Quick Answer
Use Elvie Curve on one breast to capture letdown while nursing or pumping on the other, and place Elvie Catch in your bra on the opposite side to collect passive leaks. This combo maximizes every drop with hands-free ease.
Why Combine Both?
Elvie Curve is a manual, in-bra silicone breast pump that uses one-press expression to capture bonus milk during feeding or pumping sessions. Elvie Catch is a pair of silicone milk collection cups designed to catch every last drop of milk with leak-free confidence. Using them together lets you collect milk from both breasts simultaneously, even if one side is passively leaking while the other is actively expressing.
This approach is especially useful during early breastfeeding when letdown can be strong and unpredictable. Instead of wasting milk on nursing pads, you can save it for later feeds or freezer stash.
Trade-Offs to Keep in Mind
Elvie Curve holds up to 4 oz, while Elvie Catch holds 1 oz per cup. If you have a heavy letdown, you may need to empty the Catch more frequently. Also, because both are worn in-bra, they add bulk under clothing, so consider your outfit and whether you need to be discreet.
Neither device is intended for full pumping sessions; they are best for capturing bonus milk, not replacing your primary pump.
Step-by-Step: Using Elvie Curve and Elvie Catch Together
- Prepare Both Devices: Wash your hands and ensure both Elvie Curve and Elvie Catch are clean and dry. Assemble each according to the instructions. Check that the silicone flanges are properly seated to prevent leaks.
- Position Elvie Catch on the Non-Nursing Side: Place Elvie Catch inside your bra on the breast you won't be nursing or pumping from. Center it over your nipple so it can collect passive letdown. Adjust your bra tightness to keep the cup snug but comfortable.
- Attach Elvie Curve to the Nursing Side: Position Elvie Curve over your nipple on the breast you plan to nurse or pump from. Press the button once to create a gentle suction and start expressing bonus milk. If you feel discomfort, release the pressure by pressing the button again and reposition.
- Nurse or Pump as Usual: Begin nursing your baby or using your primary pump. The Elvie Curve will collect milk on that side, while Elvie Catch captures leaks on the other. Keep an eye on the fill levels—empty Elvie Catch when it reaches 1 oz to avoid overflow.
- Empty and Store Collected Milk: Once you're done, carefully remove both devices and pour the collected milk into a storage container or bottle. Label with the date and time if storing. Follow proper milk storage guidelines—use within 4 hours at room temperature or refrigerate promptly.
