5 Stars By Hai M Nguyen on 2016-04-10 Love love the new edges! I have been exclusively breast pumping for almost two months now since my son is at the NICU so I need to freeze my milk. After doing some research I concluded that the Honeysuckle bags were the most bang for my buck while being of quality. However, they can get expensive for those who have to exclusively pump like myself. So last week after I noticed I was running out of the Honeysuckle bags I decided to give Lansinoh a try since they are amazons top rated breastmilk storage bag. After I received them I immediately wanted to return. I was not pleased with the bags when I compared them to the Honeysuckle bags. So 2 days ago I logged on to 2DayDeliver to do a return. Turns out that they gave me an option to exchange them for the new and improved bags! The edges are now wider and the bag seems thicker! I am so glad lansinoh listened to its customers who had complained about the milk leaking because the edges were too small. I feel that everyone who left a bad review should give these bags another chance now that they have improve them. They are honesty the best quality for the price. I will no longer be purchansing the more expensing Honeysuckle bags because the new lansinoh bags are just as well made if not better! Thank you thank you!
5 Stars By SoCal Mama of 3 on 2017-05-04 Fits 10 oz max In case you're curious about the max volume... 10-oz and the bag stays intact even after expansion upon freezing. (Yep there are bubbles in that pictured frozen 10-oz bag, my bad).
I once tried 11 ounces but could not close the bag.
I only freeze 10 oz portions from the morning pump when I have the most milk. In other words, I don't combine multiple pump sessions into one bag because the milk would be at different temperatures (imagine adding a cold egg into warm soup). One way around this is to bring morning milk and afternoon milk to the same temperature by chilling in the fridge, then, once both bottles are cold, transferring to a bag. I don't do that often because it's too painful to see chunks of creamy hindmilk left on the bottle once chilled. I used to store in 3-4 oz portion sizes (I'm still not sure how much baby needs to eat in one feeding since she's EBF) but why waste bags if I have enough more than one bottles' worth? Just defrost and pour into 2-3 bottles for daycare/babysitter.
How I freeze and store: I place the fresh bag flat in a clear shoe box to freeze into a smooth shape while minimizing freezer smells. Once frozen, I store upright in gallon-sized ziplock bags.
4 Stars By JSK on 2017-04-13 Old vs New version storage bags I was running out of milk storage bags and went ahead to order a new box. This was the first time I had seen the newly updated version. I had one of each, the older + latest version so I decided to take some side by side photos.
Clear Storage Bag: The new bags look like they have a reinforced seam. This is a plus - some of my old bags would leak. The perforations at the opening are different. I thought it was multiple pieces to rip off - but it actually tears off as one piece. It also sticks a little more than the older version so there's slightly more effort to get them open but not a big deal here. The bag can stand on its own if it has enough milk contained inside. White Dispenser bag: I like to use the dispenser bags because it keeps the actual storage bags clean and dust free. The new dispenser bags don't have the slit down the middle which I started to enjoy with the older bags - rather than opening/sealing the entire bag down the side. Wish they had kept that feature but again, not a deal breaker.
I used to switch between these and generic storage bags from a big bix store depending on price - but now pricing is very similar, so I choose to purchase these Lansinoh bags since the brand is focused on nursing moms. Also, feel like they use less plastic than the generic version. (based on density of the bag) I would recommend this brand of bags for nursing moms.
Some tips: To transfer milk from bottles to the bags, I use the breast shield as a funnel after I pump. I freeze them flat and then "file" them upright in the freezer. I keep my pump, paper towels, hair tie and fine tip marker in my tote at all times for my pump sessions. If you have a back-up set of pump parts, leave some at the office or wherever you work. If you do forget a pump part, you can hand-express the milk out. It's a workout and not as efficient, but it helps when you're in a pinch. You don't have to wash your parts/bottles every time you pump. You can store them in a clean plastic bag or container in the fridge until the next session. I give them a full wash after a few days.
3 Stars By J. Maclauchlan on 2013-07-21 Our least favorite breastmilk storage bags We have used four brands of breastmilk storage bags: Nuk, Honeysuckle, Medela, and Lansinoh. It's worth noting that we haven't had a leak with any of the bags, but we primarily use them for refrigeration. Based on other reviews, the "true" test of the bags seems to be freezing and subsequently thawing them. We have frozen and thawed a few of each brand with no leakage.
Nuk: These are our favorites. They are slightly smaller (maybe half a centimeter?) than Honeysuckle and Lansinoh bags, but you're not supposed to put more than 6 ounces in any of them anyway. They stand up the best, which is very convenient when pouring milk into them. I do hold the bags while I pour it in, but every now and then I lose my grip and these don't fall over like the Honeysuckle and Lansinoh bags. The plastic is thicker than the Lansinoh bags. These are also available at Wal-Mart, which is convenient if you can't wait for an amazon order to be delivered. The area where you write on is clear, and it's white with the other bags. I prefer the white background, but that's because I have black countertops. Small potatoes, though. The measurement is pretty close to the Medela bottles I pump in to. These are usually about 18-20 cents a bag depending on the quantity you purchase.
Honeysuckle: Our second favorite, these bags have more of a vinyl feel than a plastic feel. They're floppier than the Nuk bags, but more sturdy than the Lansinoh bags. The seal makes a clicking sound (like a Ziploc bag) when sealed, which is nice. The Nuk bags don't make that sound. My husband has had issues with the bags dripping milk out of the seal area when pouring instead of about a centimeter above the seal, where it is supposed to pour out of. The measurement seems to be off by half an ounce compared to the Medela bottles (if I pump 4.5 ounces, it will read as 4 ounces on these bags). These are about 18-20 cents a bag unless you buy a quantity of 300, in which they are 14 cents a bag (based on pricing as of July 2013). These are only available online, at least in my area (Virginia Beach).
Medela: These bags could be convenient for some because you pump directly into the bags. They work just fine, but I just prefer the bottles in case I adjust while pumping the milk can't splash out. They are a stiff plastic, which means they stand up well. They only hold about 5 ounces (compared to the 6 ounces for the other bags...but I've put 9 ounces in the other bags with no issue). They are a little harder to pour out of because of the design of the bag (the milk comes out about an inch above the seal). The measurement is accurate to the Medela bottles. They are also available in retail stores (Babies R Us, some Wal-Marts). These are more expensive at about 30 cents a bag.
Lansinoh: It's a shame that these bags are the most widely available, because they are the worst. They're thin, floppy, and have very little seam allowance. Based on other reviews, the bags changed in 2011. Prior to that, they were great, which is why the reviews on amazon are so high. They are about 18-20 cents a bag. They work fine in a pinch, but there are better options out there for the same (or better!) price.
Hope this helps! :)
1 Stars By Felicia on 2017-07-05 Leaky bags...all of them. Beyond frustrated that the entire box of bags leaks. Breast milk spilled out all over my freezer. The package says new reinforced bags but they need to try much harder. The last package only had a few that leaked but this is ridiculous. I have to throw the whole box away.
5 Stars By Sam &amp; Tierney on 2017-09-27 Lansinoh vs Nuk storage bags I have previously used the NUK storage bags and omg these are sooooo much better!! The Nuk bags broke on me at least 3 times and often leaked. Milk would ALWAYS get stuck in the threads so I'm not surprised.
These bags have amazing sealing threads - you can HEAR them click and feel how well they seal. Also, the side seams are reinforced. There is like 1/4 centimeter all around the bag to prevent leaks.
The plastic is a little thinner than the Nuk bags, but overall it actually feels nicer and higher quality.
We have sticker labels for daycare, and I stick them on my storage bag before peeling them off and putting them on the bottle in the morning. The labels removed from the Nuk much easier, but it's not terrible removing them from the Lansinoh ones. I think it's because the plastic is thinner/more pliable.
4 Stars By Shawn & Kristen Newton on 2017-10-22 Good Bags, just be careful of flaps while pouring milk into them. I previously had Babies R Us brand but ran out, so we decided to get these because I had some issues with milk leaking out of the other bags after being frozen and thawed. I have not frozen and thawed one of these bags yet to test that issue, but otherwise they seem like good bags. I like the double ziplocks. The writing part of it is easier that the other bags I had. I can just use a regular pen instead of a sharpie. I also like how easily the stand up on end.
The only thing that made me give them 4 stars instead of 5 was that top flap is kind of tall and it has taken some adjusting to figure out how to pour the milk in without the flaps getting in the way and making me spill milk...which is very upsetting!! Breast milk is GOLD, and I do cry over spilled breast milk! But I have learned to just flip the flaps down before I pour and that seems to have solved that problem. :)
4 Stars By Karleigh on 2017-07-03 I like these bags well enough I like these bags well enough. Out of my last 100 count, I only had a few leaks, so overall not bad. These are the bags that you can pump directly into (with an adaptor), so that is convenient. Out of all the milk bags I have tried, I prefer these the best. They are strong and durable. These same bags/same amount were twice as much at my local Target (these are even a lot cheaper than at Walmart!). The 100 count is really a good price point! I also have the pump & save adapter from the medela brand pump & save bags, and I have used that adapter to pump into these bags (before I had the recommended Lansinoh adapter) by cutting a small slice with a box cutter...it worked well, and saved washing bottles....although the adapter is fairly inexpensive! Happy pumping!
2 Stars By Maritess G. Pajarillo on 2017-03-22 Leaky bags! I used these bags 2 years ago and they were great. I don't know what happened with the new design but I'm running into issues with leakage. I can't even explain how frustrating it is to lose milk because half the bag leaked in the fridge. I bought a bunch of these bags so now I'm adding a small sandwich bag under so I can find it a bag is leaking. I'm hoping to find a better storage bag in the meantime.
1 Stars By Anthony M. on 2015-08-30 Bags Leak after Freezing My wife stored all of her milk in these with our second child, and almost ever other bag has leaked after they were frozen. We have lost so much breast milk it isn't funny. I'm sure every parent knows this stuff is "liquid gold". We opted for these bags because they were more cost effective than the Ameda bags we used with our first.
