I was going to chime in earlier but I didn't want to bias you Ianfan.

But since the others (ha ha, you all are now "the others"-when does that bugger start anyway?) are thinking along those lines.
You should get her tested by a 'Behavioral Optometrist' just to see where she stands. DS12 never did the therapy, time and regualar life just evened him out over the years - but it sure messed with his head to not be able to do a simple thing like read!
Same for our little C.

Although there may be a more serious processing issue, but we'll see. We did opt for the therapy to be on the safe side, plus all this was affecting her confidence and she COULD read! It was just harder than it should have been(is)!
She loves, the Dr. and I think she's pretty great. We have great hopes.
