Many women find it convenient, or even necessary, to use a breast pump to express and store their milk when they have resumed work, are traveling or separated from their baby in any way. They are often happy to learn that a breast pump can be used as a breastfeeding supplement and that some are designed to mimic a baby's sucking at the breast. Breast pumps are designed to be used by nursing women in the hospital or to express breast milk at home. They help relieve congestion symptoms by expressing milk. In case of mastitis, breast pumps facilitate the healing process by drawing breast milk from the inflamed breast. Breast pumps relieve sore, cracked nipples and make flat or umbilical nipples stand out. They also allow mothers to give their breast milk to babies who cannot feed directly from the breast for various reasons, such as breastfeeding problems, cleft palate, or prematurity.
