Lack of milk after delivery is a relatively common phenomenon among breastfeeding women and is associated with a variety of factors such as poor lactation ducts, late suckling by the newborn, emotional factors, nutritional deficiencies and poor congenital breast conditions. The effect is affected by different factors and there are some differences. A, lactation has a role: 1, mammary duct is not smooth: can lead to blocked milk discharge, through the way massage can unblock the mammary duct, improve lactation is not smooth; 2, newborn sucking too late: maternal postpartum did not let the newborn suck the breast as early as possible, resulting in too little milk secretion, through massage lactation auxiliary fetal sucking way to stimulate the breast, can increase milk secretion; 3, emotional factors: maternal mood is poor, resulting in The effect of massage treatment is better, if necessary, together with lactation and liver regulating drugs for treatment, the effect is better. Second, the effect of lactation is not obvious: 1, nutritional deficiencies: the maternal own intake of nutrients, resulting in too little milk, massage lactation can not increase milk secretion; 2, poor congenital conditions of the breast: poor congenital development of the breast, limited mammary gland function, insufficient milk secretion function, resulting in too little milk, the general lactation effect is poor.
