Children's Hospital in Chicago holding costume contest for NICU babies

CHICAGO (CBS) — Even the tiniest of humans are getting their chance to celebrate Halloween.

They may be too small right now to go trick-or-treating or even eat some candy, but the babies in the Neonatal Intensive Care Unit (NICU) at Advocate Children’s Hospitals, in Oak Lawn and Park Ridge, participated Tuesday in the hospitals’ annual costume contest.

The parents of the NICU babies were invited to dress their infant in a costume as simple or elaborate as they like. And let’s just say they were super cute and creative!

As a bonus, the hospital is running a Facebook contest. People are asked to vote for their favorite costume by liking their favorite photo on the Adovcate Children’s Hospital Facebook page (and yes you can vote/like more than one) and help families win various prizes until noon on Halloween – Oct. 31.

The photo/baby with the most votes by Halloween will receive a $150 gift card to Babies R Us. Five runner-ups will take home gift cards ranging in value from $25-50.
