Hello Randy, thank you for sharing this feedback on our Breastmilk Storage Bags. We're sorry to hear about your experience. Our bags are formed from a premium monolayer film that allows them to be both strong and flexible. As such, we do recommend supporting them at the top and bottom when pouring, as well as supporting them with a hand or placing them into a glass when being poured into. They should be supported until sealed. Having said that, we'd like to learn more. Please reach out directly at wecare@lansinoh.com, and a member of our Consumer Affairs team will get back to you right away. We look forward to hearing from you and making things right.
