At what age does dyslexia start to show? DD is almost 4 and a half year and has shown an interest in writing. I haven't taught her very much but she's picked up the alphabet and loves writing her name. On more than one occasion I've found that she's written her name backwards (ie if her name was Katy she would write it YTAK)and all the letters will be backwards too. Is this normal for a preschooler or is it a warning to look out for dyslexia? Are there other things I should look out for? Or other less obvious signs?
