A mother with a high fever can breastfeed if her fever has subsided. Generally, a mother with a high fever can breastfeed if her body temperature does not exceed 38℃, but she should drink more water and take antipyretic and cold medicine without side effects to cure the cold as soon as possible so that she can breastfeed her child later and avoid spreading the cold to her child. If the mother has a high fever and the temperature exceeds 38°C, she should not breastfeed her baby because her milk contains a lot of viruses and toxins that are harmful to her child’s health. Therefore, when a mother has a high fever, she should stop breastfeeding temporarily and actively treat the cold, and during the time she stops breastfeeding, she can suck out the milk and breastfeed after the cold is cured.
