My kids had Covid already, honestly it was surprisingly a non issue.

It’s only a “non-issue” if you’ve no consideration for others. With R(t)>>1 your children presumably spread it to others unless they were completely quarantined immediately after exposure. And the children/adults they infected likely spread it too.

This exponential spread makes it quite likely someone died from the infection chain rooted in your children.

This is why the “unmask the kids” movement I see from other parents is complete nonsense. While it’s nice that kids are at less risk of severe cases, it only matters that they can transmit the virus.
