How Should You Handle First Fever in a Newborn / Infant’s?
September 30, 2025
Introduction
For new parents, nothing feels more alarming than seeing their newborn or infant run a fever. While fevers are common in older children, in babies—especially those under three months—even a slight rise in temperature must be taken seriously. A fever may signal the body is fighting an infection, but in newborns it can escalate quickly. Knowing how to handle it and when to seek expert medical help, such as at Medipoint Hospital, Pune, can make all the difference in your baby’s health.
What Is Considered a Fever in a Newborn?
A newborn or infant is considered to have a fever if their rectal temperature is 100.4°F (38°C) or higher. For babies under three months, any fever above this threshold should be treated as a medical concern.
Normal Baby Temperature Range:
- 97°F (36.1°C) – 99°F (37.2°C) → Normal
- 100.4°F (38°C) and above → Fever
Using a digital thermometer, preferably rectal, gives the most accurate reading in infants.
Common Causes of Fever in Infants
- Viral infections (flu, cold, seasonal viruses)
- Bacterial infections (urinary tract infection, ear infection, pneumonia)
- Reactions after vaccination
- Overheating from excess clothing or high room temperature
Steps to Handle the First Fever in Your Newborn
1. Stay Calm & Confirm the Temperature
Use a digital thermometer to check accurately. Avoid mercury thermometers.
2. Call Your Pediatrician Immediately
For babies under three months, contact your pediatrician right away. Hospitals like Medipoint Hospital, Pune, provide 24×7 pediatric and neonatal care, making them a reliable choice for urgent situations.
3. Keep Baby Comfortable
- Dress in light cotton clothing.
- Maintain moderate room temperature.
- Offer breast milk or formula frequently to prevent dehydration.
4. Avoid Self-Medication
Never give paracetamol or antibiotics without medical guidance. Dosages depend on age and weight.
5. Watch for Emergency Signs
Take your infant to the emergency room if you notice:
- Excessive sleepiness or difficulty waking
- Breathing problems or bluish skin
- Refusal to feed or continuous vomiting
- Seizures or a stiff neck
- Rash with fever
At Medipoint Hospital, pediatric specialists and NICU facilities ensure immediate support in such cases.
When Fever May Be Less Serious
Mild fever after vaccination or slight overheating is common. Still, inform your pediatrician, especially for very young infants.
Preventive Care Tips
- Keep surroundings clean and hygienic.
- Wash hands before handling your baby.
- Limit contact with sick people.
- Stay updated on your baby’s vaccinations at a trusted hospital like Medipoint Hospital, Pune.
