The Willow Silicone Wearable Breast Pump is designed to create consistent passive suction, our new pump can be worn to gently induce letdown and relieve discomfort. Pump can be worn for a few minutes to quickly relieve pressure before pumping or feeding, or in-between feeding sessions if your baby isn't ready to nurse. You can also use it for the entire length of a feed to catch leaks while nursing or pumping on the other side.
