I was diagnosed when I was about your sons age..... Honestly I have no clue what this method was or how it help you cope with you dyslexia. I know you said you read up on it but please please please just know that he will always have it and your are doing the right thing by helping him early. In my experience the only way I wanted to read or learn is when it was fun. Just get ready for a lot of serious talks at a young age like why do the other kids laugh when I read or it takes forever for me to finish reading and all the other kids are done... And don't let a teacher make fun/embarrass your kid that is the worst self-esteem issues I have had to deal with... But now I'm 19 and about to join the coast guard so just always try to do what best for you kid and know he'll turnout alright hope I helped with the emotional parent side
