Insufficient milk secretion eight days after cesarean section may be due to insufficient water in the mother’s body or lactation feedback has not been established, which may allow the mother to adjust her diet and also allow the baby to suckle effectively. 1. Adjust the diet: after the birth of the mother, if the body is not enough water, it is easy to lead to a decrease in the amount of milk secretion. At this time, you can let the mother eat more water-rich and nutrient-rich food, such as chicken soup, carp soup, etc., and also add some fresh vegetables and fruits as appropriate. 2. Effective sucking: After eight days of cesarean section, if the baby sucks insufficiently, it will affect the establishment of normal lactation feedback. You can increase the number of times the baby sucks on the breast and adopt the correct sucking posture. In addition, breast massage can be performed by a medical professional to promote milk production. If breast milk secretion does not increase even after positive dietary adjustments and allowing the baby to suckle more often, you can go to the hospital for consultation to identify the cause of insufficient milk secretion and then take targeted treatment.
