Practical guidance: To maximize comfort, experiment with the two sizes in the pack and monitor how the seal and suction feel during a session. Keep an eye on changes in nipple size across stages, and refer to the sizing guide when choosing which insert to use. While the inserts come with a reasonable lifespan and warranty, listening to your pumping cues and swapping in a different size when needed can help you maintain a steady, comfortable routine without overpromising results.
