If a 6-month-old baby has a fever, if the mental state is relatively good and the stools and urine are normal, you can give the child more water, take vitamin C supplements, pay attention to rest, prevent cross-infection with other babies and be alert to the phenomenon of convulsions caused by high fever. You can wipe your child’s forehead, armpits and groin with warm water to treat headache, fever, nasal congestion, sneezing, runny nose and other symptoms caused by cold. If the body temperature exceeds 38.5℃, you can take oral ibuprofen suspension drops, which are mainly used to reduce fever in infants and children. If the child is depressed and the fever persists, accompanied by coughing symptoms, consider pneumonia caused by upper respiratory tract infection, and it is recommended to consult the pediatrician.
