DINWIDDIE COUNTY, Va. -- The announcement of his "miracle conception" went viral on social media. His actual birth, 16 weeks before his scheduled due date, was shared and reported by news outlets around the world. This week Kaleb "Baby Bun" Arkell Graves turned two weeks old in the hospital.

To mark the milestone, Kaleb's mother shared video of her singing to her newborn son.

"Today I am rejoicing because Kaleb is 2 weeks old!!" Dana Griffin-Graves posted on Facebook. "I sing this to him daily but today we recorded it. God bless and I love and appreciate you all so much. Thanks for encouraging me daily."

The couple made international headlines in October when they posted their emotional pregnancy video online. Dana said she and her husband started trying to have kids after they got married 17 years ago,  but gave up after delivering a stillborn baby at six months and four miscarriages.

While the couple adopted son Keelyn, who they recently referred to as their first miracle, they believed they would never have a biological child of their own.

As time passed and their hearts began to heal, Dana recently started walking with her friends, but she wasn’t losing weight like they were. So she went to the doctor. That’s when she found out she was five months pregnant.

“I was ecstatic,” she said. “We hadn’t planned anything, we weren’t trying.”

So she started thinking of a way to surprise her husband with the news. The mommy-to-be put literal buns in the oven, and next to the buns, she placed a sonogram picture. When Arkell realized he’s going to be a dad, his reaction was perfect.
