DS1 is in Y1. He can read very fast and fluently BUT he often makes mistakes - skipping words, mixing up what/that and when/then and how/now, and sometimes reverses the order of a pair of words "said Sam" instead of "Sam said".
He's on a reasonably high book band, but he still does make these mistakes say 5-6 times in a 32-page book, or more if he's tired. Is this a problem or is it normal at this stage? He also finds it hard to read words in block capitals. It's odd, because he learned using phonics so he should be able to sound out the words in capitals, but he sometimes struggles or hesitates with things that are relatively simple.
