What is the normal temperature range for a newborn?

• A. 95.0 F to 97.0 F
• B. 98.0 F to 99.5 F
• C. 99.0 F to 101.0 F
• D. 97.7 F to 99.5 F

Answer: (D)

Newborns have immature temperature regulation, so their normal baseline sits a bit lower and can vary more than in older children and adults. The typical, safe reading for a newborn is usually taken under the arm (axillary), since that method is practical and appropriate for neonates. A normal axillary range is about 97.7°F to 99.5°F (36.5°C to 37.5°C). Understanding the numbers helps: temperatures at or above about 100.4°F (38.0°C) in a newborn are considered a fever and warrant evaluation, while temperatures below around 97.7°F (36.5°C) raise concerns for hypothermia. So the listed range of 97.7°F to 99.5°F represents a typical normal neonatal temperature.
