“I love that they are re-usable and that the milk is so easy to pour into them. It's also so easy to write on them and remove old writing. In my previous pregnancy the amount of plastic bags I used was ridiculous.”

Good To know
Better for your breast milk and for your baby
Crafted from 100% FDA-approved food-grade silicone, our MammaBump breast milk bags are completely plastic-free, ensuring there’s no risk of chemical leaching. These reusable storage bags are also free from BPA, BPS and phthalates, providing a safer option for your little one.

MammaBump reusable breast milk storage bags are designed for your convenience—they’re easy to sterilize, dishwasher-safe, and freezer-friendly! Our eco-friendly bags also come with a handy silicone carry strap, making it simple and safe to take your liquid gold with you wherever you go.
How do I make sure my MammaBump eco-friendly breast milk bag stay in good condition?
To keep your bag in top condition, avoid using bleach-based cleaners or sterilizing tablets, and please don’t use UV sterilizers, as they may shorten the product’s lifespan. Our MammaBump eco-friendly breast milk bags are dishwasher safe, microwave safe and boil safe. Please make sure to store them away from sharp objects.
How to store breast milk safely?
Freshly expressed breast milk can be safely kept at room temperature for up to four hours. If you need to keep it longer, it’s best to store it in the refrigerator, where it can stay fresh for up to four days, or in the freezer, where it can last for up to 12 months (though six months is ideal). When it comes to saving both cost and space, our eco-friendly reusable breast milk storage bags are a mom's best friend.
Made from sturdy, food-grade silicone, these bags are thoughtfully designed to keep your precious milk safe, organized, and sanitary. Whether stored in the fridge or freezer, our silicone bags can be laid flat or stood upright, making them as versatile as they are practical.
