The point of the 105 dead children was to show children can be severely affected and don't have magic immunity. 500K children have been diagnosed with COVID, with varying symptom levels. We have 200,000 dead overall in the USA, so it's not just a matter of 105 dead children justifying lockdown, it's all those other dead people you seem to have forgotten about.

Also FYI, you can't hug your family member anymore once they're dead.
