When a child has a seasonal fever, they often do not tell you because even they cannot understand what their body is going through. However, they will definitely show their discomfort.

As the best pediatricians in Kolkata often say, discomfort will reflect through their behavior, not words. As a parent or caretaker, you must watch for unusual tiredness, constant irritability, not wanting to drink fluids, or even breathing difficulty. These small behavioral changes are your child’s silent signals for help. 

Trust your instincts and if something feels off, don’t wait; visit a child’s fever clinic near you, like IRIS Multispeciality in Kolkata. Early care can help bring comfort and peace of mind to your child.

How to Measure Your Baby’s Temperature for Fever

Here is the best methods by age 

A. Birth to 3 Months

  • Rectal is best. 
  • Forehead (temporal) can be used for initial screening; however, a child’s fever doctor in Kolkata may want a rectal confirmation.

B. 3 Months to 4 Years

  • Rectal, temporal artery, or axillary (armpit) are good.
  • Wait 6 months for the ear (tympanic).

C. 4 Years and Older

  • Oral (mouth) is best if they can cooperate.
  • You can use rectal, ear, or armpit.

How to Take the Temperature

Rectal (most accurate for infants under 3 months)

Clean and lubricate the tip with petroleum jelly. Then gently insert a little (½ to 1 inch into the anus), and wait for the beep.

Armpit (axillary, less accurate)

Wipe the armpit dry, then place the thermometer in a dry armpit, and hold for 4-5 minutes or wait for the beep.

Ear (tympanic, for ages 6 months+)

Gently pull the ear back and up, then insert the thermometer, and press the button.

Note: Avoid if earwax buildup is present. Always remember, ear temperatures are not considered accurate for babies younger than 6 months.

Forehead (temporal artery scanner)

Turn on the device; remove hair from the forehead, then slowly slide the scanner across the forehead. Ensure no sweat and hair interference.

Note: Always follow manufacturer's instructions. Always use digital thermometers; never glass or mercury.

What Temperature Counts as a Fever in a Child?

Best pediatric hospital in Kolkata​ says here are the temperatures that can indicate fever in babies:

Forehead (temporal) 100.4°F (38°C) or higher

What are the Possible Reasons for a Fever in a Child?

Fever generally means that their body is fighting an infection but it can also happen from post-vaccination or teething (mild temp).

However, always consult a child fever clinic like IRIS Multispeciality in Kolkata for the accurate diagnosis and treatment.

Here are some possible reasons:

1. Infections From Virus

  • Colds
  • Flu
  • Roseola, also known as sixth disease (because it was the sixth common childhood rash), affects most babies and children before they turn 2.
  • Hand, foot, and mouth disease
  • Chickenpox

2. Infections from Bacteria

  • Ear infections
  • Strep throat
  • Urinary tract infections (UTIs)
  • Pneumonia
  • Sinus infections

3. Post-Vaccination

  • A mild fever can happen after immunizations. This indicates their immune system is responding in a healthy manner and building protection against possible future infection. 

4. Teething

  • It doesn't cause a true fever; it leads to a slight rise in temperature.

5. Overheating

  • Too many clothes or a hot season or environment.

6. Less Common Causes

  • Autoimmune diseases or rare chronic conditions.
