Yes.

The dangers of fever are vastly overstated. People have spiked 114F fevers and have been fine. Personally, I put "unregulated" fevers (they are regulated.... just not exogenously) in the same box as letting your kids do physically dangerous stuff without intervening. Kids need risk for their brains to develop properly. Kids likely also need fevers for their immune systems to develop properly. How could it be otherwise? These are highly adaptive responses honed by millions of years of evolution.

And your personal experience of your children recovering faster is supported by peer-reviewed data. Administering antipyretics to children likely prolongs their infections:

NOT administering antipyretics to covid patients probably could have saved a lot of lives, too. Because lowering fever causes cutaneous vasodilation and lowering of blood pressure. What this then leads to is medical staff giving covid patients fluids to raise their blood pressure, which turns the patients into big bags of water and fills the lungs, which then results in patients being put on ventilators.

Offering so much much “supportive care” is far worse than doing nothing and letting the body do what it was evolutionarily designed to do. We are the only warm-blooded species that attempts to lower its fever and do all this other nonsense with hydration and feeding when sick.
