When breastfeeding is caused by anger, prolactin will have a certain effect on increasing milk secretion. When a woman has negative emotions such as anger or anxiety during breastfeeding, the endocrine system is easily affected, which leads to a decrease in prolactin production, affecting milk secretion and decreasing the amount of milk accordingly. It is possible to stimulate milk secretion and increase the amount of milk by means of lactation. There are many ways to stimulate milk production, such as massaging and unblocking the milk ducts, increasing the number of times the baby suckles, and eating more milk-inducing foods, all of which can promote the secretion of milk. It is recommended that mothers learn to adjust their mindset during breastfeeding and maintain a good mood. If the situation is more serious, you should go to the regular medical institutions for examination and treatment.
