Most breastfeeding mothers do not need a pump at all. If you decide to get a pump, most lactation experts agree that a double expression breast pump is ideal, though a single expression pump can be beneficial in certain scenarios, such as when nursing and pumping at the same time.
You can also choose between manual and electric breast pumps, which comes down to preference.
If you have a low milk supply, need to build up stores, or establish your milk supply, a hospital-grade breast pump is a good choice. If your baby spends time in the NICU or is born prematurely, your doctor may recommend one. In most cases, a double electric pump will fulfill pumping needs.
