The mother can continue breastfeeding because the cold virus is mainly spread through droplets. If the mother has a mild cold and does not take any medication, she can wear a mask and continue breastfeeding. If the cold is serious, the mother can take herbal medicine for cold, such as Shuanghuanglian Oral Liquid, Banlangen Granules, Anti-viral Oral Liquid, etc. At this time, the mother can wear a mask while breastfeeding. If there is a high fever, it is recommended to stop breastfeeding 1-2 days after the high fever and to express the milk. If the mother takes western medicine, she should breastfeed more than 6 hours after taking the medicine. In general, breastfeeding can still be continued because colds are transmitted through the respiratory tract, not through breast milk, but it is best for the mother to wear a mask when breastfeeding and caring for the baby to avoid transmitting it to the baby. If the baby has cold symptoms, it is also safer for the mother to take the above medication and give it to the baby through her breast milk than for the baby to take the medication directly.
