Parents of rare identical quads share their first photoshoot

Mercedes and Jonathan Sandhu, the Texas couple who welcomed identical quadruplets on May 1, have an exciting announcement: All four babies are home!

Hannah Grace, Lucy Marie, Rebecca Claire and Petra Anne have been discharged from Texas Children's Pavilion for Women. They came home last month and the family even made time for a special photo shoot. Their brothers, Luke, 4, and Aaron, 20 months, couldn’t be happier.

“We were so worried about how they were going to react — but our boys love having sisters,” Jonathan, 37, tells TODAY.com. “Every morning, Luke runs downstairs to see the girls. He wants to hold them and help with bottles.”

Jonathan says that Aaron, who will turn 2 in November, “gets worried when he hears the babies cry and will pat their backs gently to try and soothe them.”

“Aaron gets so concerned,” Jonathan shares. “If one of them is crying, he’ll pull us over to their bassinet.”

"Life is good," he adds.

Doctors put the odds of having identical quadruplets at about one in 15 million. There are roughly 72 documented cases of spontaneous identical quadruplets in medical history. Spontaneous means that the babies were conceived without reproductive assistance.

Mercedes previously told TODAY that her third pregnancy came as a surprise.

“We weren’t trying by any means, but we were excited,” she said. “But when we found out there were four … Holy moly!”

"Holy moly!" Jonathan echoed.

With six kids under the age of 4, the Sandhus are having lots of “holy moly” moments.

“It’s an adjustment, you know, we have more babies than we have hands,” Jonathan explains. “So we’re figuring out a schedule on how to feed them, starting with whoever is the hungriest. Then we work our way down.”

To make sure they don’t get the quads mixed up, the Sandhus, who are both engineers, have each bassinet and infant carrier carefully labeled. The girls wear name bands on their wrists.

“They all make little newborn grunts,” Jonathan says. “It sounds like they’re talking to each other. One will grunt, and then another will reply. I’m convinced they’re interacting with each other."

The four girls were delivered via cesarean section at 29 weeks gestation. The smallest was Petra, who weighed in at 2 pounds, 7 ounces; Hannah, the largest, was born at 2 pounds, 13 ounces.

According to Dr. Nathan Sundgren, associate medical director of the neonatal intensive care unit (NICU) who treated the babies, the sisters are now all between 6.5 to 7 pounds, and "doing great."

The Sandhus share updates about their family on their Instagram, The Sandhu Crew. After TODAY.com broke the news about their quads' arrival, the Sandhus heard from people across the country.

('We've) had people reach out with things like 'my daughter was born at 1 lb, 5 oz. She’s 5 feet, 11 inches, and playing D1 volleyball now.' Or “I had quadruplets in 1983. It was scary, it was overwhelming, but it was so, so fun. I’d do it again in a heartbeat,'" Jonathan says. "Things like that were not only inspiring, but it made us think “Hey, we can do this!”
