Learn how to use Elvie Catch for leak-free milk collection, from inserting and positioning to cleaning and troubleshooting. Get practical tips for comfortable, hands-free collection.

Elvie Catch is a wearable milk collector designed to capture letdown from the opposite breast while you nurse or pump. Unlike a breast pump, it uses gentle suction to collect milk passively, so you can build your stash without extra pumping sessions. This guide walks you through everything from first-time setup to daily use, cleaning, and troubleshooting.

Whether you're a new mom or adding Elvie Catch to your routine, understanding the proper fit and placement is key to a leak-free experience. We'll cover the step-by-step process, share practical tips, and address common questions so you can use Elvie Catch with confidence.

Getting to Know Elvie Catch

Elvie Catch is a soft, silicone cup that fits inside your bra to collect milk passively. It's designed to be worn on the breast you're not nursing or pumping from, catching letdown that would otherwise soak a nursing pad. The cup holds up to 1 oz (30 ml) per side, making it ideal for building a small stash over time.

The cup is made from food-grade silicone and is BPA-free. It comes in two sizes (S/M and L/XL) to accommodate different nipple and areola sizes. Getting the right fit is essential for both comfort and leak prevention, so measure yourself before purchasing or use the included sizing guide.

  • Check the sizing guide to choose between S/M and L/XL.
  • Elvie Catch is not a pump; it relies on passive suction, so it won't stimulate milk production.

Step-by-Step: How to Insert Elvie Catch

Start by washing your hands and ensuring the cup is clean and dry. Fold the cup in half, bringing the top and bottom edges together. While holding the fold, place the cup over your nipple and areola, then release. The cup should create a gentle seal, but not feel tight or uncomfortable.

Adjust the cup so that the spout is pointing downward or slightly to the side, depending on your bra style. The spout is designed to pour milk out easily, but it should not press into your breast tissue. Once positioned, put on your bra and adjust the straps to ensure the cup stays in place without shifting.

  • Practice folding and inserting a few times before your first use to get the hang of it.
  • If the cup feels painful or leaves deep marks, you may have the wrong size.

Wearing Elvie Catch While Nursing or Pumping

Elvie Catch is designed to be worn on the opposite breast while you nurse or pump. For example, if you're nursing on the left side, insert the cup on the right. The suction from nursing or pumping can trigger a letdown on both sides, and Elvie Catch will collect that milk.

You can wear Elvie Catch for up to 90 minutes at a time. It's safe to wear while you're active, but avoid bending over or lying down, as milk may spill. If you're using Elvie Catch with an electric pump like Elvie Pump, you can wear it on the opposite side to maximize collection.

  • Keep a burp cloth handy in case of spills during insertion or removal.
  • Empty the cup when it's about ¾ full to prevent overflow.

Removing and Storing Collected Milk

To remove Elvie Catch, gently break the seal by lifting the edge of the cup. Pour the collected milk into a storage container or breast milk bag. You can combine milk from multiple sessions as long as you cool it first and follow safe storage guidelines.

If you're using breast milk bags, consider using Breast Milk Bag Flatteners to save space in the freezer. These flatteners make bags stack neatly and thaw faster. For on-the-go storage, the Seoul Max Pump Backpack offers insulated compartments to keep milk cool while you're out.

  • Label stored milk with the date and time.
  • Use cooler packs when traveling with collected milk.

Cleaning and Maintenance

After each use, rinse Elvie Catch with cold water to remove milk residue, then wash with warm soapy water. You can also sterilize it using steam or boiling water for 2-3 minutes. Avoid using harsh detergents or abrasive sponges that could scratch the silicone.

Elvie Catch is dishwasher-safe on the top rack, but hand washing is recommended to prolong its life. Allow the cup to air dry completely before storing. Regularly inspect the cup for tears or deformation, and replace it if you notice any damage to maintain a leak-free seal.

  • Use a dedicated brush to clean the spout area thoroughly.
  • Do not use oil-based nipple creams with Elvie Catch, as they can break down the silicone.

Troubleshooting Common Issues

If you experience leaks, check the fit and position. The cup should sit snugly against your breast without gaps. If the seal is broken, reinsert the cup. Also, ensure your bra is supportive enough to hold the cup in place without compressing it.

If you feel discomfort, you might need a different size. Elvie Catch should be invisible under clothing and comfortable enough to wear for extended periods. If you notice reduced suction over time, clean the cup thoroughly and check for damage.

  • Try different bra styles to find one that keeps the cup secure without pressure.
  • If leaks persist, contact Elvie support for personalized help.

Elvie Catch is a simple, effective way to collect milk passively and build your stash without extra pumping time. By following this guide, you can ensure a comfortable, leak-free experience every time. Remember to prioritize proper fit, regular cleaning, and safe storage.
