Q&A

Can these be used for baby food ?
Best Answer: I wouldn’t recommend using the Momcozy Temp-Sensing Milk Storage Bags for baby food. Momcozy specifically designs and labels these bags for breast milk storage and doesn’t confirm them for storing purées or other baby foods, so it’s best to use a container or pouch made for baby food.
What are the mom cozy storage bags made out of?
Best Answer: The Momcozy Temp-Sensing Milk Storage Bags are made of PE (polyethylene) + PET (polyethylene terephthalate). Momcozy also confirms they are BPA- and BPS-free.
Can these bags be used with Breastmilk Storage Container with Quick-Freeze Tray from Lansinoh to freeze the milk?
Best Answer: Yes, the Lansinoh Breastmilk Bags Storage Container is designed to fit most bags.
Are these bags compatible with the Zomee z1 pump?
Best Answer: Yes they are, just pour in the milk after pumping.
What are the dimensions of the bags?
Best Answer: A bag measures 0.04" x 3.94" x 8.58". Each has a capacity of 180 ml.
How do you heat these bags up?
Best Answer: You'd want to thaw out the milk first. Then you can heat it up to around 104°F by placing it in warm water or a milk warmer.
Are these bags freezer-friendly?
Best Answer: These bags are indeed freezer-friendly.
Are these bags reusable?
Best Answer: These bags are not reusable.
How many breastmilk storage bag do I need?
Best Answer: The number of bags you'll need can vary, but on average, most people use about 3 to 4 bags a day, storing 3 to 4 ounces at a time.

Great quality milk bags
I won this box of Breastmilk bags through an event, but I've been purchasing them for almost a year. I love that these bags are thin. Easy to unfreeze milk in and easy to poor milk out of. They fit in just about any milk warmer. They're leakproof, durable and a nice thing is they change colors based on the temperature for the milk. My all time favorite bags😊.

My Favorite Storage Bags!
These are by far my favorite storage bags! They are easy to open/close and the structure makes it easier to get the air out than other brands. The temp sensing feature is nice but in my opinion not necessary. These are a treat for me because my insurance pays for a different brand that I dont like nearly as much, so I dont spend money on others. I won these during a breastfeeding event on the momcozy app, so it was a very nice surprise!

Very convenient
This These Momcozy breastmilk storage bags are so convenient! I really like the easy-pour design, it makes transferring milk into a bottle much easier and helps reduce spills and wasted milk. The bags feel sturdy, seal securely, and are easy to store in the freezer. Very practical for expressing and storing breastmilk, especially if youre building up a freezer stash. Definitely a useful buy for breastfeeding mums!

Hard to pour, I get milk on the zipper part every time
Horrible to pour milk into. I hate the huge tabs up top, every time I go to pour milk into the bag, it gets onto the zipper part which then ruins the bag. Very annoying. I like how flat they lay, but the tab up top is a terrible design.

A Reliable Choice for Storing and Freezing Breastmilk
These Momcozy storage bags have been great for building up a milk stash. The temp-sensing color strip is a genuinely useful feature, letting you tell at a glance if milk is still cold enough to be safe without needing a thermometer.Pros:-Color-changing temp indicator takes the guesswork out of checking milk temperature-Double sealed seams feel sturdy, no leaks even when bags are laid flat in the freezer-Side spout makes pouring way less messy than bags without one-Great price for the quality compared to other storage bag brands

Clever design with mess-free pouring
These storage bags are excellent quality and the pour spout is such a simple but genuinely useful feature. Its much easier to transfer milk into a bottle without spills compared to standard storage bags.The bags feel thick and durable, seal securely, and stand well for filling. The measurement markings are easy to read and theyve stored well in both the fridge and freezer. The temperature aspect with color changing effects is brilliant and I adore using it to determine whether the milk is too hot or not.One of the better-designed milk storage bags Ive used.

Leak-Proof Breast Milk Storage Bags with Thoughtful Features
These Momcozy breast milk storage bags are a fantastic choice for breastfeeding mums. The leak-proof double seal gives confidence when storing milk in the fridge or freezer, and the self-standing design makes filling them much easier. The temperature-sensing colour change is a clever feature that helps indicate when milk is at a more suitable temperature, while the pour spout allows for mess-free transfers. Each bag is pre-sterilised, durable, and holds up well without tearing or leaking.
