My DD 3.5 has been doing the code writing for awhile and has just started reading, so yeah I 'm thinking too that they go hand in hand. I bet your DD will be reading soon!

I have to ask if your DS is Hyperlexic by chance. My DS has been dx'd with it and started reading his first words around 15 months. If your son does have it, I'd love to hear how he progressed with it and when he started really understanding what he was able to read. If you have no idea what I'm talking about, just ignore my crazy ramblings!
