For breastfeeding mothers, pumps are essential because they allow you to express your breast milk when you are away from the baby so that you don’t experience pain or engorgement. There are two different types of breast pumps: electric and manual. They each have their own benefits, but having a manual breast pump on hand is always helpful for unexpected situations.

Before heading out to buy a manual pump, research options that are ideal for your breast size to ensure that each pumping session is comfortable and efficient. Also, consider when you’ll be using your manual pump. If you plan on keeping it in your diaper bag or work purse, a compact option would be ideal.

Since it can be tricky to decipher what specific pump is best, we’ve rounded up some of the best options on the market to help you out.
