Whether you need to express milk during breastfeeding depends on the severity of breast swelling and pain during breastfeeding. If the milk secretion decreases significantly after taking Milk Support and there are no obvious symptoms of breast swelling and pain and milk stagnation during the process of breastfeeding, milking can be dispensed with. If the milk secretion does not decrease significantly after taking Milk Support, and the symptoms of breast swelling and pain and milk stagnation are serious, you should consider expressing too much milk to relieve the symptoms of breast swelling and pain so as not to cause inflammation of the breast. During the weaning period, you also need to pay attention to control your diet and not to eat fish soup, chicken soup, mutton soup and other foods with lactation effect.
