Thanks for the correction! I guess I sound a bit callous in my previous post, but I'm quite happy to learn that 3000 fewer children drown each year than I anticipated (it did feel like a high number). The 800 deaths per year figure can still function as a comparison for the expected child deaths from covid-19.
This source states ~800 children deaths/year to be children (in 2014). [0]
(I am not commenting on your overall point, just that statistic.)
For reference, the CDC notes annual total US children deaths (if defining "children" as <= 14) as a little over 9000 (in 2019, I think). [1]
