How to choose the appropriate breast pumping strength?When using a breast pump, harder is not always better. When the intensity of sucking milk is at the first level and you feel it is not strong enough, you can increase it to the second level. When you reach the second gear, you still feel that it is not strong enough, but when you increase it to the third gear, you experience pain in your breasts and nipples. This means that the strength of the third gear is too strong for you, and the second gear is more suitable.2. What should I do when my breasts are blocked or my breasts are blocked?When milk blockage or mammary gland obstruction occurs, gently massage the areola, express milk with your hands to drain the milk from the areola, and then use a breast pump to express milk when the areola is soft.3. Breast leakage problemSome people think that using a breast pump will make the nipple holes enlarge and leak milk. In fact, it does not. Sucking one breast will make the brain connect.When stimulated, the mammary glands secrete prolactin to secrete milk. This stimulation is the same for both breasts, so milk will drip from the other side, commonly known as milk leakage. This is a normal phenomenon. Direct breastfeeding can also cause this situation. Using a breast pump can make preparations in advance to avoid the milk from the other side getting the baby's clothes wet. Sometimes, even if you are breastfeeding directly, your nipples may be stimulated by external stimuli (such as friction and contact with clothing, etc.) and cause lactation. Of course, this varies from person to person.
