DS4.75 is also a self taught whole word reader, now at about a gr3-4 level. Phonics has kind of come along this year by itself. He also would give a stupid smile if someone asked him what sound this letter makes. He can spell simple 3-4 letter phonic type words. He hates doing invented spelling though as he knows the words aren't right (and he is a perfectionist). So I have started to tell him the harder words or write them for him to copy figuring that with exposure and use he will remember them (which he does). School might teach him the formal rules (maybe??). He is skipping K so I have started trying to encourage more writing at home.
