Besides children’s bonds, grandparents have a range of investment options to support their grandchild’s financial future. Brokerage accounts, such as custodial brokerage accounts, allow for investments in stocks, mutual funds, and more. Custodial individual retirement accounts (IRAs) are another option if the grandchild earns income through a part-time job. 529 saving plans and Coverdell accounts are specifically designed for educational expenses and offer tax advantages on investment earnings.
