> One of the things you figure out is that some kids aren't interested. And if your kid isn't interested in thinking about prime numbers, you're going to be hard pressed to change that. Conversely they will have interests that you don't share, and it's going to be harder for you to participate meaningfully in that beyond being generally supportive. They are individuals that way.

I grew up in a family with 7 kids and my youngest sibling is just 12 years old. I remember when my younger set of siblings were born, I was thinking "I'm going to teach them EVERYTHING I've learned at a young age, and they will be way ahead of their peers." I failed to grasp just how much of their personality is ingrained in them from their DNA and that they might not have all the same interests as me. It was a great learning experience though -- when I do have kids, I'm not going to try and shove my interests down their throat. I'm going to pay attention to what they are drawn to and give them as many resources as I can so they can pursue that interest as much as they desire.
