Is this a "tic"?

A couple of weeks ago we noticed our daughter was blinking her eyes a lot, like squinting rapidly. It lasted for almost a week. We thought maybe it was a nervous tic, or possibly something as simple as allergies. It went away, we didn't think much more about it.
She's doing it again. I noticed it last night. Is this something that could be part of the PDD-NOS? She's not having headaches or vision trouble or anything. She actually just had her eyes checked at school 2 weeks ago.

Anyone know anything about this?

Chidren's Hospital, here we come!

Apparently despite the psychologist telling me that the pdd-nos diagnosis was firm, the letter he sent to our PCM didn't say anything about pdd-nos. Instead it mentioned a whole bunch of confusing things, as if the psychologist still hadn't made up his mind.

Based on what the psychologist said and everything discovered in my daughter's Occupational Therapy evaluation, he agrees that pdd-nos fits so our PCM is sending us to the Children's Hospital up north to see a Developmental Specialist. They should be able to figure this all out for certain so we can finally quit wondering and get a treatment plan in place.

It could take a while to get an appointment. Please say some prayers that we can get in soon!

Guess it does make sense.

Interesting post I just stumbled across:

Someone, PLEASE PLEASE

PLEASE explain this to me. The instant we start putting on shoes in the morning, my daughter starts throwing a fit. They don't feel right, tie it again, ehhehhehhehhehhh, whine whine, complain. Same thing with the jacket. Continues until the instant I drop her off at school, whether I have to walk her in because she is screaming with tears running down her face or I drop her off because she is just whining and I can't do anything about it anyways. The instant she walks out of school she starts picking fights with her brother, lying, arguing, complaining, blah blah blah. Yet apparently between the time she gets out of the car in the morning for school and walks back out the door in the afternoon, she is a perfect angel.

Either the teacher is full of shit and just doesn't want to be bothered with taking note of any issues with my daughter because she doesn't disrupt the class whereas at least one other student in that class disrupts it every single day - or I need to reevaluate things and take bipolar disorder as a much more likely diagnosis. Because she is anything but an angel at home. Or in the car. Or in the store, or the restaurant, or anywhere else we go!

Someone please explain how she can apparently have no problems at all in school, not even with putting her coat on for recess, never pouts about anything, argues, or complains, is apparently a perfect angel, yet from the instant she walks out the door in the afternoon until she walks back through the door the next morning, she is practically impossible to deal with.

I want a video camera installed in that classroom because I find it very hard to believe that she does nothing at all but say yes ma'am, no ma'am, please and thank you all freaking day.

EDITED AFTER SOME CALMING TIME: Okay, once again the wonderful Internet has saved me from completely losing it. I know I've read it before and even heard it from our psychologist, but I needed the reassurance - this Jekyl and Hyde thing is normal with ASD kids. The use all of their energy to hold it together in school, then they let it all go when they see Mom and feel safe to do so again. It sucks that the parents and siblings are the ones who have to deal with all of the bad behavior, but at least she is doing well in school. I need to stop and remind myself that she does not mean to drive me insane, that she honestly can't control herself.
