The primary function of the human female breast is to nurse, and it is a mammalian instinct to nurse after giving birth. In itself, it does not require excessive intervention. Forty-eight to 72 hours after giving birth, most new mothers will feel their breasts swelling and painful, as if two large stones were pressed against their chests. This is the beginning of lactation! It is a normal physiological process, do not panic, just let the baby want to eat, do not want to eat with a cold towel to relieve the pain. In a couple of days, the natural swelling and pain will be relieved. The first thing you need to do is to ask someone to press and rub your breasts, which are already edematous. I’ve seen so many unbearable breasts at work, I just can’t stand it anymore. New mothers, your breasts usually belong to the baby, he or she can help you cure small problems; if there is a big problem, find a doctor. Be sure to love your breasts!
