Not getting as much milk or not emptying well in our silicone flanges is usually one of two things:
Not getting deeply enough in the tunnel: Try the suggestions here. Let us know if you need real-time guidance.
Wrong flange size: To minimize swelling that puts pressure on milk ducts, we recommend using the smallest size that you can fit into comfortably. There shouldn't be more than 1/8" (3mm) between your centered nipple and the side of the tunnel. This usually means sizing down at least one flange size.
