Temperature thresholds by age, safe dosing, hydration signals, and the four symptoms that justify calling a doctor immediately.
Fever is the single most common reason parents call a doctor at night, and the single most over-treated symptom in childhood. It helps to start from the right premise: fever is not the illness. It is the immune system working, and the number on the thermometer is a poor guide to how serious the underlying cause is.
A child with 39.5°C who is drinking, playing between naps and making eye contact is usually less worrying than a child with 38.2°C who is limp and refusing all fluids. Treat the child, not the number.
Age changes everything
- Under 3 months, any temperature of 38°C or above: seek medical assessment immediately, whatever the child looks like. Newborn immune systems give very little warning.
- 3 to 6 months, 39°C or above: get same-day assessment.
- Over 6 months: how the child is behaving matters more than the reading.
Measuring it properly
Under three months, an armpit digital thermometer is the practical choice. From three months onward, ear thermometers are fine if positioned correctly. Forehead strips and most no-contact scanners are the least reliable — if the reading surprises you, confirm it another way before acting.
Medication, honestly
The purpose of paracetamol or ibuprofen is comfort, not normalising the number. If a child is comfortable at 38.8°C, medicating is optional. If they are miserable at 38.2°C, treating is reasonable.
- Dose by weight, not by age. Age brackets on packaging are averages and can substantially under- or over-dose a given child.
- Never exceed the stated daily maximum, and write down each dose and time. On a broken night, two adults each giving a dose independently is a real and common accident.
- Ibuprofen needs food or milk in the stomach, and should be avoided in dehydration or chickenpox.
- Aspirin is not for children.
- Alternating both medicines is sometimes advised by a doctor for a specific child. Do not improvise it — that is how double dosing happens.
Hydration is the real priority
In a Dubai summer a feverish child loses fluid faster than parents expect, particularly moving between cooled indoor air and outdoor heat. Small volumes offered very frequently work far better than encouraging a large drink: a syringe or spoon every few minutes if needed. Oral rehydration solution beats juice, which can worsen diarrhoea.
Wet nappies are the most reliable home measure. Fewer than four in twenty-four hours in a small child, or no urine for eight hours in an older one, means seek help. Dry lips, no tears when crying, or a sunken soft spot on a baby’s head are later and more urgent signs.
What not to do
- Do not cold-sponge or use ice baths. It causes shivering, which raises core temperature.
- Do not wrap a feverish child in blankets to sweat it out.
- Do not ask for antibiotics for a viral illness. They do nothing for the virus and cause side effects.
- Do not chase the thermometer every fifteen minutes. It raises everyone’s anxiety without changing the plan.
When a home visit makes sense
A feverish child who is drinking and reasonably alert, but has had symptoms for two or three days, needs an examination — ears, throat, chest, abdomen — and possibly a rapid test. That is exactly the assessment a home doctor can complete in one visit, without a waiting room full of other viruses and without waking a sleeping child for a car journey.
The patients who benefit most from home care are rarely the sickest. They are the ones for whom leaving the house is the barrier to being seen at all.
