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 is especially helpful for those returning to work or needing to be away from their baby. Using a breast pump can help maintain milk supply and provide flexibility in feeding. Many mothers choose to pump to share feeding responsibilities with partners or caregivers. Breast pumps come in various styles and sizes, catering to different needs and preferences, making them a valuable tool for breastfeeding mothers.
