Quick answer

Setting up and cleaning your Lansinoh Thrive 2-in-1 wearable cups is straightforward: assemble the parts correctly before each use, and wash them thoroughly after every pumping session to maintain hygiene and pump performance.

Why proper setup and cleaning matter

The wearable cups are designed to fit seamlessly with your Thrive pump, but a small misalignment during assembly can reduce suction or cause leaks. Regular cleaning prevents milk residue buildup that can clog valves and reduce pump efficiency over time.

Step-by-step setup and cleaning guide

  1. 1. Assemble the cups: Attach the silicone diaphragm and valve to the cup body, then connect the cup to the pump tubing or directly to the Thrive pump unit. Ensure all parts click or fit snugly without gaps. Common mistake: Forgetting to seat the diaphragm flat can cause weak suction.
  2. 2. Position the cups: Place the assembled cup inside your pumping bra or nursing tank, centering the nipple in the tunnel. Adjust the bra for a secure hold that keeps the cup upright during pumping. Check that the cup is level — a tilted cup may leak or collect milk unevenly.
  3. 3. Pump and monitor: Start your Thrive pump at a comfortable suction level. Watch for consistent milk flow and listen for air leaks. If suction drops, pause and recheck the cup assembly. A hissing sound often means the valve is loose or the diaphragm is misaligned.
  4. 4. Disassemble after use: Remove the cup from your bra and detach it from the pump. Separate the diaphragm, valve, and cup body. Rinse each part under cool water immediately to prevent milk from drying on surfaces. Don’t let milk sit in the cup — dried residue is harder to clean and can harbor bacteria.
  5. 5. Wash thoroughly: Wash all parts (except tubing) in warm, soapy water using a dedicated bottle brush. Pay special attention to the valve opening and diaphragm edges where milk can hide. Rinse well and air-dry on a clean towel or drying rack. Avoid using abrasive sponges that can scratch the plastic and create hiding spots for bacteria.
  6. 6. Sanitize regularly: Once daily, sanitize the wearable cups by boiling for 5 minutes, using a steam sterilizer, or running them through the dishwasher on a hot cycle with a sanitize setting. Check the manufacturer’s instructions for heat limits. Over-sanitizing can wear out silicone parts faster — once a day is sufficient for most routines.
