World’s most premature baby celebrates first birthday

Nash Keen, born at exactly 21 weeks, 133 days ahead of his mother’s due date, has been recognized by Guinness World Records

An Iowa toddler who was born when his mother was less than five months pregnant isn’t only the most premature baby recognized by Guinness World Records after recently turning one.

As his mother, Mollie Keen, put it, Nash Keen is also “very determined, curious … and he’s just all smiles all the time” after surviving against what Guinness described as “phenomenal odds”.
