Designed to create gentle suction to collect and express milk — relieving full breasts and making sure you never waste a drop. 

The early days of breastfeeding are often marked by uncomfortably full breasts — especially as your supply comes in and your baby gets the hang of their latch. This engorgement can cause pain and discomfort, and even throw your feeding plans off track. (It’s not easy for a baby to nurse, or pump flanges to properly align, when your breasts need relief!)

This is where our new Silicone Wearable Breast Pump comes in. Designed to create gentle, passive suction, it collects and expresses milk without stimulating oversupply — perfect for “taking the edge off” in-between feedings, or for wearing when breastfeeding on the other side to catch leaks.  

Read on to learn more about our newest pump, and check out some of our most frequently asked questions.

Key features

Like all of our pumps, the Silicone Wearable Breast Pump is designed to be effective, convenient, and give moms the peace of mind they deserve.

• Holds 3 oz of milk 
• Dishwasher safe with just one part to clean 
• Made of food-grade silicone
• Made without BPA or phthalates 

How the Silicone Wearable Breast Pump works 

Unlike electric pumps, silicone pumps use suction to create an airtight seal around the breast and passively pull out milk. Squeezing the pump (also known as the “bulb”) once you’ve aligned it over your nipple will determine the level of suction — the more you squeeze it, the more intense the suction will be. 

They 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 wear them for the entire length of a feed to catch leaks while nursing or pumping on the other side. 

Will this pump increase my supply? 

While these pumps don’t trigger letdowns, they do express milk — and therefore, they’ll send a message to your body telling you to produce more. Keep this in mind when you’re thinking through how often you want to wear the pump, and for how long. 

Does this pump replace an electric breast pump? 

Since silicone pumps don’t have the stimulation and expression modes necessary to fully empty your breasts, they should not replace an electric wearable or traditional pump. They are meant to be used before, during, or in-between your pumping and feeding sessions to relieve feelings of engorgement — the fact that they collect milk is a bonus, as it can be used to help build your freezer stash! 

How is this pump different from a catch cup?

Both our Silicone Wearable Breast Pump and Catch-All Milk Cup can be worn while nursing or pumping on the other side to catch leaking milk. The difference is that our silicone pump creates gentle suction to express milk, while our catch cup simply collects leaking milk and is meant to be worn in-bra between feeding sessions.
