The trouble is, he happens to have a (younger, fgs) sister and a lot of friends who have picked up reading pretty well with very minimal instruction and a good dose of phonics based computer . programs. We're also quite lucky generally in that we're a part of a strong local HSing network, here though it means there is a lot of frantic not-comparing going on, iykwim.
Same boat! Mine's younger sister, who is 4, is quickly catching up to him in reading. She's much more motivated and just catching on quicker.
I'm just glad he's first! If she'd been first, and reading this early, I think I'd have been a lot more worried about him.
