<prompt> Human: So... I have two kids who will be going to college in 5 years and another in 9 years. Is it too late to open a 529 College Savings Plan for them?Note: We already maxed out our retirement contributions for this year. Also a late bloomer in saving for retirement but thats another story.  <response>: Heres a proverb for you. The best time to plant a tree was 10 years ago. The next best time is now. Its never too late. : Well after they graduate would be too late. But 5 years before they get there? Go for it.
