Maternity does not affect breastfeeding if it is just a common cold. During breastfeeding, there is no increased risk of infection to the baby through breastfeeding. Colds are transmitted through the upper respiratory tract, so if the mother has a cold, it is recommended to wear a mask while breastfeeding so that the discharge of bacteria can be reduced. Mothers should wash their hands before breastfeeding, as hand hygiene can also inhibit the reproduction of viruses. Under normal circumstances, common colds and gastrointestinal illnesses will not affect breastfeeding. Only if the mother has a serious inflammation of the mammary glands will she need to suspend breastfeeding, but otherwise she should breastfeed on demand. The only way to get more and more milk is to let the baby suckle constantly.
