## Description

Product Description

Review: Great. - Strong bags, easy to use, double zip lock, good size for freezer, accurate measurements. Good value
Review: Breadtmilk storage bag - I’ve been using the Lansinoh breast milk storage bags for a few weeks now, and they’ve made my pumping routine so much easier. The bags come pre-sterilised, which is super convenient, and I feel confident using them straight out of the box without any extra steps. The double zipper seal is very secure—I’ve had no leaks, even when freezing and thawing. I also love that the bags can lie flat in the freezer to save space, or stand upright in the fridge when needed. The labeling area is easy to write on, and the measurements are fairly accurate for tracking volume. So far, I’ve had no issues with durability or tearing, even when opening the bags with slightly wet hands. They’re also BPA and BPS-free, which gives peace of mind. These are now a staple in my daily routine. Highly recommend for any breastfeeding or pumping parent.

## Questions & Answers

**Q: Can you pump directly into these bags? It's unclear if there are the correct bags or not**
A: Yes. You can just attach them to the pump and pump directly.

**Q: is it pre-sterilised?**
A: Yes they are pre-sterilised which is the great thing about them.

**Q: After baby is 6 months old can you open packet from freezer, squeeze out how much you went to defrost and put the packed back I the freezer?**
A: I don’t know about squeezing out but I use the bags to freeze smaller portions of 2oz then defrost and use immediately so I don’t waste a full bag if not needing the full amount.

**Q: Can I collect the milk in one bag throughout the day by keeping in the fridge and then freeze it?**
A: This was my daughter, not me, but since she lived with us a lot after the baby was born, as I remember it…. one bag is really only big enough for one pumping session when the baby is older. If you have less milk (e.g. when the baby is smaller there’s less), she used to top up one bag sometimes from the very next feed. But the milk you use to top up needs to be completely cooled in the fridge before adding it to existing milk. There’s quite a lot online about this so double check your particular method to be sure.

### ⭐⭐⭐⭐⭐ A Lifesaver for Nursing Moms: Durable and Convenient Lansinoh Breast Milk Storage Bags
*by M***S on 12 July 2024*

The Lansinoh Breast Milk Storage Bags have been an absolute lifesaver for me! As a nursing mom, I need reliable and convenient solutions for storing breast milk, and these bags deliver on all fronts. First, the quality of these storage bags is outstanding. They are incredibly durable, made from thick plastic that doesn't tear or leak. I've never had to worry about spills or losing precious breast milk, which is a huge relief. The design is also very user-friendly. The bags come pre-sterilized and are easy to fill and seal. The double-sealed zipper ensures that the milk stays fresh and secure. I also love the pour spout feature, which makes transferring milk to a bottle simple and mess-free. Another great feature is the space for labeling. The bags have a convenient area to write the date and amount of milk, which helps keep everything organized in the fridge or freezer. This is especially helpful for managing milk rotation and ensuring that the oldest milk is used first. Overall, the Lansinoh Breast Milk Storage Bags have exceeded my expectations. They offer excellent quality, ease of use, and reliability. I highly recommend them to any breastfeeding mom looking for a trustworthy storage solution for their breast milk.
