Nothing is more important to us than the health and safety of our little Pampers users. We’re sincerely sorry to hear this happened. Please know that a great deal of work goes into the development and testing of all our products to ensure they are safe for babies. We have careful and thorough procedures in place to ensure this. We work with parents and partner with leading professionals including pediatricians, pediatric dermatologists, and safety experts through every step of the manufacturing process, so we want to assure you that this isn’t something we expect. If your baby is close to the upper end of the weight range for their diaper size, marks around the waist could indicate that your baby is ready to move to the next size. Still, this is not the experience we want for you or your little one, and we’d love an opportunity to help. When you have a moment, please give us a call at 1-800-726-7377.
