Ask HN: How do I give my son a head start?

There are few careers around today that wouldn't benefit from the employee having a better understanding of programming and just IT in general.

As well as the fundamentals such as reading, writing & mathematics, I fully intend to introduce my son to computing from a very early age.

I was thinking that I could introduce him to things like BASIC not long after he masters the art of counting to ten but I would love to hear from you guys.

How would you suggest I give my son a head-start in an IT orientated world? He's 6 months old currently so I have plenty of time!
