If an 8-month-old child has a fever of 38℃, if he or she is in a relatively good state of mind, eats well and has normal bowel movements, he or she needs to drink more water, take rest and take vitamin C supplements to prevent cross-infection, and be alert to dehydration and convulsions caused by high fever. If the body temperature exceeds 38.5℃, acetaminophen suspension can be used for symptomatic treatment, which can quickly reduce fever. If the body temperature continues to rise, or is accompanied by poor mental health, irritability, low urination and other reactions, promptly go to the hospital and improve the relevant examination to avoid delaying the condition.
