A low-grade fever in a 5-month-old baby is often not very serious, so don’t get too stressed out just yet and pay attention to monitoring your child’s temperature changes. In general, as long as the child’s temperature does not exceed 38.5 ℃, it is not particularly relevant. Do not stop breastfeeding your child at this time, as breast milk is rich in antibodies, which are often very helpful in strengthening your child’s immunity and promoting recovery from the disease, so breastfeeding must not be suspended. In addition, you need to give the child more water, drink fresh fruit juice can also be. If the baby feels uncomfortable, you can use Chinese medicines to reduce fever, such as pediatric antelope horn granules, pediatric black bean curd and clear heat granules or pediatric cold and heat granules. These drugs have a mild antipyretic effect and also have some antiviral effect, which will be better for low fever caused by viral infection. Be sure to let your baby rest more and not overwork, which will help the fever to heal.
