Baby dons tiny cap and gown as he 'graduates' from NICU

A video has gone viral of a baby boy graduating from the NICU at an Alabama hospital. 

Cullen was born at just 22 weeks and two days, weighing a little less than 14 ounces. 

His parents said they were told their baby boy had a 2% chance of survival and would be disabled if he did live. 

After spending 160 days in the Children's and Women's Hospital in Mobile, Cullen now weights 5 pounds and 11 ounces, and he has been discharged from the hospital!

The hospital shared a video of his "graduation ceremony" on Facebook. The clip has been melting the hearts of millions on the internet.
