My son is also 7, in 2nd grade. He gets sped help with reading, writing and math. But recently has made leaps and bounds since finishing first grade. He reads to me now! I had your concerns as well and made a similiar post quite a while ago. At that time, James Poysky sent me a copy of his work titled Learning and Behavior in Duchenne Muscular Dystophy. I found it very helpful. Try reaching out to James here and see if he can send a copy of it to you.
Hope that helps!
Hi Everyone! Sorry about the long delay in getting the behavior and learning guide wrapped up and published. I tend to run about a year or two behind on all my projects. Send me an email (firstname.lastname@example.org) and I'll send you a "proof" copy for now. The goal is to get it edited and formatted by the end of the year.
Regarding reading, I'm not sure who people are refering to when they say that kids get better at reading by the 3rd grade. Its not tru. Dyslexia doesn't just "go away". It may get somewhat better over time, but that progress is far behind where they should be and seems to be limited to word recognition. They continue to have major problems with reading fluency (accuracy and efficiency when reading longer passages), and their reading is more slow and more effortful for them than for others. Don't skimp on the reading intervention. Hit it hard, cause the brain starts to become hard-wired by the time you're about 9 or 10 years of age, making progress more difficult. Check out Jack Flether's books about correcting dyslexia. You have to do some heavy and intensive and repetitive phonics instruction.
