Quick Answer
To get a secure fit with your Willow 360, confirm your flange size, insert the correct insert, position the pump over your nipple, and press firmly until it seals. Then adjust the bra tightness and check for gaps before starting.
Why Fit Matters More Than You Think
A proper fit is the difference between a comfortable, efficient pumping session and one that leaves you frustrated. If the pump isn't sealed correctly, you may experience leaks, reduced suction, or discomfort. The Willow 360 is designed to be leak-proof, but only when it's worn correctly.
The right fit also affects how much milk you collect. A secure seal ensures the hospital-grade suction works effectively, stimulating milk flow and emptying your breasts more completely. Taking a few extra minutes to check your fit can save you from wasted milk and wasted time.
What If the Fit Doesn't Feel Right?
If you feel pinching, slipping, or notice milk leaking, the most common culprits are an incorrect flange size or a bra that's too loose. The Willow 360 comes with both 21mm and 24mm flanges, so you can switch to find the best match. Also, make sure your nursing bra or snug top holds the pump firmly against your chest without being painfully tight.
Step-by-Step: How to Wear Your Willow 360
- Measure Your Nipple: Measure your nipple diameter (not the areola) while it's at rest. Use the sizing guide to determine if you need the 21mm insert or the 24mm flange. A too-small flange can pinch; a too-large one can pull in areola tissue. Re-measure after a few weeks—your size can change.
- Insert the Correct Size: If you need the smaller size, snap the 21mm insert into the flange. Make sure it's seated firmly and evenly. If you're using the 24mm flange, skip this step. Check that the insert is fully seated to avoid gaps.
- Position the Pump: Center your nipple in the flange opening, then press the pump firmly against your breast. Ensure the flange is flush with your skin and there are no gaps around the edges. If the pump feels loose, reposition and press again.
- Secure with a Snug Bra: Wear a nursing bra or a snug, non-underwire top that holds the pump in place. The bra should be tight enough to keep the pump from moving but not so tight that it compresses your breast tissue. A too-loose bra is the #1 cause of leaks.
- Check for Gaps Before Starting: Look in a mirror or feel around the edges of the pump. If you see any gaps or feel air escaping, adjust the pump or tighten your bra. Then start the pump and listen for a consistent suction sound. If you hear air hissing, stop and re-seat the pump.
