Your baby feels hot. You take their temperature and it reads 38.5 degrees. Your heart rate doubles. This guide is designed to give you a clear, calm framework for managing baby fever in India.
What Is a Fever?
A fever is a body temperature above 38 degrees Celsius (100.4 Fahrenheit). Fever is not the illness — it is the immune system's response to illness. A moderate fever actually helps the body fight infection by creating an inhospitable environment for bacteria and viruses. The discomfort of fever, not the fever itself, is what we treat.
How to Take a Baby's Temperature Accurately
The most accurate methods: rectal temperature (gold standard for babies under 3 months), underarm (axillary) temperature with a digital thermometer (add 0.5 degrees to get approximate core temperature), and ear (tympanic) thermometers are convenient but can be inaccurate in young babies. Forehead strip thermometers are the least reliable. For any baby under 3 months, always confirm with a proper thermometer.
When Fever Needs Immediate Medical Attention
Any fever in a baby under 3 months — go to hospital immediately, do not wait. Any fever above 40 degrees in any age baby. Fever lasting more than 5 days. Fever with rash, stiff neck, extreme headache, persistent vomiting, difficulty breathing, or seizures. A baby who is extremely difficult to wake, unusually limp, or inconsolable. Signs of dehydration — no wet nappies, dry mouth, sunken soft spot. Your instinct that something is very wrong.
Home Care for Fever
Dress your baby lightly — one thin cotton layer. Do not bundle them in blankets, which traps heat. Keep the room comfortably cool (24 to 26 degrees). Offer frequent milk feeds — breast milk or formula contains antibodies and provides hydration. For babies over 6 months, offer cooled boiled water frequently. A lukewarm (not cold) sponge bath can provide relief — wipe the forehead, neck, armpits, and wrists with a damp cloth.
Medicines for Baby Fever
Paracetamol (Calpol syrup) is safe from 2 months and above, in the correct weight-based dose. Check the dosing chart on the packaging or ask your pharmacist. Ibuprofen (Brufen) is safe from 6 months. Never give aspirin to children under 16. Alternate paracetamol and ibuprofen if fever is not responding — discuss with your paediatrician.
Febrile Seizures
Febrile seizures (fever-triggered convulsions) affect about 2 to 5 percent of children between 6 months and 5 years. They are frightening but rarely dangerous. If your baby has a seizure: lay them on their side, time the seizure, do not put anything in their mouth, stay calm. After the seizure, take them to hospital. Most febrile seizures last less than 2 minutes and do not cause brain damage.
