DS8 was always very independent about his play and everything, so he was "reading" independently even before he could read -- he played with my books from the bookcases he could reach, and along the way he learned to read them. He read the numbers (page #s and chapter #s and any other #s in books) first, from about 18 months, and by 2 1/2 to 3 he was reading everything. Of course, understanding most of it came along later.
