Its mainly due to the estrogen given to her by the mother, caused by a significant drop in estrogen levels after birth. Therefore, it is a physiological phenomenon. First of all, young mothers and fathers should not be anxious or worried because it is a physiological phenomenon that usually lasts for 3-5 days and can be relieved by itself, so no special treatment is needed. If it lasts for a long time, such as longer than 1 week, continue to observe, and if necessary, go to the hospital.
