My lovely old laptop has been given to the munchkin to use. He likes typing letters and numbers and playing a few games through the ABC TV site.
We have just spent a very pleasant hour or so gaming together. My game was WoW, his was the letter matching game.
He would yell out (ignoring the fact that we're next to each other) when he got a letter right (every time, oh my ears) and I would let him know when i needed to get on my horse and run somewhere.
We are raising our very own gaming nerd.
