LOUISVILLE, Ky. (WDRB) -- Even the tiniest of babies can get in on some Halloween fun. 

Norton Women & Children's Hospital is carrying on its tradition of dressing up some of the little ones in the Neonatal Intensive Care Unit (NICU) for the holiday. 

Among the costumes this year are one little girl dressed as Anna from "Frozen." She even has a wig of braided yarn to complete her look. 

Two pairs of twins are in the NICU. One set is dressed as Superman and Supergirl.  The other set of twins is an adorable princess and a tiny NASCAR driver. 

One little girl is very patriotic with a red, white and blue frilly outfit. And there is even a tiny University of Louisville cheerleader with an "L" on her chest.  

And one future trick-or-treater is dressed as Woody from "Toy Story" -- complete with a  cowboy vest. 

Hospital officials say employees and volunteers make some of the costumes.

They say the annual event gives parents a chance to celebrate their babies and feel like they are a part of the "outside world."
