I know every child is different but I will say this: Isaiah is 11 (almost 12) he has struggled with reading for a long time. Today he struggles with the comprehension part. His reading struggles have made the rest of his learning suffer. If he cannot comprehend what he is reading he will never pass other subjects as they require reading, recall & retell. Prior to the comprehension issue & back to the sounding out and putting words together: this also made the rest of his schooling suffer. He has been going to ST since he was 1. He also goes to a tutor & stays after school 2 days a week to learn different strategies.
Having said all of that, maybe look into having her evaluated by ST. Especially since she seems to have regressed some from what I am understanding in your post. Over the years they have taught Isaiah many things to help him read (sounding out letters, words, meanings, comprehension etc).
I am sorry that she s having a hard time. I know it is not easy to watch nor is it always easy to find the answer. .Many hugs.
