FAQs
How to make sure of efficient pumping?
1. Ensure the breast pump and accessories are correctly installed, and the flange fits snugly to the breast.
2. Choose the correct flange size using the included nipple measure tool. Available flange sizes (15/17/19/21/27mm) can also be found on the Momcozy website.
3. Replace silicone accessories every 3 months based on their condition.
4. Recommended bra styles: full coverage, stretch fabric, nursing buckle, or wireless bras for optimal pumping comfort.
How can I confirm the correct flange size?
Before purchase, consult Momcozy’s flange size guide. After purchase, use the nipple measure tool (included) to find the appropriate flange size. Remember, your breast size may change before and after pumping, so measure accordingly.
When should I replace breast pump accessories?
All parts that come into contact with breast milk are BPA-free. Replace parts regularly for optimal performance. Inspect valves and diaphragms for wear and replace every 2-3 months.
- Diaphragms, duck valves, and inserts: Replace every 2-3 months
- Flange shields and milk collectors: Replace every 6 months
Do wearable pumps decrease milk supply?
A wearable pump’s impact on milk supply depends on suction power. Proper suction is essential for efficient milk removal and maintaining supply. The high suction capability of the Momcozy S12 Pro ensures thorough milk extraction without compromising production.
