Let's face it - early books can be dreadfully boring. I would keep reading all sorts of things - easy books, above level, street signs etc. he will take off when he is ready. DS was a perfectionist at that age and wouldn't read if he didn't know ALL the words on a page but was quite clearly reading along. He loved anything from Pamela Allen picture books to Enid Blyton... at 5 he now reads at a 13yo level. I definitely would remove the rewards from reading as it is more likely to turn him off reading. Reading is supposed to be enjoyable on its own smile
