New breastmilk storage bags
We all know the feeling of spilling even a drop of milk. These new storage bags have spilled my milk twice from a hole at the side of the bags. I literally shes a tear as almost 2 ounces of milk spilled and I didn’t notice it. It’s too plasticy for me. I prefer the old bag way better.

New Design Has Flaws
I LOVED the ones with the blue zipper (I believe that’s the OG design). I recently ordered more and got the new design with the pink zipper and the big Lansinoh logo flower on the center of the bag. This zipper leaks before I even get my milk in the freezer! I wish you’d go back to the stronger zipper if you’re going to change the style of the bag.

Terrible
They’re hard to pour milk into. They don’t stand. One fell out of my fridge due to not being able to stand and got a hole. Thawed a bag of milk and it started leaking.

Favorite and Most Durable Storage Bag
I have used this brand for my breastmilk storage for YEAAARSS. Never have I had an issue with spilled milk or nothing. I’ve kept my breastmilk for up to a year, that I had saved for breastmilk baths for my kids and the bags condition was still excellent. Definitely helps with keeping your milk flat and having enough storage.

The flatest bags to freeze!
I love making frozen milk bricks from these brags, they are the flattest! They make the perfect frozen bricks for deep freezer storage. By far my favorite and they don’t leak!!

NO LEAKS!!
I bought these during pregnancy and so far (3 months in) they are the only bag that hasn’t leaked when thawing! I typically freeze 4-6oz depending and have had absolutely no issues, plus they fit great in my freezer storage container!

THE BEST MILK BAGS
I’ve been using their storage bags since the beginning of my breastfeeding and pumping journey and they truly are my favorite, you’re able to freeze them so thin and they never bust! The best!!!
