Fever is one of the most common signs that something might be wrong with your child’s health—but what exactly is a fever, and when should you be concerned?

Let us break it down in a simple, practical way.

🌡️ What Is a Fever?

Fever is an increase in body temperature beyond the normal range. But here is something many parents do not realize:

“Normal” body temperature is not the same for everyone.

It can vary depending on your child’s age, the time of day, and how you take the temperature.

✅ What Is a Normal Body Temperature?

Humans are generally born with a core temperature of about 36.5°C. As children grow, their body temperature may fluctuate slightly due to activity, sleep, and environment.

It is critical to understand the measurement method, as different methods have different “normal” ranges.

Determining Fever

🔍 Ways to Measure Temperature in Children

Here are the most common ways to take a child’s temperature, with guidance on when to use each method:

  1. Rectal (in the bottom)
  • Most accurate, especially for babies and toddlers.
  • ✅ Recommended for birth to 5 years.
  1. Axillary (under the armpit)
  • Easy and non-invasive.
  • ✅ Suitable for children 3 months and older.
  1. Tympanic (in the ear)
  • Quick and convenient.
  • ✅ Also great for children 3 months and older.
  1. Oral (in the mouth)
  • Recommended for older children who can hold the thermometer correctly.
  • ✅ Recommended for ages 4 years and above.

📈 What Temperature Is Considered a Fever?

The threshold for a fever depends on the method used and the child’s age. Here is a quick guide:

Armpit (Axillary) Temperature

  • Fever is above 37°C
  • For children aged 0 to 2 years, fever is above 37.5°C

Ear (Tympanic) Temperature

  • Fever is above 37.8°C
  • For neonates (0 to 28 days) and infants (28 days to 24 months), fever is above 37.85°C

Knowing these numbers can help you decide when to offer comfort or seek medical advice.
