my wife and I have a 4yr old girl. we teach her a lot at home and are heavily involved in her education. the internet is extremely powerful in this regard. Khan Academy kids, for example, a free resource that has already taught my daughter the basics of reading way before her schooling could have. we are there with her to amplify the ipad, and we read to her all the time.
she also sits with me at my trading desk for 5-10 mins a week and i talk to her about charting and we look at candlesticks together. i guess my advice is, put everything you can into their education, because nobody else is going to teach them what you can.
