When buying a breast pump, you'll want to look at how to keep it clean, personal comfort and your day-to-day lifestyle. If you'd prefer not to plug it into an electrical outlet or you're after a budget-friendly option, go for a manual breast pump that lets you take control of your feeding and pumping process. If you're expressing regularly, an electric breast pump might be a little easier. These models are super-efficient and often save you time, as the motor does all the pumping for you.
