A baby is considered fully developed and full-term at 39 weeks of gestation. A baby can be born anywhere between 37 and 42 weeks and can still be considered full-term. This period helps in baby's organ development like brain, lungs, and liver. It also reduces baby's health risks, promotes a better brain development and helps with other cognitive activities. However, under certain circumstances, premature babies are also born. However, when a baby is born at 24 weeks or later, the baby has chance to survival and this chance increases with each additional week of gestation. However, babies who are born before 24 weeks face a high risk of mortality and potential long-term health issues. A baby born before 22 weeks has a survival rate of 6%. So if a baby born in 21 weeks survives, it is no less than a miracle. This is the story of one such miracle that happened where a baby, who had less than 1% chance of survival is now thriving and has broken the world record. "Defied All Scientific Odds"This is from the year 2020 when at 21 weeks, in Alabama, the most premature baby in the world, as per the Guinness World Records, was born.Curtis Means and his twin sister, C'Asya Means, were born on July 5, 2020, at the University of Alabama at Birmingham (UAB) Hospital. Delivered at just 21 weeks and 1 day of gestation—132 days premature—the twins faced overwhelming odds, with UAB estimating their chance of survival at less than 1%. According to Guinness World Records, they were born nearly 19 weeks early."Numbers show that babies born so young have little to no chances of survival," said Dr. Brian Sims, a professor of pediatrics at the UAB who was the on-call physician when the twins' mother, Michelle Butler. The doctor's statement is part of UAB's official statement. However, C'Asya did not respond to treatment and died the day after birth, but Curtis' heart rate and oxygen levels started to improve."We have never been able to bring a baby that young to the neonatal intensive care unit, so [Curtis] was literally the first of his kind," Sims told Guinness World Records. We were in uncharted territory." Curtis received constant medical care that helped him breathe. His body temperature was also regulated and other care, including enough nutrition intakes were maintained. It was in about three months, when the doctors were finally able to take him off a ventilator. Dr Colm Travers, an assistant professor in the Division of Neonatology said in a statement, "Curtis defied all scientific odds." Indeed he did. Age and birth weight are two of the most important factors in determining a newborn’s chances of survival, he explained. The odds are also higher if the baby is female, not part of a multiple birth, and if the mother received steroids before delivery to aid lung development—none of which applied in Curtis’s case. Yet, Curtis survived. How The Baby SurvivedAt birth, Curtis weighed just 14.8 ounces (420 grams)—roughly one-seventh the weight of an average full-term newborn, according to Guinness World Records. Despite the odds, he grew stronger each day and was discharged from the hospital around nine months later, supported by medication, a feeding tube, and bottled oxygen.After celebrating his first birthday, Curtis—affectionately nicknamed "Poodie" by his family—was officially recognized by Guinness World Records as the most premature surviving baby.Six months after his discharge, Curtis’ medical team gathered outside the University of Alabama at Birmingham hospital to surprise his mother with the Guinness World Record certificate. The previous record holder, Richard Hutchinson, had been born just a month earlier, on June 5, 2020, at 21 weeks and 2 days.
