Frequently Asked Questions
What is 2-Phase Expression?
Medela's 2-Phase Expression mimics the natural sucking pattern of a nursing baby. Phase 1 (Stimulation) uses short, rapid cycles to trigger letdown. Phase 2 (Expression) uses slower, deeper cycles to efficiently extract milk. Most pumps use the same speed for the entire session.
What are PersonalFit Flex connectors?
PersonalFit Flex connectors are the funnel-shaped parts that attach to your breast. They flex to accommodate different body types and movements, which many users find more comfortable than rigid flanges. 5 sizes are included.
Why is the tote bag significant?
The Pump In Style comes with a tote bag with an insulated cooler compartment, ice pack, and organizing pockets for all pump accessories. You can carry the entire pump setup to work in one professional-looking bag. Most pump competitors require you to purchase a bag separately.
