The main reasons for this are: 1. If the symptoms of maternal cold are mild, it is possible to continue breastfeeding and it will not infect the baby. It is recommended that the mother put on a mask when breastfeeding her baby to prevent the cold from being transmitted to the baby. 2. If the symptoms of maternal cold are serious and accompanied by high fever, it is not recommended to continue breastfeeding because the symptoms of maternal high fever prove that the bacteria in the body is serious and may be transmitted to the baby. It is also not recommended to continue breastfeeding if the mother is infected with the flu virus, because the flu is more contagious and there is a possibility that the virus will be transmitted to the baby during the breastfeeding process.
