Every year, Christus Spohn South Hospital throws a special Halloween party.
The hospital's Neonatal Intensive Care Unit or NICU threw a reunion party.
It's for kids who were once in the NICU to celebrate with the doctors and nurses who cared for them.
Spohn South's NICU helps newborns who need extra care to stay close to their recovering mothers.
The party draws a huge crowd.
NICU staff tells us it's a great feeling seeing the babies they care for enjoy their childhood.
