What is the normal temperature for a 4 month old?

The normal body temperature for a 4-month-old infant typically ranges from 97°F to 100.4°F (36.1°C to 38°C) when measured rectally. A temperature above 100.4°F (38°C) may indicate a fever, which could require medical attention. It's important to consult a pediatrician if you have concerns about your child's temperature or overall health.
