not sure about ohio, but here in wisconsin, you can put 'tax free' money into a what's called a 529 plan. i started it when each of my 3 kids were born. a set amount comes out each month and goes into each account. then we periodically dump money into the account, as well as allow relatives to put money into it. obviously, you can get the money back if the kids don't go to college, but there is a 5-10% penalty. you can use the money towards anything related to education (dorms, laptops, books, and obviously tuition).
i was lucky enough to have my parents cover college tuition, and i want to be able to do at least that, and possibly grad school or a private school.
