Might want to look at I savings bonds. They aren't paying much of an interest rate, but the inflation adjustment is higher than treasury notes. Plus income is deferred until you wish to cash them and I believe a beneficiary would get the stepped up basis. $ 10,000 per year per person limit.
Wish now I had bought more in the late 90's, early 00's when interest was 2,3,4 % over inflation. Everybody laughed at such a "Grannie" investment, but now they are paying 6 or 7%
