What Makes Momcozy Your Top Choice?
Warm Tips
Squeeze Out The Air
Prevent milk spoilage. And bursting of the bag due to excessive pressure during freezing.
Large Write-on Label
Each bag features a spacious writable tab on the top for tracking purposes.
Tear Off One Bottom Corner
Hold the milk bag and tear one corner gently as per the instructions, avoid tearing the double corners, or both corners will squirt breastmilk.
Thaw with Baby Bottle Warmer
After thawing, the milk can be heated to around 40°C (104°F) by placing it in warm water or a milk warmer.
What Factors Affect The Accuracy of Momcozy Breast Milk Storage Bag Capacity?
1. After pouring milk into bag, we need to fully unfold the four corners of the bag to get an accurate capacity. Or the measured value will be higher than the actual capacity.
2. The bottom of the bag is irregular, which will cause a 0.4-0.8oz/10-18ml deviation due to the degree of unfold of four corners & user's usage habits.
3.Max capacity is 6OZ, leaving enough space for exhaust & freeze. Beyond 6OZ, freezing will easily cause the bag to burst.

I LOVE that they have the temp sensing little button. But you do have to shake the bag around for an accurate reading. I also really love that you can rip it at the bottom corner to dump it, this makes pouring a DREAM. No more spilled milk!

I’ve been using these for about a week & a half. I started with the Lansinoh bags but they fell apart in my momcozy bottle warmer when I thawed them from frozen. Milk was everywhere. With these, I can thaw them in the warmer & they keep their structure. They’re pretty sturdy bags, actually. Everything I have is momcozy— the bags, the pump & the warmer so I imagine they were intended to be used together. They do not buckle when I pour my milk in from the pump (& I usually pour them FULL like 6-7 oz). The bottom opens up & flares out when they’re full making them self standing so that’s nice. My husband lays them horizontally in our freezer & the bottom collapses again to freeze them flat so we don’t have any issues with space. I have held them upside down, played w the milk inside like a squishy, & simply dropped them & haven’t had any issues with leaking. They’re built tough. I will consistently buy them for storing milk. It’s a really nice, thick plastic bag. I wouldn’t reuse them or anything, definitely once & toss, but they’re worth the money spent for sure.

I've been breastfeeding and freezing extra pumped milk for over 2 and a half years now between two babies, and I've tried no less than 7 other brands of milk storage bags in that time. I had never found one that I honestly liked - until I started using these. They freeze flat, are durable, and I haven't had any leaking issues with thawing thus far. They feel sturdy without being bulky - they feel like a high quality product. I never use the measuring lines on the bags and have always pre measured milk in bottles before storing, so I can't speak to the accuracy of the measuring lines. These bags have combined all of the positive attributes of other brands, without incorporating any of the negatives, in my opinion. I'll never use another brand now that I've found these.

I have tried a couple of different storage bags and these by far are the best ones! They will lay flat in your freezer, they are thick so they won’t tear / leak and I love how it tells you the temperature at The bottom. They work GREAT with the momcoozy bottle / bag warmer!!

I have tried all different types of bags. These are by far my favorite! They are stiff when pouring milk which helps prevent leaks, thick to avoid accidental punctures, they seal well and freeze flat if desired. The temperature indicator is not the best for me personally but I always check temp on warmed milk anyhow so not a deal breaker. I recommend these for any pumping mommas out there.

I like these bags, good quality and the plastic seems a little thicker than most. I trust the zippers on the top and haven’t had any leakage so far. Love that it has the temperature sensor on the bags. Easy to open good design and good value for the money. Nice clear color.

After trying 3 other brands of breastmilk storage bags I have to say these are the best! The thickness, durability, and ease are unmatched. You get great value for your money.The last bags I used before these were Lansinoh milk bags and I absolutely hated them. They broke every time they were defrosted and don’t stand up when pouring milk in like these do. I had no issue when defrosting and I put 5oz in these but 4oz in other bags just didn’t hold up or trapped more air in the bags no matter how much or little milk I put.I’m a forever customer as long as momcozy keeps up the quality of these bags!

I stopped pumping and now I’m making my own purée foods so these bag are good to store extra purée foods in the freezer and pull when needed. They have not leaked, definitely a good option for a gift value cause you can never have too many of these.

Good storage but the colour changing for temp is rubbish. I pour fresh milk into it which is how baby would drink it straight from me and it says its too cold for baby? Yet when I warm it to the same temp from the fridge, it says its too hot..
