Safe materials and care

They can be sanitized through water steam or boiling, and cleaned easily with warm soapy water between pumps. Routine replacement every 1 to 2 months is recommended to maintain optimal performance and hygiene.

Practical notes and usage tips

Correct sizing can support a comfortable pumping experience; it’s normal for nipples to feel slightly different as pumping begins or ends. If you find a different size more comfortable on certain days, having multiple inserts on hand can help you explore what feels best for you without committing to a single option.

• Not a medical device; use as part of your personal pumping setup to explore comfort options.
• 4-piece set provides quick substitution during sessions or across days.

Real-world scenarios

In busy mornings or during late-night sessions, swapping to a 21mm insert can offer a distinct feel that supports a sealed fit and a calmer pumping rhythm. The goal is a comfortable, consistent experience that fits your individual needs.
