DELANO, Calif. (KBAK/KBFX) - What are the chances of having twins born in different years?

"It's pretty unusual. I would say it's pretty rare," Doctor Seyed Tamjidi said. "I've been doing this for 35 years and I've never had this before."

Tamjidi delivered a set of twins at Delano Regional Medical Center on New Year's Eve and New Year's Day. He said that has not happened for as long as he can remember.

Hospital staff said in Kern County the boy was the last baby born in 2017, and his twin sister was the first baby born in 2018.

Joaquin Jr. Ontiveros was born Dec. 31, 2017, at 11:58 p.m. He is 18 inches long and weighs 5 pounds, 9 ounces.

Aitana de Jesus Ontiveros was born Jan. 1, 2018, at 12:16 a.m. She is 16 1/2 inches long and weighs 4 pounds, 10 ounces.

The mother, Maria Esperanza Flores Rios, said it was a high-risk pregnancy so she feels blessed both babies are healthy.

Her due date was Jan. 27, but she had a c-section scheduled for Jan. 10.

The parents said they are overjoyed with the early surprise.

Every year the hospital collects donations to shower the first baby born in the new year with gifts.

Matthew Cauthron, marketing director at Delano Regional Medical Center, said the twins will go home with more than $3,000 worth of baby supplies.

"It's a good way to start the new year," Cauthron said.
