My neice who was grade skipped 2 years in elementary school went to a college where they offer a "Gap year program" which allowed her to continue academics at the college level in areas where she did not have time to focus on as well as do some group traveling etc as part of the program. This Fall she will start university (different one to where she is now) to pursue her degree in Economics.
The important thing about this experience for her - the Gap year program she pursued had mostly 15-16 year olds. Her interests and career goals changed during that year - due to peer influence or more exposure to the world or more maturity? - she wanted to pursue International Business all through her teens and now she figured out that she loves Economics more.
So, just let your child lead the way for now. Because it is way too early to worry about what the future brings when the child is not even in K yet (I am like you and worry a lot about such things too and I am told this by too many people too many times!).
Good luck.
