Yeah, I think I posed the question just to get ideas for how others think about it. I don't have a need for him to learn it per se, I just wanted to start a discussion about how zero is a difficult concept to teach. Heck, humanity had to "invent" the concept of zero. I alluded to this in another comment, but what astonishes me about my son is how rapidly he grows and changes. Every night, my wife and I talk about how amazing he is, etc. and I can't help but think about the fact that 1 year ago, he was barely able to roll over, and that he's now running around, "reading," eating solid foods, and a full-blown chatterbox. If he's doing this much now, what the heck is he going to be doing next year? It's forced me to reevaluate my own life. If my son can accomplish all of that in one year with proper support, nurturing, and guidance, and we are genetically related (i.e. 50% of him is me), then what could I do in the same amount of time? I've resolved to find that out.
