a fact), and maybe they can make some suggestions? I've considered trying to speak with them about our DS6, but first I'm going to try the local place--with the tester's ID that he's HG+, to try to make it clear that his "low performance" will be relative to his capabilities, which are higher than average.
My big worry is that they'll see that he's above average and think nothing is wrong. But he's not much above average, and certainly he resists reading. Given his high WISC scores and his weird glitches about both reading and math (and writing, for that matter), I feel like something is up.
I wish I had more help to offer. I definitely think that if you feel like something isn't right, you are doing the right thing to pursue it. You certainly don't sound like a crazy, pushy mom to me. No way!
