Since you know you'll need to begin spending your savings in four to five years, be conservative. Keep your money in high-yield money market funds (you can find the ones paying the best interest rates at www.ibcdata.com), treasury notes, certificates of deposit and series EE bonds. The steps to open these accounts are quick and simple and can be completed right at your local bank, but you need to start very soon. You should also remember that as the cost of higher education increases, both the government and colleges are beginning to offer more financial aid in the form of grants, loans and work-study programs. More than half of all undergraduate students are awarded some form of financial aid, so the odds are you won't have to shoulder the financial burden on your own. The most important thing, though, is for your daughters to see you taking responsibility for your money. True education starts with messages that are passed down.
