DINWIDDIE COUNTY, Va. – A baby boy given a 5 percent chance of survival is celebrating his first birthday.

Kaleb Arkell Graves was a viral sensation before he was even born. Mom Dana Griffin-Graves shared a video of her husband, Arkell Graves, weeping openly when he realized she was pregnant. She placed a pack of buns in the oven to break the news to him, earning baby Kaleb the nickname “Baby Buns.”

The couple had been trying to conceive for 17 years, suffering several miscarriage and a stillbirth. The pregnancy came as a big surprise, but they were thrilled to be welcoming a son.

On October 20, 2015, baby Kaleb arrived 16 weeks early. His parents say doctors gave him a 5 percent chance of survival. Early photos show Kaleb resting in the palm of a nurse’s hand.

After spending 356 days growing stronger in the NICU at Virginia Commonwealth University Hospital, Kaleb was finally able to go home. Friends and family decorated the Graves’ home with balloons and banners to mark the momentous day.

“At this very moment, all of my men are asleep under the same roof,” Dana wrote on Facebook the day after his homecoming. “Some days I really didn’t think that would happen.”

Kaleb still requires medical care at home, but the family hopes it’s only temporary.
