Filling and Sealing Elvie Breast Milk Bags

Start by washing your hands and ensuring a clean surface. Open the bag by tearing along the perforation, and use a marker to note the date and amount of milk. When pouring milk, leave about an inch of space at the top because milk expands when frozen. Overfilling can cause the bag to burst or leak.

Seal the bag by pressing the zipper closed from one end to the other, ensuring it's fully sealed. For extra security, you can double-check the seal by running your finger along the zipper. Always use a new bag for each pumping session to maintain hygiene and prevent cross-contamination.

• Leave space for expansion to prevent leaks.
• Label each bag with the date and amount to track freshness.

Storing Milk in the Freezer

For optimal storage, lay the filled bags flat in the freezer. This allows the milk to freeze in a thin, uniform layer, which not only saves space but also thaws faster later. Once frozen, you can stack the bags vertically like files in a folder.

To keep your freezer organized, consider using the Breast Milk Bag Flatteners. These handy tools help you flatten the bags evenly, making them stack neatly and efficiently. This is especially useful if you're storing large quantities of milk and want to maximize freezer space.

• Freeze bags flat for quicker thawing and space efficiency.
• Use flatteners to keep bags uniform and easy to stack.

Thawing Breast Milk Safely

When you're ready to use the milk, thaw it in the refrigerator overnight or place the sealed bag in a bowl of warm water. Avoid using hot water or a microwave, as these can create hot spots and destroy valuable nutrients. Never refreeze thawed milk.

Once thawed, gently swirl the bag to mix the separated cream. Do not shake vigorously, as this can break down proteins. Use the milk within 24 hours of thawing and discard any leftovers after a feeding.

• Thaw in the fridge or warm water, never microwave.
• Swirl gently to mix, and use within 24 hours.

Feeding Your Baby with Elvie Bags

After thawing, you can pour the milk into a bottle or feed directly from the bag if it has a spout or can be snipped. If using a bottle, pour the milk and warm it to your baby's preferred temperature. Always test the temperature on your wrist before feeding.

If you're on the go, the Breast Milk Cooler can keep your milk chilled for up to 24 hours, making it easy to transport milk from the bag to a bottle when needed. This is perfect for outings or trips where you don't have immediate access to a fridge.

• Pour milk into a bottle or use the bag directly if possible.
• Use a cooler to keep milk cold while traveling.
