How long can I store expressed breast milk?

Common CDC guidance is up to 4 hours at room temperature, 4 days in the refrigerator, and about 6 months (up to 12) in a deep freezer. Always label each container with the date it was expressed.

Can I reuse milk storage bags?

No. Pre-sterilized milk storage bags are single-use to protect your milk from contamination. Bottles and cooler bags are reusable when cleaned per the manufacturer's instructions.

Do you ship nationwide?

Yes. Maternal Relief Co is headquartered in the Dallas-Fort Worth area and proudly serves eligible patients nationwide, shipping discreetly to all 50 states.
