Frequently Asked Questions
What is a normal baby temperature?
Normal temperature ranges from 36.5–37.5 °C (97.7–99.5 °F). A fever is defined as ≥ 38.0 °C (100.4 °F) rectally. Armpit measurements run about 0.5 °C lower, so add 0.5 to compare.
When should I call the doctor about my baby's fever?
Call immediately for any fever in a baby under 3 months. For older babies, call if fever exceeds 39.0 °C, lasts more than 3 days, is accompanied by a stiff neck, rash, breathing difficulty, or if your baby seems very unwell.
Can teething cause a fever?
Teething may cause a slight temperature rise (up to 37.8 °C) due to gum inflammation, but it does not cause a true fever (≥ 38 °C). A baby with teething AND a real fever likely has a separate illness.
Why does my baby get a fever after vaccines?
Vaccines trigger an immune response, which can cause a low-grade fever of 37.5–38.5 °C for 1–3 days. This is expected and normal. A fever over 39 °C post-vaccine or fever lasting more than 3 days warrants a call to your doctor.
How should I track my baby's temperature?
Log each temperature reading in BabySync with the time, measurement method, and a note (normal/low fever/high fever/post-vaccine/after bath). Ask ChatGPT "Show me this week's temperature trend" to see if fever is rising or falling.
