WATCH: Eric Hart posted a video of the costume-making process on YouTube. In the first week it has collected nearly a half million views.

TORONTO – A video of a premature baby in hospital has gone viral after his father created and dressed him in an Iron Man suit for his first Halloween.

Eric Hart is a prop-maker and author of “The Prop Building Guidebook: For Theatre, Film, and TV”. His son, Collier, was born premature and has spent all of his four months of life stuck in hospital connected to machines.

With Collier’s first Halloween on its way, the Burlington, North Carolina native decided his son would put on a brave face.

“Collier’s hooked up to the machines all the time and Iron Man, he built the suit because he needed a machine to keep himself alive,” he told Right This Minute.

“I just thought if he had a little Iron Man suit he could come home with us.”

Hart set to work on creating a foam Iron Man costume in the image of Robert Downey Jr.’s box-office smash hit Marvel Comics series.

Just before midnight on Halloween, Hart tweeted a picture of his son wearing the outfit.

“My baby has the best Halloween costume in the intensive care nursery,” Hart said.

Four days later, Hart published a video of the entire process on YouTube and it didn’t take long to go viral. After one week, the video has been viewed almost 450,000 times.

On Tuesday morning, Hart tweeted he’s received more requests to see the pint-sized superhero suit.

Last night at rounds, the doctors asked when they could see Collier in his Iron Man suit again,” Hart said in a Tweet. “They thought it was adorable.”
