Premature babies dressed up for Christmas at UNC Health Rex and Cape Fear Valley Health

RALEIGH, N.C. (WTVD) -- It's a tradition that never gets old: dressing up premature infants in holiday appropriate costumes!

Today's installment includes babies at the neonatal intensive care unit at UNC Health Rex in Raleigh as well as Cape Fear Valley Health in Fayetteville.

In Raleigh, Buddy the Elf made a surprise visit to the hospital and helped spread Christmas cheer (by singing loudly for all to hear, probably) for the NICU parents and staff.

In Fayetteville, the Grinch came down from Mt. Crumpet to greet the newest little humans (or WHOmans).

These little ones are all definitely on Santa's Nice List.
