We're so sorry to hear this, Jennifer, and we hope your kiddo is feeling better. Please know that a great deal of work goes into the development and testing of all our diapers to ensure they're safe for babies, and we know how frustrating leaks can be. It could be that your kiddo would do better in a larger sized diaper, so we'd like to learn more to see how we can help with this and share your experience with our team. When you have a moment, please give us a call at 1-800-632-7435, M-F 9am-6pm EST.
