LansinohBreast Milk Storage Bags - Pre-Sterilised, Leakproof & BPA/BPS-Free - Fridge & Freezer Breastmilk Pouches - Pump into bag with Lansinoh Breast Pumps - Breastfeeding Essentials - 25 Pack

I started buying these milk storage bags in order to freeze any extra milk I expressed once I'd filled up all the storage bottles I had space for in the fridge.The bags are a good quality thick plastic and have a double seal at the top. There is an area at the top to write notes on when it was expressed, the amount of milk etc, this can be written on easily with just a biro. Each bag has a tear off area at the top so that you know the bag is new and hasn't been tampered with.In the time that I fed my first child I filled around 50 of these storage bags and I never had a single one that leaked. I always made sure to store a few of these bags frozen flat together inside a large ziplock bag or box to stop them catching against other stuff in the freezer. The shape of the bag also makes it easy to pour the milk into a bottle without spilling.I would say however that you can't rely on the markings on the side of the bag to accurately fill them with a specific volume of milk. I tend to fill up these bags on the scales to make sure I'm pouring in the correct amount.It is also worth testing your baby to see if he will drink milk that has previously been frozen before committing to buying large quantities of these bags. Defrosted milk can have a soapy smell, so some babies won't touch it. My daughter would drink it but I noticed that she was less keen on it and was more likely not to finish the bottle if I was giving her milk that had been in the freezer.Overall these are an excellent product and I am sticking with these storage bags now that I am breastfeeding my second child.

Brilliant bags to store as and freeze milk

These storage bags are very convenient for keeping breast milk safe and organized. They’re easy to fill, seal, and store in the fridge or freezer. I like the clear measurement markings and the sturdy material. Perfect for parents who pump regularly.Pros: Easy to use, clear measurements, durableCons: None so far

Really good quality, easy to use, can even pump straight into them which is handy! They have a double seal which is great and the instructions are simple and easy to understand

Really good quality, comes in a sealed zippy bag for ease. These are super easy to use and no leakage.

I’ve never had an issue with the storage bags. They hold well, freeze well flat and are otherwise good for storing breastmilk.Negatives: they’re hard to ziplock up with all air removed, I’ve always got an air pocket in the bag.

Bought these to store my left over expressed milk in the freezer. If you freeze them laying flat they freeze into space saving blocks so don't take up your whole freezer! Easy to zip up even one handed with the baby in the other. Cost is good in comparison to others and made of safe materials. 🙌

Good bags so far no leaks and found this pack of 25 to be better value than the larger packs, plus I probably won’t use more than 25! They don’t have as capacity as some of the other brands and don’t have the pouring spout but don’t know if this will be an issue until I defrost my milk in months to come
