What the best breast pumps have

  • Different sized flanges. Women's breasts can vary widely in size. Most breast pumps come with a medium-sized flange. If you have larger or smaller breasts or nipples, be sure you can purchase larger or smaller flanges. This is important both for comfort and for proper flow.
  • Letdown stimulator. Some moms need a pump that can stimulate their letdown reflex so their milk can flow. This is vital for women who want to feed their baby breast milk but haven't yet nursed their child due to circumstances that kept them from doing so.
  • Several power options. Breast pumps that have a battery pack allow you to take them to work or walk around the house while pumping. They are also a must if you have to pump in an area with no power outlets.
  • A hands-free option. Moms overwhelmingly say they love being able to surf the Internet, care for their children, read a book or fold clothes while they pump. Most pumps are compatible with a variety of generic hands-free bras.

Know before you go

Does pumping hurt? If it does, consult your doctor, a lactation expert or the pump manufacturer for assistance.

How often will you be pumping? A stay-at-home mom who exclusively breastfeeds her baby will probably be fine with a manual or single electric breast pump. A working mom or mom who pumps exclusively will be better served with a double electric.

What are your storage/transport needs? A stay-at-home mom may be able to get by with a couple of bottles and a bare-bones unit that includes just the pump. A working mom, or one who travels, needs options to tote the breast pump components and store the breast milk at a safe temperature.

Where do you buy parts and accessories? One reason Medela pumps are so highly rated is because components can often be found at the supermarket or drug store. Other breast pump manufacturers sell parts only at dedicated retailers or online. Be sure you know where and how to find replacement parts if needed.

Should you buy a used pump? No. The chance of cross-contamination with bacteria or viruses with personal-use breast pumps is high. Even if you purchase new tubing, flanges and other parts, the motor can contain microscopic bacteria that can seriously harm your baby. Only rented hospital-grade pumps are suitable for sharing.
