Transposing numbers (19/91) is not considered dyslexia. When a child reverses letters or numbers, even if only once in a while, you know that there is stress in the writing systemâthe child has to think about the direction of the letters rather than the content of the writing.f your child is dyslexic, you have found that just having them read to you more doesnât help. Youâve also found that regular phonics programs donât work because either they canât remember the sounds of letters or they can remember the sound and they can sound out the pieces of a word but cannot put it into a whole.
