Chris Pratt posts adorable video of son in honor of World Prematurity Day

Chris Pratt shared a video of his and Anna Faris' adorable son, Jack, with a very important message in honor of World Prematurity Day on Thursday, Nov. 17.

The actor shared the video of their 4-year-old to raise awareness of preterm birth which is something very close to his heart since Jack was born nine weeks premature.

“As many of you may know, our son Jack was just over 3 pounds when he was born,” the 37-year-old dad wrote. “Thanks to scientific advances made possible by #marchofdimes funding, today he’s a perfectly healthy, curious 4 year old.”

Pratt went on to provide statistics of how many babies are born prematurely every year and what their survival rate is.

In the video, Jack is all smiles with a praying mantis on his arm as Pratt asks him what the insect's name is going to be.

We dare you to watch this and not smile:
