Fever in Children: When Should Parents Consult a Doctor?

Child Health · Last reviewed: August 2026

Fever is one of the most common reasons parents bring a child to the clinic. Fever itself is not an illness. It is a sign that the body is responding to something, most often an infection. Knowing what to watch can help you stay calm and act at the right time.

What is fever?

A body temperature of 100.4 F (38 C) or above is generally considered fever. Use a digital thermometer and note the time and the reading each time you check.

What parents can do at home

• Give small amounts of fluids often, so the child does not become dry.
• Dress the child in light clothing. Do not cover the child heavily.
• Allow the child to rest.
• Write down the temperature readings and the timings.
• Give medicine only in the dose advised by a doctor for your child's weight.

When to consult a doctor

• A baby below 3 months has any fever.
• Fever lasts more than 24 hours despite home care.
• The child is very sleepy, very dull or difficult to wake.
• The child refuses feeds or is passing very little urine.
• Breathing is fast or difficult.
• Fits (convulsions), rash, continuous vomiting or severe pain.
• You feel the child looks unwell even if the temperature is not very high.

Please avoid

• Giving leftover antibiotics or someone else's medicine.
• Changing doses on your own.
• Waiting when the child looks unwell just because the fever came down.
