Do not breastfeed again after taking breastfeeding pills because most breastfeeding pills, especially those used by Western medicine, are estrogens, such as hexestrol, which can enter the child’s body through breast milk and thus affect the child’s own hormone secretion, thus producing adverse effects. Some of the breastfeeding pills are herbal ingredients, and even if they are herbal ingredients, they may still enter the child’s body through the breast milk and have a negative effect on the child. Under normal circumstances, it is necessary to minimize the use of breastfeeding medication because the secretion of milk is characterized by more frequent breastfeeding, the more milk is produced, and after stopping breastfeeding, the milk will gradually decrease or even be absent. By reducing the number and amount of feedings, the milk secretion will gradually decrease and the milk will be returned to the breast at this time, not necessarily through drug intervention.
