4. Re-evaluate as needed: Parents don't have to stick with one investment strategy forever. Re-evaluate annually or when children cross the next age threshold within the chosen plan. For instance, parents may to look at the value of their account and want to add more risk because their child is 7 and they'd like a bigger opportunity for their money to grow. And parents with a 16-year-old may opt to switch to a more conservative plan. Generally, even the most aggressive age-based plans will reduce riskier investments as kids age.
"College savers should make sure that they're comfortable with the risk they're taking on each step of the way," Lutton says. "If the age-based options seem too risky, you could add a cash option as a second investment in the plan, or you could add an equity option if you want to take on more risk."
