If the mother has symptoms of a cold during the breastfeeding period, it is important to note that minor symptoms such as slight sneezing and runny nose do not affect breast milk, as this is just a common cold, which typically resolves on its own within about seven days. During this period, it is recommended to drink more water to promote excretion and enhance the body's resistance. If the symptoms are more severe, it is possible to take some anti-inflammatory and anti-infection traditional Chinese medicine or cold-relief traditional Chinese medicine under the guidance of a doctor. It is crucial to maintain a relaxed mood without too much stress, avoid staying up late, ensure sufficient sleep, and enhance the body's resistance. Additionally, it's important to frequently ventilate the room to keep the air fresh and maintain appropriate temperature and humidity. Avoid close contact with the baby and wear a mask while breastfeeding.
