Weaning from breastmilk generally does not require the evacuation of residual milk, but it is necessary to evacuate residual milk if there is mastitis caused by residual milk, or if there is unbearable pain due to excessive accumulation of milk in the mammary glands.
If, during the weaning process, the mammary glands need to be emptied in time due to mastitis caused by residual milk, or if the pain is unbearable due to excessive milk stagnation in the mammary glands, which interferes with normal life and work, it is necessary to express or discharge a small portion of the residual milk with a breast pump.
Since repeated milking and repeated nipple stimulation during the process of breastfeeding will reflexively cause an increase in lactogen secretion, leading to prolongation of the breastfeeding cycle and failure of breastfeeding cessation, residual milk does not need to be discharged under normal circumstances.
Normally there is no need to express residual milk. If there are other discomforts in the process of breastfeeding, you should consult a doctor in time to find out the cause and treat the cause.
