Hello Amanda. We can definitely understand how frustrating this would be and we’re very sorry the bags leaked! We would greatly appreciate it if you could reach out to our consumer affairs team at 800-292-4794 or firstname.lastname@example.org. We would love to get the lot information from the bags you experienced an issue with and do what we can to help make this right for you. We are constantly testing and improving our bags, and feedback from moms like you really does help improve even further. In just the past year we have made upgrades to our production process to ensure this issue never happens again. We hope to hear back from you and thank you again for this feedback.
