Fixing misspelled name on savings bond

I bought a savings bond for my granddaughter, who is 18 months old. The registration has an "s" at the end of her last name that should not be there. Will she have problems cashing the bond at a later date?

Generally a minor misspelling isn't a problem. The Treasury would prefer that you leave it as is, but if you'd be more comfortable having the spelling fixed, use Public Debt Form 4000.
