What is the Normal Body Temperature for a Newborn Baby?

The arrival of a new baby brings immense joy to parents. However, amidst this happiness, it is crucial to closely monitor the baby's physical changes. Newborns have a relatively low immune system, and any slight negligence can lead to colds or even fever. Therefore, regular temperature checks are essential. Let's discuss what constitutes a normal temperature for newborns.

1. What is Considered a Normal Baby Temperature?

A newborn's body temperature cannot be directly compared to an adult's as it tends to be slightly higher. During spring, autumn, and winter, a baby's axillary temperature varies between 36.6°C in the morning and 36.9°C in the afternoon. In summer, it may be slightly higher, with morning temperatures around 36.9°C and afternoon temperatures around 37°C. It's important to note that a slightly elevated temperature without any other symptoms does not necessarily indicate fever. Accurate diagnosis requires considering the overall situation.

2. What Temperature Constitutes a Fever in Babies?

A normal axillary temperature for infants ranges from 36°C to 37°C. If the temperature exceeds 37.4°C, it is considered a fever. Infant temperatures can fluctuate, but anything above 37°C is considered a fever. Fevers are further classified as low-grade (37.5°C-38.4°C) or high-grade (over 38.5°C). However, it's crucial to consider each baby's unique physical condition and constitution.

3. Normal Temperature Ranges for Oral, Axillary, and Rectal Measurements

There is a 0.5°C difference between rectal, oral, and axillary temperatures, with rectal temperature being the highest. Normal axillary temperature ranges from 36°C to 37°C. For rectal temperature, the normal range is 36.5°C to 37.5°C, and for oral temperature, it is 37.5°C. Many new parents may feel nervous when measuring their baby's temperature due to lack of experience, but it's essential to remain calm and follow proper procedures.
