Can these be used for any pumps?
Best Answer: These can be used with most pumps, but you'll need a Lansinoh Pump Adapter if you're using a Medela, Evenflo, or Ameda pump. For Lansinoh, Spectra, or Motif pumps, no adapter is needed.
What are the dimensions?
Best Answer: These milk storage bags have dimensions of 4.25 inches wide by 6 inches high.
How do you pump straight into the bags?
Best Answer: Simply slide the bag over the Breast Flange Body to start pumping directly into it. For compatibility with other major pump brands, use the pump-into-bag adapter which can be sold separately.
Will insurance cover these? I see on other sites they do?
Best Answer: Check out Babylist.com/heath to see if your insurance is covered.
Do they work with a manual breast pump?
Best Answer: These work with a manual breast pump. You may need to buy an adapter though.
Are these storage bags phthalate-free?
Best Answer: Totally! Lansinoh Milk Storage Bags are BPA, BPS, and Phthalate free.
Are these safe to heat using a warmer from being frozen?

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.

Wanted to love but not the case
I bought these a week ago and I have already had milk spill 3 times they do not hold up for a second. It’s truly annoying

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!!!
