During the 9-11 months of breastfeeding, the amount of breast milk secretion and the nutrients in the milk are slowly decreasing, while the baby’s sucking needs are also decreasing and the amount of complementary foods for the baby is gradually increasing, at this time the mother can consider weaning. Generally, breastfeeding can be gradually reduced and complementary foods can be added to ensure that the baby has the necessary nutrients for normal development. As the baby sucks less, the mother’s lactogen secretion decreases, and the milk will slowly go from being produced in large quantities to being stopped. However, if the mother has more milk on a regular basis or the baby is more dependent on breast milk, it may take longer to return to breast milk. If you want to wean quickly and without pain, you need to take medications that reduce milk production, for example, consider taking estrogen, and vitamin B12 to promote milk return. It is recommended that the mother take raw malt in water for 3-4 days before weaning for frequent use. In case of milk increase, you can also use mangosteen to seal the package with local hot compresses, or consume malt, pepper, barley tea or leek to promote milk return. During the weaning period, the mother should try to eat a light diet, not to eat high-protein food, and to drink as little water as possible. Weaning is a gradual process, so the mother should not be too impatient, but keep a good attitude and relaxed mood in order to facilitate the return of milk after childbirth.
