L.S.
My daughter was diagnosed with this too in 2nd grade. I have very mixed feelings. Her case was not severe, and she was not ADD. I believe it is a real deficit but I also believe that all children likely grow out of this at some point.....before this was identified what did children 30 years ago do??? Do you see my point.
I did one session with my daughter and paid but had them teach me the activities and then we did them at home for a few months. Her reading improved, she is an A/B student now in 8th grade. She reads all the time, she loves books. I am not sure it helped or not if she had been allowed to use her finger for awhile till she figured out and mastered eye movements would she still be at the same place today? Who knows but a compromise would be to do it how I did it thus saving the high cost of the therapy but still doing the activities to promote the better eye movement.
I hope this helps, good luck!!
