I am finding this thread so interesting. My eldest is 9 and we only just noticed this month that we basically had no board games, and never played the ones we did. We had a brief affair with Uno when she was somewhere between 5 and 7 and that was it. It never would have occured to me to play board games with my kids. But turn taking in playground was sorted between 12 and 18 months for each of my three. Our kids have awesome climbing skills but no ball skills.
It really highlights to me how much "they taught themselves to read/math/etc" is still very much driven by how we parent. I would say my kids taught themselves to climb just about anything, to do puzzles, various other things - but I did provide those opportunities. I did not provide my eldest with any real access to money before 7 years old, or talk to her about analogue clocks, we never looked at atlases. There are lots of things that gifted kids are apparently interested in that my kids have never been exposed to even the tiniest bit in order to develop said interest.
I think we have mostly done a decent job of parenting, but we have some weird gaps in things that we have (not) done with our kids and I am sure most other families have not done things that we would take for-granted.
