The siblings were delivered naturally but on either side of midnight as Joaquin arrived on 11:58 pm on December 31, 2017 followed by his twin sister Aitana at 12: 16 am on January 01, 2018. Eighteen minutes later, at 12:16 a.m. Monday, his little sister Aitana entered the world.
Doctors say the baby girl was slightly breached, so she had to be delivered via caesarean section.
In, Fresno, the first baby of the new year was actually born a week late.
A California mother celebrated the new year by welcoming twins: one in 2017, one in 2018. However, at 7 p.m. EST on New Year's Eve, their mother Maria went into premature labor.
Maria Esperanza Flores Rios was originally due on January 27, then had a C-section scheduled for January 10. The babies were said to have born healthy and hassle-free, with only the rarity of their birth timing.
The twins have been gifted over $3,000 of baby supplies by Delano Regional Medical Centre.
Maria Flores' twins were born less than 20 minutes apart.
The twins were also born three weeks early.
"It was definitely a surprise!"
While an incident like this is extremely uncommon, a year ago, four such twin births were recorded in the United States - in Georgia, Utah, Arizona and San Diego in California.
