My pump, the bottles I use, and nipples are all Medela, so when I had my first child, I only used Medela bags for the first few months. When I went to the store to purchase more one day, they were out of Medela bags so I had to go with Lansinoh bags. I’m glad I did! These bags are great for freezer storage as they store flat (Medela bags do not store as flat so it’s difficult to store them in the freezer without taking up a lot of space). The material is thick so you feel confident when you put your “liquid gold” in the bags. Now that I’m onto my second child, I will not use a different bag than the Lansinoh bags. I want to feel confident that I will not lose any milk when thawing the bags, and Lansinoh has given me that confidence!

These are fantastic! The lids ok these are better than the other lids I have for different Medela milk storage containers. The size is great for in the beginning when you pump small amounts, or for storing small amounts of milk for small bottles, or for whichever side produces less when you pump, or for mixing formula! We used these with my first born who was bottle fed breastmilk and formula- I used them to pump on my lower producing side, or to bring small amounts of milk with us (maybe for backup after the regular size bottle we brought), and we used them for mixing and storing formula. I am still using these bottles for my second baby-the measurements are cut into the plastic rather than being printed on, so the measurements havent washed off with use. Great, ... MoreThese are fantastic! The lids ok these are better than the other lids I have for different Medela milk storage containers.

I am a big fan of these bags and I'll summarize why:1) no tearing! I've used another popular brand of storage bags for several months until I started getting bags that had ripped while in the freezer. I don't beat up my bags or anything, but just through normal shuffling of things in the freezer the bags I had split at the bottom and I had leaks in my fridge when thawing out milk. This was tragic as it resulted in me losing several ounces of hard-earned milk!! The Medela bags are designed differently and the problems I was having with the old bags is impossible with the Medela bags due to the design (the bottom of the bag). So I'm happy. No tears or splitting bags here yet.2) I think the plastic is more durable. It's kind of a harder or more dense feeling plastic ... MoreI am a big fan of these bags and I'll summarize why:1) no tearing!

No tears or splitting bags here yet.2) I think the plastic is more durable. It's kind of a harder or more dense feeling plastic that's not prone to gouging or getting rips in them like the softer bags I had been using. The bag is still flexible enough to allow for easy storage and filling.3) very secure zipper. Not that I had problems with the other bags, its just that the Medela bags have a very leak tight zipper too.4) Easy to work with- despite some reviews, these are no more difficult to work with than other brands of bags I've used. The plastic is a little different, seems more dense, and feels different in your had compared to some of the other brands but I think this makes them more durable and less susceptible to ripping or getting holes in them while in a freezer. I have a french door fridge so my freezer is a big drawer at the bottom and things get piled on top of each other. I don't want a pizza box corner digging into my milk bag but if the plastic is durable enough, that is not a problem.

Medela is my favorite and only used brand. Have had no leaks, as compared to other brands, the quality has lasted years with multiple washings. I'd recommend to anyone. It's affordable and I did a ton of research this is the best on market! Highly satisfied.

When my best friend had her baby, he’s about 10 months older than my oldest, she got a similar flip top container for breast milk from the hospital. She ended up giving a couple to me when I had my oldest because she used it to store formula in her diaper bag when they were out and about. It was such a game changer because I didn’t want to have to carry around a formula container every where we went. Fast forward to having my youngest, I could not find the containers anywhere. I was really good about keeping everything so I didn’t have to buy all new stuff but I didn’t know what I was gonna do because the flip top containers were nowhere to be found. THEN I FOUND THESE. I LOVE that these are twist top and well secured. As a formula feeding mom, the only formula ... MoreWhen my best friend had her baby, he’s about 10 months older than my oldest, she got a similar flip top container for breast milk from the hospital.

I was really good about keeping everything so I didn’t have to buy all new stuff but I didn’t know what I was gonna do because the flip top containers were nowhere to be found. THEN I FOUND THESE. I LOVE that these are twist top and well secured. As a formula feeding mom, the only formula containers I found were kind of bulky. I know these were meant for breast milk but we would put 2-3 scoops of formula in these and we know it was 1 tube to how ever much water we needed. So if we put 2 scoops in, we needed to fill the bottle up to 4 oz of water. It made everything so easy on the go because it was already portioned and we would just take how ever many tubes we thought we would need plus 1 extra. Plus, we didn’t have to pre make bottles. We would just put the water we needed in the bottle and when our girls started to fuss, we just poured the tube in the bottle. No mess, no measuring in the moment, just dump it in and go. I bought the big box of 12 and split it with my cousin who’s baby is 6 weeks younger than my youngest. I will always recommend this product. Whomever came up with this product, market it to formula moms too. Not all moms can breast feed and not all couples with kids are couples with a breast feeding caretaker but we still need easy carry items like these. 100000/10 recommend

To be honest, I didn't even know I could freeze my milk in these containers until now. I was given a bunch of these. I screw them to my breast pump and pump directly into them. I then pour these into a larger bottle that is in the fridge. I do this until I get a 6 oz bottle then I bag it up and freeze it. Also you can repurpose these as dry formula containers. You can fit 8 oz worth of Powdered formula in these and just drop them in the diaper bag.

I love how versatile these bottles are. They can go from the pump to the fridge to the freezer. Easily able to swap the lid to a nipple bottle and back. The pump works amazing and every part of their products work so well together. They’re also great for single use formula powder if you’re travelling.

Fantastic breastmilk storage containers!

Great containers for storing milk. I find that they are perfect sizes too so you can;- use what u need & keep topping up without wasting any unused milk.- easily store them with limited space in the freezer.- warm up or thaw them out quicker than in a bottle because of their narrow size.Also cool that they have the label section to mark the bottles, are reusable which save me heeps & are good quality containers that are dishwasher safe!Only downfall really is that I can’t seem to find a a marker that will stay on it even after freezing, so it would be great if it came with one or some labels just to complete the pack.

Great volume and quantity

These were super convenient for when I first began pumping. They fit right on to my Medela pump, and also work directly with the Medela “Calma” nipple I ordered. These helped with confidence, as I was not pumping high volumes. They measure every ML from 10-80. Having a set of 12 meant I could have storage for pumping during the day and pump several times before needing to clean and sterilize larger volume bottles which came with my insurance-provided pump. I have frozen 2 bottles and haven’t yet thawed them to speak to how they hold up with freezing/defrosting, but the quality seems solid. I use these mostly for supplementing my own milk between or after feedings if my now two-month old baby still seems hungry (wants a snack). I still use them for day pumping ... MoreThese were super convenient for when I first began pumping.

I still use them for day pumping (versus early morning when I have a lot of milk) or pumping after a feed. I use a wet-erase marker on the lid to keep track of the date (and sometimes the time) of the pump and store them in the fridge. These totally helped with my pumping and feedings. Would recommend!

Must have !

i bought these because i needed bigger bottles to store pumped milk in. i love the sturdy base on these and have had no problems with leaking either. theyre a great value for the low price and very easy to clean. we've been using these for about a week and i will definitely be buying more next time im in the store
