yes, babies are known to reach a higher temp than adults, they can also take a 40-41 C fever without blinking.
I remember now that my teachers said that tylenol, paracetamols etc would cause the temperature to go down, not only there and then, but over decades when people use it almost daily for pains etc, it gets into our water, system; and we all are affected.
Temperature is what kills cancer cells; no C-cell can survive 39 degrees; they die en masse at that temp.
That is probably why my father in his last hours produces a fever up to 40 C.
The docs try to put the fever down of course. They are docs.
