any fever in the first months could indicate a significant infection requiring immediate attention. all children under two months old with a true fever need a medical evaluation. call your doctor to check up on fevers for at least the first four to six months of your baby’s life. but fever is only part of the story. an even more important question is: does your newborn look unwell? if your baby appears to be sick in any way - irritability listlessness lethargy poor feeding respiratory distress rash vomiting diarrhoea etc - contact your doctor even if the temperature is not high enough to be called a fever.
should i call the doctor if my baby has a fever?
