The best time for postpartum lactation is generally the third day after delivery, but the exact time varies from person to person. Postpartum lactation mainly includes sucking stimulation, massage, hot compress and food therapy. In general, breastfeeding can be started within 1 hour after delivery. Through the baby’s sucking, the secretion of prolactin and oxytocin can be stimulated, which helps the formation of milk, and the more the sucking stimulation, the more the amount of milk will be. Within 24 hours to 3 days after delivery, you can apply hot compresses and massage to your breasts to improve the blood circulation of your breasts, which will help to smooth the milk ducts, promote the intake of nutrients and lactation, and reduce the chance of mastitis, generally once a day. In addition, it is not suitable for women to eat lactation food as their spleen and stomach functions have not fully recovered within a short period of time after delivery. Usually on the 4th day after delivery, you can start to consume moderate amount of lactation food, such as crucian carp soup, pig’s feet soup, etc. In conclusion, postpartum lactation is recommended to be performed correctly and reasonably under the guidance of a professional doctor to ensure safety.
