Defrosting Issues


I have been using the Lansinoh bags since I started collecting breast milk - starting with 2oz, 4oz, and now 6oz batches. Since going back to work, I have been defrosting them in the refrigerator overnight for the next days bottles. At least a couple times a week, at least 1 out of the 4 bags I defrost has a hole somewhere in the bag and leaks BM all over the refrigerator. I have since started putting the bags in a giant sealed bag as to contain the mess... It seems like such a waste to be using the bags to only have them leak my carefully collected BM all over the place. Has there been any other issues from other Lansinoh bag users? Is there something different you would suggest trying so this issue doesn't continue to happen? Thanks!


I am sorry this has happened to you. There are specifics we can discuss with you though it would be preferable to do this via a phone call so we can discuss particulars. Our customer service number is  800-292-4794.

Best wishes,
