The silicone pump holds 3 oz of breast milk.

The pump uses passive suction to gently express and collect leaking milk. They do not have stimulation or expression modes like an electric pump, so they will not fully empty your breasts.

The more you squeeze the front of the pump (aka the “bulb”), the stronger the suction will be.

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

The pump is made of food-grade silicone without BPA or phthalates.

Like most of our pump parts, the silicone pump is dishwasher safe on the top rack and can also be washed in warm, soapy water.
