“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.”

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.

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).

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.

I was a bit undure about mumma bump but i found their products AMAZING!!! they were packaged so well and the breat pump is amazing design
These are amazing and love them and so does my partner when he warming it up rather then using the plastic throw away ones I have heaps still because I now never use them.
Definitely going to purchase more when I go back to work but the 6 pack is the best ❤️🥰
Happy with the quality of the products. The advertisement is truthful and the items are as eexpected.The only issue I had is the delivery time, in both instances it exceeded 5 days.
These are so convenient for storing milk
In the fridge, the freezer and in the nappy bag! Added bonus of being able to heat up the milk to the perfect temperature without spilling, or damage to the bag
My initial order was a double pump and x4 milk bags. When I got my order I had only received half of my order and the package a little damaged and the boxes don’t come sealed. After I contact the customer service, I have received the rest of my order and an apology for any inconvenience.
I haven’t used the product yet. But so far with the fact they sent ALL my order eventually. I am pleased. Happy to write a review once I make use of the product. Thanks
Those MammaBump Eco-friendly breast milk bags are such a great idea. I found myself going through so many disposable milk bags in a day that these have been a great addition to my pumping journey. Love that they roll up and are easy to take out for on the go pumping. The lid is secure and makes me feel comfortable knowing my liquid gold is safe till it makes its way home to the fridge/freezer.
I absolutely LOVE my MammaBump breast milk bags! I can fill them up and travel with them easily! And it doesn’t take up much room at all! I can also fold them when they’re not in use to have more space! This was a must buy for me!
I love that they are re-usable and that the milk is so easy to pour into them. Its also so easy to write on them and remove old writing. In my previous pregnancy the amount of plastic bags I used was ridiculous.
I love these bags!! They have been so helpful and are such high quality. I love that they can go in either the fridge or freezer. They have saved me so much money as I just reuse after every use!! Super happy with the look and practicality of these bags. Such a must have!
I went back to work this week and use these to store the milk I pump at work. They fold up so they don’t take up any space at all in my bag and are so easy to clean. They seal well and I haven’t had any issues with leaking. I would definitely recommend these and would buy again!
Love these milk saver bags, they hold a lot of milk and are very durable. The fact that you don’t have to throw them away after one use is fantastic. Could not be happier with them.
Looking for something less bulky for milk storage? These are great! I can take 3 or 4 in my diaper bag for the whole day. No leaking and easy to sterilize after each use!
Previously I used disposable milk storage bags & was looking for a more durable option. After I purchased my Luna Breast pump, I saw these eco-friendly breast milk bags and didn't think twice. They have been very easy to use & clean. They also stand up in the freezer perfectly.
