What is a good temperature for infant?

A normal temperature for an infant is from 97.4-99.4. If an infant's temperature is above 100.4, and the infant is under 6 weeks old; they need to be seen by a health care providor. If a doctor has already told you that you can give Tylenol or Motrin, give that first to see if it brings the temperature down. If it remains above 100.4, you need to bring them in to be seen.
