For breastfeeding women who need to artificially express milk from the breast if the baby cannot suckle the nipple normally, they can either express milk directly by hand or use a breast pump to do so. If you are milking by hand, the most correct way is to use the thumb and the belly of the fourth finger in the shape of a C, and slowly squeeze the milk from the bottom of the breast toward the nipple, which can discharge the milk from the breast. It is important not to press at the breast during milking to avoid damaging the breast tissue. If you use a breast pump for milking, it is usually especially convenient to directly use the suction tip of the breast pump to the nipple, and it is best to be close to the entire areola, the milk will be slowly sucked out of the breast, the two sides of the breast completely empty, in order to avoid breast milk stagnation caused by inflammation of the mammary glands, and also to avoid the phenomenon of back to the breast.
