NASHVILLE, Tenn. - Some of Nashville's smallest superheroes were in town for a big celebration.
Sunday, Saint Thomas Midtown Hospital hosted its annual NICU birthday.
Families of former NICU babies were invited to see the staff again and show them how much they've improved since leaving their care.
This year's theme was "Superheroes." The kids were dressed up in costumes, and some of the staff even got in on the fun.
