It started on Friday, Oct. 13, and concluded with a near photo finish the next day.

Viviana Cueva Gomez, who was getting close to her due date, went to St. Charles Hospital with her husband Bryan at around 7 p.m., when she started to feel discomfort.

The medical staff admitted her to the hospital, where she and Bryan anticipated the delivery of their first child.

Around 3 a.m. on the 14th, Anita Gomez, who is married to Viviana’s brother and was also pregnant, began to experience contractions, which sent her to Port Jefferson-based St. Charles Hospital as well.

At one point during the night, Viviana suspected that her sister-in-law was at the hospital.

Viviana asked the hospital staff if they could confirm that Anita was on the same floor.

The hospital, however, couldn’t give her that information because of confidentiality rules.

At some point during the next day, Viviana’s husband Bryan bumped into his brother-in-law Byron.

“I didn’t know my sister was there,” said Byron. “When I saw Bryan, we were joking” about how their sons were coming on the same day.

Indeed, as that Saturday wore on, Dr. Sarah Karalitzky performed C sections on both women.

Despite coming to the hospital second, Anita won the birth race, delivering her son Thiago at 4:26 p.m., while Viviana gave birth to Mattias soon thereafter, at 5:45 pm.

Separated by just over an hour with their birth times, the cousins were also just over half a pound different in weight: Thiago weighed in at 8 pounds, one ounce, while Mattias was 7 pounds, 10 ounces.

Big announcements

The extended family work in the same business, towing and fixing cars at S&B Auto Repair in Middle Island.

Viviana recalls the moment her brother shared the big news with their father Secundo at work.

Byron “started to tell my dad,” she said. “Everyone asks him what happened, is someone here [having] a baby?”

The family looked at Anita, who also works at S&B.

“Yes,” Byron said, “but someone else is, too.”

Their father looked at his daughter.

“Viviana, you?” he asked.

When she nodded, he jumped up and clapped for the impending arrival of two grandchildren.

“We didn’t believe we would deliver the same day, but things happen,” Viviana said.

Viviana, 31, and Byron, 29, have two other siblings, neither of whom is married and has children.

In addition to this momentous day, the extended Gomez family, who are originally from Ecuador, is having a memorable year, with a cousin giving birth this past June while another cousin is expecting a child in January.

“My family is growing a lot this year,” said Viviana, who lives in Medford.

Expectations for the cousins

Byron and Viviana anticipate that the two cousins, who were born one room apart at St. Charles Hospital and who each left the hospital the following Tuesday, Oct. 17, will be close.

“They’re going to be like brothers,” predicted Byron, who lives in Coram.

The two families haven’t yet decided whether they would consider having joint birthday parties for the Libras, whose Zodiac sign is, perhaps fittingly, represented by two equal parts of a scale.

A friend suggested the two cousins “don’t have to share the same day” for future birthday celebrations, said Viviana. Their friend wants to “go to two different parties” to celebrate each of their births.

A beaming brother

Thiago’s brother Dereck, who just turned five, is already fond of his younger sibling.

“He says he’s going to share TV and toys with him,” said his father Byron. “All the time, he’s kissing him. He really loves him.”

Indeed, Dereck used to play with a friend, but he only wants to be with his younger brother. When Dereck speaks to Thiago, he tells him he loves him and asks his father to translate his newborn brother’s movements and sounds.

“I say that he loves you, too,” said Byron.

Karalitzky, who delivered both babies, said staff members were caught up in the excitement.

An OB-GYN, Karalitzky feels “lucky to be in a field where the vast majority of the time, she’s able to be a part of good news and a happy day” in people’s lives. For the extended family, the shared birthday ensures that people “will always remember your birthday.”

Karalitzky, who has been at St. Charles Hospital for 10 years, should know: she was born on her mother’s birthday.

Her mom “always made it a special day,” Karalitzky said. “Every year, she’d say, ‘This is the best birthday present ever.’”
