Breastfeeding is not recommended when the fever reaches 38.5 or higher, because it is difficult to keep breastfeeding when there are serious discomfort symptoms, such as dizziness or headache, and it is recommended to actively look for the cause of the fever and treat it with medication according to the cause. If the medication used has an impact on the quality of breast milk, it is recommended to artificially feed during the medication period, drink more hot water and eat lighter foods to help the body recover as soon as possible.
