How many kids under the age of 18 got COVID and did not die from it, but spread it to older relatives at home who subsequently died from it? I have to imagine

How many kids under the age of 18 got COVID and did not die from it, but spread it to older relatives at home who subsequently died from it? I have to imagine that parents with kids who are struggling are angry. And that parents with kids and grandparents at home are relieved that they don't have to one day explain to the child how their grandparents died. If I were told such a story, I would believe that I killed my grandparents.
