Sarah Herronis mourning the loss of her newborn son who died shortly after she gave birth at 24 weeks pregnant.

“On January 28th, at 24 weeks old, our beautiful son Oliver Brown was born,” she began in the caption. “He passed awayin his dad’s arms shortly after.”

In a touching carousel, Herron shared a photo holding her infant on her chest as her fiancé Dylan Brown kisses her forehead, his hand next to Herron’s.

Her set of images included unforgettable moments from her pregnancy, including swimming with sea turtles, a trip to the beach, and cuddling with her pup. It ends with a picture of Brown kissing Herron’s forehead as she cries in a hospital bed.

“There are no words for the magnitude of loss and pain we’re experiencing. It’s beautiful and simultaneously tragic,” she wrote.

“Oliver, our IVF miracle defied so many odds and fought through so many hard milestones to be here, but the higher powers still had other plans for the three of us,” Herron said.

Herron said though her time carrying Oliver was “short,” she is “grateful” for the time they shared while she was pregnant.

She recalled some of her favorite moments Oliver was present for, stating, “Oliver swam with sea turtles, he kept me company while I recovered from a broken knee, and he loved his dad’s cooking. Most of all, Oliver loved his morning routine of laying heart to heart with his brother, Rio, on my lap.”

Herron went on to say, “While our hearts are shattered beyond comprehension, we are comforted knowing that our son’s soul only ever knew love and will not suffer in a body that wasn’t built for this life.”
