Take milk to work. At this time, in fact, the mother’s lactation situation is relatively stable, and she can adapt to the breast pump better. When the mother first uses the breast pump, don’t mind the output too much. The breast must adapt to a new lactation stimulation. If it takes time, do not increase the intensity of breast pumping and extend the time of use because of unsatisfactory yield. This will not significantly increase the milk volume and may cause breast injury.
