How to Use the Baby Fever Guide
Enter the temperature, choose Celsius or Fahrenheit and enter the age, then press Check Temperature. The tool grades it and suggests the next step.
Reading the result
A fever is generally a temperature of 38 C (100.4 F) or more.
Any fever in a baby under 3 months needs urgent medical review.
A very high fever of 40 C (104 F) or more needs prompt care.
How your baby looks and behaves matters as much as the number.
