I understand what you’re saying. But you’re comparing accepted knowns with an unknown novel virus.
Like our seniors, -Most- children/infants that die from pneumonia are immunocompromised. For seniors, flu/pneumonia is an expected end-of-life event, right up there with fatal strokes and heart attacks. Children are generally: unhealthy from birth, handicapped, chronic conditions, metabolic, neurologic, and pulmonary/heart disorders, or abused and/or malnourished (system stressed). Very high risk are American Indian, American Eskimo and American blacks (sickle cell). Comparatively few otherwise healthy children die from flu or pneumonia.
Because Americans know this, they don’t tend to freak out over flu/pneumonia deaths. Even those inflated by an endemic H1N1. But a novel virus is an unknown. And a new novel virus, that’s still in diapers mutation wise, is a huge unknown because nobody knows what it will grow up to be - H1N1 level, cold level, or Andromeda Strain level? And that is why we need to eradicate it as quickly and as far-reaching as possible.

Yes, it it an unknown. But we studied and defeated Influenza A virus subtype H1N1 (A/H1N1), and the same can be done with COVID-19. We just have to have the will to do so, regardless of the media.
