As someone mentioned, stealth dyslexia can look very different in each child. Most people have been mentioning that for their children when they did learn to read it was slow, but this is not the case for all children with stealth dyslexia. My DS7 reads extremely fast (by far the fastest in his class), and he can easily spend three or four hours reading without a break (and then gets upset when we make him stop). However he struggles with other aspects such as spelling, reading words out of context, getting thoughts out on paper, etc.
