    1. Use large pot to prevent parts from touching sides or bottom of pot
  3. Shake off excess water and air-dry on a dedicated rack or clean cloth

*After first sanitizing all parts (except tubing and plastic cups), please do not boil silicone parts again. Do not steam sterilize or dishwash parts at any point. Otherwise, the parts will be damaged and the suction and fit will be affected. Handwash or use UV sterilization or cold water sterilization after first use.


How to single or double pump 

How to assemble

Placement in bra

Ideal bra fit

Correct nipple alignment and a supportive bra that keeps the cups securely in place will ensure your pumping sessions are comfortable and effective.
Double check that you have a good seal between the funnel and your skin.

Positions for expressing 

Disconnecting and storing milk 

  1. Remove your tubing from the cups.
  2. Carefully remove the cups from your bra and place them on a flat, firm surface until you’re ready to transfer your milk.
  3. Tip! When pouring your milk, use your thumb to squeeze the breast shield to control flow.

Issue Solution
Condensation in tubing Ensure the tubing, the silicone membranes, and membrane caps are dry before use. If condensation occurs, ensure tubing is dry before next use: Disconnect the tubing from cups and turn the pump back on to dry the tubing while you are storing your breastmilk
Milk in tubing Check the membranes for damage. Replace the membranes if needed and clean/replace the tubing.
Low or no suction Make sure your pump is turned on and the suction level is set properly. Check duckbill valves for any damage or wear. Replace valves if needed. Confirm that duckbill valves are oriented in the correct position; see assembly instructions on page 9 for guidance. Check that all parts are dry and securely assembled, especially tubing Adapter A and/or B. Check tubing to ensure it is inserted into the backflow protector ports firmly with appropriate adapter(s). If using as a single pump, check that the disconnected side of the tubing is firmly inserted into the top of the Y-shape connector. Keep collection cups with adapter and tubing perpendicular and upright in bra; see page 10 for placement and bra fit instructions.
Air escaping or whistling Some audible air is normal as air movement is part of suction control. Review “Connecting to a Compatible Pump” on page 13 and 14 to ensure that the appropriate adapters are inserted into the tubing. Wedge Adapter A as far down as possible into the backflow protector port BEFORE you put the pump parts into the cups.
Backflow Protector/ Membrane Cap opening/clicking Separate silicone membrane from membrane cap and backflow protector and ensure that all parts are clean and dry. Examine membrane for damage or warping and replace as needed. Reattach the membrane to the backflow protector and confirm that seal is tight before closing with membrane cap
Nipple Pain or Discomfort Seek advice from a Lactation Consultant as comfort can be key to sustaining a breastfeeding journey. Ensure you are using well-fitted breast shields for both breasts; see page 16 for Troubleshooting Breast Shield Size. Sometimes with wearable cups, we have to size down for added comfort and improved milk output. Lubricate breast shields with a thin layer of coconut oil or Pumping Spray


When It comes to choosing an optimal breast shield, always go by what is most comfortable and effective for you – regardless of how it Looks. Properly fitted breast shields will be 3-4 mm wider than nipples BEFORE pumping and 1-2 mm AFTER pumping, generally speaking. Women with very elastic tissue will often find that the tissue stretches and touches the inside of the breast shield funnel no matter what. If this sounds like you, you may find silicone inserts provide the most comfort because they can physically hold back the elastic tissue.

Pro Tip: The two most important factors in breast shield sizing are that they are comfortable and also maximize your milk output — regardless of what they Look Like.

Pro Tip: Apply a light coating of coconut oil to the breast shield funnel to minimize nipple discomfort and friction.

If you’re experiencing discomfort or pain while pumping, consider the following:

  • Are you using a new or gently used breast pump? If used, is the motor worn down?
  • Are your Silicone Collection Cup parts worn or damaged?
  • Have you tried lowering the suction pressure on your breast pump?
  • Is your nipple centered in the funnel?
  • Is your nipple rubbing against the sides of the funnel?
  • Have you measured your nipples and found an optimal breast shield size for BOTH breasts?


Difficulty achieving maximum output YES NO
Frequent clogged ducts or mastitis YES NO
Nipple rubbing the sides of the breast shield while pumping YES NO
Excessive areola pulling into the breast shield while pumping YES NO
Redness/irritation during or after pumping YES NO
Nipple noticeably white during or after pumping YES NO
Pain or discomfort at any point during or shortly after pumping YES NO
Sore/cracked nipples YES NO
Excessive pumping time with no or little milk output YES NO
Breasts still feel full after pumping YES NO

If you answered YES to any of the following, please consult with a lactation professional. There is no substitute for properly sized breast shields.

Do not continue to use your Silicone Collection Cups if you experience pain or discomfort while pumping. A different size funnel may be needed to optimize comfort and milk output.


Use the coin method for an approximate measurement of your pre-pump nipple size.

Measure your nipple pre-pump, hand stimulated at the base where nipple meets areola. Place the nipple into the smallest hole you can comfortably fit into without forcing, this is your nipple size. Measure each side as they can differ. Properly fitted flanges will be 1-3 mm larger than nipple diameter. Please consult with a lactation professional if you’re experiencing nipple pain or damage.

According to the Academy of Breastfeeding Medicine, freshly expressed breastmilk may be stored safely at room temperature (10–29°C, 50–85°F) for some period of time. Studies suggest different optimal times for room temperature storage because conditions vary greatly in the cleanliness of milk expression techniques and the room temperature.

Warmer ambient temperatures are associated with faster growing bacterial counts in stored milk. For room temperatures ranging from 27°C to 32°C (29°C = 85°F), 4 hours may be a reasonable limit. For very clean expressed milk with very low bacterial counts, 6–8 hours at lower room temperatures may be reasonable, but it is best to chill or refrigerate as soon as possible if the milk will not be used during that time.


Duckbill Valves
should be replaced every 1-2 months.

Silicone membranes that are sold as part of our Spare Backflow Protectors should be replaced every 4 months or sooner.

*For best results and longevity of the silicone breast shields, duckbill valves, and valve bases with backflow protectors, we recommend that they be boiled only once before initial use to sterilize them and not thereafter. After each subsequent use, we recommend that you disassemble the collection cups, silicone breast shields, duckbill valves, and valve bases with backflow protectors, rinse them with cold water, and then hand wash them in warm, soapy water. They should then be rinsed well and allowed to air-dry on a dedicated rack or clean cloth. UV sterilization or cold water sterilization is also acceptable.
