In a remarkable medical milestone, a baby boy named Nash Keen has been recognized as the world’s most premature baby by Guinness World Records. Born on July 5, 2024, in Iowa City, Iowa, Nash arrived at just 21 weeks of gestation, weighing a mere 10 ounces. This extraordinary birth occurred 133 days before his expected due date, surpassing the previous record set in Alabama in 2020 by just one day.
Nash’s early arrival was unexpected, following a routine 20-week prenatal checkup where his mother, Mollie Keen, discovered she was already 2 centimeters dilated. Days later, she went into labor. The initial days were filled with fear and uncertainty as Nash was surrounded by medical equipment and a dedicated team fighting for his survival. Despite the overwhelming circumstances, Mollie found solace in the strength her son exhibited from the very beginning.
After spending six months in the neonatal intensive care unit at the University of Iowa Health Care Stead Family Children’s Hospital, Nash was finally able to go home with his parents in January 2025. His journey has been one of resilience and triumph over adversity. Although he still requires some medical assistance, including oxygen support and a feeding tube, Nash continues to grow stronger each day.
Nash’s story has resonated with many, making him a local celebrity and touching hearts across the nation. His mother describes him as not only a record breaker but also a heart-stealer. The community’s support has been invaluable to the Keen family as they navigate this unique journey.
As Nash continues to develop, he attends specialized medical daycare where he receives necessary therapies. Regular check-ups with his care team ensure that he is progressing well. His story is one of hope and perseverance, inspiring many who hear about his incredible journey.
