The way, strength and frequency of using a breast pump will have an effect on the amount of milk produced, but as long as the breast pump is used correctly to suckle the milk it will not result in less and less milk being produced. Milk production is a reflexive stimulus, and using a breast pump will stimulate the mammary glands to produce enough milk by simply sucking the milk out completely. Try not to suck only a small amount of milk at a time, as this may lead to less and less milk production if too much is stored in the breast. Try to keep the sucking time at the same period of time. The duration should not be too long and the pressure should not be too much, otherwise the nipples may be easily damaged. Don’t stop in the middle because of the pain, always wait until all the milk in the breast is sucked out before stopping, you can avoid the milk secretion is getting less and less. In daily life, mothers should also pay attention to rest, usually can drink more water, balanced diet, avoid spicy and stimulating food, to ensure the quality of breast milk. If breastfeeding mothers, found abnormalities, it is recommended to seek medical attention in a timely manner, under the guidance of the doctor’s formal treatment.
