PHOENIX -- A Texas couple gave birth to a record-breaking set of quintuplets at Banner Good Samaritan Medical Center in Phoenix on Tuesday, television station KPHO report.

Rachelle Wilkinson, of Cedar Park, Texas, delivered three girls and two boys.

The babies had a total weight of 21 pounds, 7.2 ounces, which is the new U.S. record for quintuplets, according to Dr. John Elliott, Wilkinson's perinatologist. The previous record was set in 2003 by a Pennsylvania woman who also gave birth at Banner Good Samaritan.

Wilkinson and her husband, Jayson, named the girls Kaydence, Kassidy and Kyndall; the boys' names are Rustin and Ryder.

After the birth, four of the infants were being cared for by the Phoenix Children's Hospital's neonatology specialists, while Kassidy was allowed to go to the well-baby nursery at Banner Good Samaritan.

Wilkinson is the sixth woman to give birth to quintuplets at Banner Good Samaritan, which has also seen the deliveries of about 74 sets of quadruplets and two sets of sextuplets -- including one set in July. The hospital said most of the women who gave birth to quadruplets and quintuplets there came to Phoenix from another part of the country.

The Wilkinsons have two other children, Riley, 6, and Kaiya, 4.
