We're sorry to hear your kiddo went through that, and we hope your baby is feeling better now! Please be assured that our Luvs Platinum Protection diapers are safe. They have the same safe and mild ingredients as our previous Luvs diapers and should not cause babies to have diaper rash. Our most recent changes include bigger and stronger tapes for improved fit, bigger sides with more coverage, and more fastening area for improved fit. We partner with leading pediatricians, pediatric dermatologists, and safety experts to confirm the materials we use in our diapers are safe for babies. Before any baby uses our products, we conduct a detailed safety assessment, as well as ongoing checks during production, to ensure our highest safety standards are met, so we'd like to learn more to see how we can help further and share this with our team. When you can, please give us a call at 1-800-632-7435.
