Hm... I can't really help here, as I only have my own experience and I was an avid reader, teaching myself to read (both English and German) only a few months after learning English - I was about 5 or 6 years old. I suppose that one of the important things is - do not force him to read, you could put him off reading for life! Encourage him to read and discourage his watching TV, but make sure that reading is fun and not an onerous chore...
