So, the staff at the hospital decided to host a graduation ceremony for him, complete with a tiny cap and gown.
Since Cullen was so small, weighing nearly 6 pounds, his mother, Molli Potter, bought the graduation gear from a nearby Build-A-Bear store, ABC News reports.
"We were (at Build-A-Bear) with our older son and my wife was looking and thought it would fit Cullen," said Cullen's father, Robert Potter. "The hat was actually a little big."
On his big day, staffers donned Cullen with the cap and gown and, a nurse carried him ceremoniously through a hospital hallway as graduation music played in the background.
The sweet moment was shared on Facebook and has since gone viral.
