After the secretion of postpartum prolactin, if the mother does not breastfeed in time, or does not empty her breasts in time, that is, does not discharge milk in time, it is easy to form distended milk. If the milk is distended for a long time, hard lumps may form. In order to prevent this problem, postpartum nutrition is very important, but it is not advisable to make up for it as soon as the child comes out after delivery. The demand for milk from the baby is not much during the first 3 days after delivery, so the mother is not required to promote milk immediately. If the mother does not empty the milk in time, it is easy to form distended milk. If your breasts are swollen and painful, milk should be expressed in time to avoid swelling for a long time, which may lead to inflammation.
