How to introduce kids to flying?

I have a 6 year old son.
I'm only a student pilot.
However, in my youth, I thought flying was totally cool - yet
completely out of my domain. I lived in a very rural area
and we didn't have much money as a family.

I really wish I had been exposed to it earlier.
In fact, I wish I would have made a career out of it.

My wife is a little "weary" of flying, having the "nervous wife/mom"
syndrome.

I'd like to introduce aviation (not just flying) to my son
over time.

I'm wondering if anyone has resources or recommendations of how
to do this effectively without being overbearing, being realistic,
but creating true excitement.
I mean, I have some idea, but still, input and perspective from
other sources can be invaluable!

Are there books covering such methods?

Thanks to all in advance!
