Pampers is introducing what it's callingthe world’s tiniest diaper, Swaddlers size ”Preemie extra extra small” (Pxxs). Designed for the extremely premature skin of babies born as early as 21-22 weeks or weighing less than 500g, the handcrafted diaper is made with soft materials.

“Working in the NICU for over 25 years, I have experience with the challenges involved in caring for premature infants. The Swaddlers Pxxs diapers are a vital innovation, offering a fit and softness in such a small size that we haven't seen before. They truly meet the specific needs of our tiny patients, giving us peace of mind that we are offering the highest level of care," said Johni Cochran, MSN, NNP-BC at Cincinnati Children’s Hospital.

In 2025, the national preterm birth rate was 10.4%, representing more than 360,000 babies and their families.

Pampers Swaddlers size Pxxs will be available at a select group of hospitals in 2025 and will continue to roll out nationwide. The Pxxs will not be sold in retail stores or online as they are handcrafted and uniquely designed to meet the needs of premature babies in the NICU.
