I was planning to purchase learn to read type books for summer and a friend let us borrow hers the weekend school finished. IJ was immediately able to read them. I should have started this back in December when he started spelling 3 letter words but I didn't realize the first reader books started so simply and that this actually qualified as "reading." One problem is that after he reads a book once he has it mostly memorized and then frequently guesses at words rather than reading them. This video is from last weekend with a book he had never read before.
