I've never been a parent or teacher, and have not been responsible for raising children in any formal capacity. So, my question is... Are the kids remotely interested in programming, and does it make sense to try teaching them if they show no interest? As a child, I remember pushed towards taking piano lessons and hating every second of it.
And now as a parent with kids, I wish I got a chance to take piano lesson (or any musical instrument) when young. I make kids do things that I know I didn't enjoy when young, like studying, being responsible, facing consequences. And just like me, it's a decade(s) long process.
Obviously there should be reasonable limit on how much you will push your kids to do things they don't want to do. But I believe it's every parent's responsibility to help/push kids experience/learn new things when young. Even if they don't enjoy it (if so, it should not be pushed too hard or for long), it's a success because everyone involved gets to know what the kids enjoy or hate.
I'm not suggesting scheduling every waking hour of a child for an organized activity/study. But more/various activities for young kids are generally a good thing imho.
