It's not your childs fault just a difference in brain function. I have one family member who felt ashamed at being dyslexic and so struggled through school. However, my brothers friend had dyslexia and he got added tutition and went to university and is now a successful entrepreneur. So the best approach is the latter.
Once upon a time many children went through school struggling with their work and falling behind because of dyslexia, I have two elderly neighbours who come to me to write letters and fill out forms because they were overlooked at school and just forgotten. Your child isn't stupid their brain just processes things differently and they can learn to overcome that.
