They're too young for school, in fact, some of them can't even talk or walk. However, on Sunday, around 370 babies graduated anyway.
The little ones all spent time in the NICU, or Neonatal Intensive Care Unit at College Station Medical Center.
This is the NICU's second graduation celebration in the two-and-a-half years its been open.
"In previous years long before we opened, little bitty babies who had breathing problems or any issues at all that couldn't be managed here were getting transferred out to Houston, Austin, or wherever they needed to go. Now we can do a lot of this stuff here in the community," said Dr. Craig Steiner.
The smallest baby ever at the NICU weighed just over a pound and a half. Doctors and NICU staff say today's graduation was a little like an extended family reunion.
