Hello Hua, thank you for sharing this feedback on our Stay Dry Disposable Nursing Pads. We're sorry to hear that you weren't fully satisfied with them. For the best performance, we recommend placing the pads in your bra with the contoured edges to the sides, changing frequently, and using the adhesive tabs to keep them in place. Having said that, we'd like to learn more about your experience. 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 thing right.
