A woman delivered sextuplets at a Houston hospital Friday morning, giving birth to all six babies within nine minutes.
Thelma Chiaka gave birth to two daughters and four sons between 4:50 and 4:59 a.m. Friday at the Woman's Hospital of Texas, the hospital announced on its website.
All six of the babies were sets of twins, with two male pairs and one female pair born.
The smallest baby weighed 1 pound and 12 ounces, and the largest was 2 pounds and 14 ounces. The hospital stated that all of the children were stable and being treated in the facility's advanced neonatal intensive care unit as of Friday.
Hours after their birth, Chiaka named her daughters Zina and Zuriel.
The odds of birthing sextuplets are about 1 in 4.7 billion, the hospital said.
