A breast pump is a device used by nursing mothers to extract milk from their breasts. It can be manual or electric, allowing mothers to store milk for later use, which can be helpful for returning to work or managing feeding schedules. Breast pumps come with various attachments and features, such as different suction levels and sizes of breast shields, to accommodate individual needs. Many mothers use them to maintain milk supply or to relieve discomfort caused by engorgement. Proper cleaning and storage of the extracted milk are essential for safety and hygiene.
