Fever in children: when to watch at home and when to see a doctor

Fever in children: when to watch at home and when to see a doctor

Quick answer

Fever is a normal response of a child's body to an infection, not an illness itself. At home, keep your child hydrated and lightly dressed. Seek medical care if they are under 3 months old, if the fever is very high or lasts more than 3 days, or if you see signs like trouble breathing, skin spots, extreme lethargy, or seizures. AVA Médica offers walk-in care 7 days a week.

Few things worry a parent more than a child who feels hot with fever. The first helpful thing to know is that fever is not an illness: it's how a child's body fights an infection. In most cases it passes and can be managed at home.

What counts as a fever?

A fever is a body temperature above 38 °C (100.4 °F). Between 37.5 and 38 °C it's considered a slightly raised temperature. More than the exact number, watch how the child is doing: their mood, color, and whether they're drinking fluids.

What you can do at home

  • Offer fluids often to keep them hydrated.
  • Dress them lightly and keep the room cool; avoid over-bundling.
  • Let them rest; the body recovers better at rest.
  • Any fever medicine should be given only as directed by a doctor and at the right dose for their weight.

Warning signs: seek medical care if…

  • The baby is under 3 months old and has a fever.
  • The fever is very high or lasts more than 3 days.
  • They have trouble breathing or are breathing very fast.
  • Skin spots appear that don't fade when pressed.
  • They are very lethargic, irritable, not responding as usual, or refusing fluids.
  • They have a seizure.

With any of these signs, the safest step is to have a doctor evaluate the child as soon as possible.
