Fever: What Actually Matters (and What Doesn't)
The number on the thermometer is the least useful thing about a fever.

Fever is a response, not a disease. What we watch is the child - how they drink, how they breathe, how they look between temperature spikes.
Why the number misleads
A high temperature does not reliably indicate a serious infection, and a modest one does not rule it out. What clinicians actually assess is the whole child: alertness, colour, breathing, hydration, and how they behave once the temperature comes down.
“Treat the child, not the thermometer.”
What to do at home
Offer fluids often and in small amounts. Dress lightly. Use paracetamol or ibuprofen for comfort at the dose your pharmacist or physician has given for your child's weight - for comfort, not to chase a number. Rest is the treatment; the fever is the sign.
