Twins in San Diego are getting some attention because, though born just minutes apart, one has a birthday in 2015 and one in 2016.
Jaelyn Valencia was born New Year's Eve at 11.59pm. Her twin brother, Luis Valencia Jr, arrived at 12.01am on New Year's Day.
KGTV-TV reports that the babies were due at the end of January, but doctors at San Diego Kaiser Permanente Zion Medical Center called the mother in because one was in a breech position.
The father, Luis Valencia, called it a New Year's blessing to have two healthy children.
Although he admitted he had not expected twins.
"I was not really expecting two, so it's a big blessing to have two of them, boy and a girl for New Year's," he said.
Luis said his wife, Maribel, was also surprised.
"[Maribel] really wanted to have the babies on the same birthday because you know later on in the years, they're going to have a little confrontation and be like, 'my birthday came first,' so it means two birthday parties, back to back," he said.
A nurse who helped deliver the twins, Lynnette Coetzee, said the birth is rare.
"It's very unusual and it's very special," she told NBC San Diego. "I haven't seen it in all my 34 years of nursing."
