Chris Pratt doesn't just consider himself a proud father — he's a lucky one, too. When he and wife Anna Faris welcomed son Jack to the world, it was touch and go following the premature birth.

On Thursday, the actor shared a sweet video of their now-thriving boy on Instagram, as well as a very important message.

In the clip, Jack is mesmerized by a praying mantis that hitched a ride on his arm, and in the caption, Pratt explained why that moment and every other one with the adorable little guy is so precious to him.

"As many of you may know, our son Jack was just over 3 pounds when he was born," the "Guardians of the Galaxy" star wrote. "Thanks to scientific advances made possible by March of Dimes funding, today he's a perfectly healthy, curious 4-year-old."

Pratt penned the message for World Prematurity Day, which is meant to bring attention to the leading cause of death for children under 5 years old.

"Fifteen million babies are born prematurely each year around the world. And 1 million of them won’t live to celebrate their 1st birthday," he continued. "The March of Dimes strives for a world where every baby has a fair chance, yet this is not the reality for many mothers and babies."

The actor then invited his followers to join him in supporting the March of Dimes.

In 2014, Pratt appeared at a March of Dime benefit and spoke about the ultimate reward after Jack's birth.

"I've done all kinds of cool things as an actor — I've jumped out of helicopters and done some daring stunts and played baseball in a professional stadium, but none of it means anything compared to being somebody's daddy," he said.
