Tiny patients in a neonatal intensive care unit have donned their spookiest outfits for Halloween.

The premature and poorly babies - who are in the Cleveland Clinic Children's NICU - got into the Halloween spirit by dressing as a ladybug, boxer and cheerleader for the celebration.

Other tots in the unit wore outfits such as a penguin, a football, a skeleton and Sully from Monsters Inc. to celebrate the spooky season.

The miniature costumes were donated - some outfits were even crocheted outfits by NICU caregivers while others were brought in by parents.

Julie Gamary, NICU nurse manager, said: "Dressing our babies in costumes brings moments of connection to families during what can be an uncertain time. "

"It's a small gesture that helps families celebrate milestones and create special memories, even in the hospital setting. "

"During what can be an emotional time for our families, we hope this fun event brings them joy. "

"We'd say Halloween couldn't be sweeter."
