It’s her labor of love.

A woman from North Carolina received an outpouring of love and support from a group of mothers in New York City after going into premature labor during a work trip. In a heartwarming turn of events, she decided to pay forward the kindness by pursuing a career as a labor and delivery nurse.

Former cosmetics saleswoman Shelcie Holbert shared with The Post that her experience in New York City led her to become a nurse. She started her new role just four weeks before Mother’s Day.

Holbert was only 23 and six months pregnant when she visited New York in June 2018 for what was supposed to be a three-day business trip.

But on the first day, she rushed to the emergency room with pressure in her abdomen.

During her business trip, Holbert was transferred to Mount Sinai West, a hospital known for handling premature labor cases. A week after her arrival, she gave birth to her daughter, Rosalie Grace, who weighed only 1 pound and 9 ounces at birth, fighting for her life.

She spent three harrowing months with her daughter in the neonatal intensive care, watching her struggle to survive.

“It gave me a whole new outlook on life,” Holbert said.

When other moms there learned about Holbert and her husband Jacob Wallace, who who had no family in New York City, they offered them a place to stay, dinners, gift cards and new clothes.

“I felt like I could never repay the people who donated to us, or shared our story or cared,” said Holbert.

“What could I do to kind of balance the scales a bit and show them, ‘I am really grateful for what you did’ — other than become a nurse?”

Holbert has been assisting with Caesarean sections at Atrium Health in Charlotte, NC.

“I love it,” she said. “I want to be able to advocate for women and children.”

Her path from skin care to scrubs was anything but straightforward.

“It took me some time to finish [nursing school] because being a mom and going to school, it’s not the easiest thing ever,” she said with a laugh.

Her time in the city that never sleeps paid off.

“Being in the NICU like that for hours and hours and hours, for months, I can’t even explain to you how much that put me ahead in school,” she said.

Rosalie is now an energetic 6-year-old — and big sister to younger siblings Noah, 4, and Chloe, 2.

“I learned what went wrong for me with Rosalie,” said Holbert, who explained a weak cervix contributed to the early labor in her first pregnancy, while a procedure called a cervical cerclage, in which the cervix is stitched closed, allowed her to carry her subsequent children to term.

Now a single mom, Holbert and Rosalie visit New York and the lifelong friends they have there about once a year.

“She loves to go back to New York,” Holbert said of her oldest. “I want my daughter to know where she’s from. She’s very proud of where she’s from.

“She tells me she wants to be a baby doctor, she wants to do surgeries,” the proud mom said.

“I’m constantly extremely thankful for everything and that would not have been possible if people did not care.”
