World’s most premature surviving baby continues to reach new milestones, inspire others

IOWA CITY, Iowa (KCRG/Gray News) - The world’s most premature surviving baby, Nash Keen, continues to reach new milestones while giving hope to families of the tiniest newborns.

Last week, it was reported that Nash’s survival is helping shape care for babies born at 21 weeks gestation.

Now, his mother, Mollie Keen, says his journey continues to inspire parents navigating similar circumstances.

Researchers at the University of Iowa Health Care recently shared that six out of 17 babies born at 21 weeks gestation at the hospital between 2010 and early 2025 survived to be discharged.

Doctors added that those outcomes reflect advances in neonatal care for babies once considered too premature to survive.

“I love that Nash is paving the way for more babies to be saved. I’ve heard from so many 21-22 week moms who have reached out to me for support,” Mollie Keen said.

Nash, who was born 133 days premature, continues to make steady progress at home while participating in physical, occupational and speech therapy.

Mollie Keen said her baby boy is crawling, sitting up on his own and expanding his vocabulary.

Nash does use a feeding tube and receives oxygen while sleeping after experiencing recent respiratory illnesses, but his mother says he has also begun to feed himself.

“Nash is giving them hope,” Nash’s mother said. “That means more to me than anything.”

Mollie Keen said watching her son reach new milestones has been incredibly rewarding. She hopes his story continues to encourage families facing similar challenges and show them that survival is possible.
