If you’re a breastfeeding mom who pumps, you know it can be a challenge to keep up a good milk supply. The Willow Generation 3 Smart Breast Pump promises to help you pump 20 percent more milk per session. It also includes sensitivity and suction settings. What’s more, this breast pump—like its predecessors—comes in the form of two wearable battery-operated cups. So you won’t have to stay next to an electrical outlet during pumping sessions. Finally, the pump pairs with an app that tracks your milk volume over time. It will help you can see how much you’ve pumped across sessions. Best of all the Willow Generation 3 is quiet and so leak-proof, you could use it while doing yoga.
