While Nov. 17 was probably a regular Thursday for a lot of people, it was actually a day very close to Chris Pratt's heart. The proud family man [2], who welcomed son Jack [3] in August 2012 with wife Anna Faris [4], posted an adorable video on Instagram on Thursday in honor of World Premature Day. In the clip, 4-year-old Jack is seen playing with a praying mantis and giggling about what to name his new friend. While Jack was less than four pounds when he was born premature, he's now a healthy and happy little boy, which is a possibility the Passengers [5] actor wants to give other families going through the same thing. He captioned the sweet video of Jack:
"As many of you may know, our son Jack was just over 3 pounds when he was born. Thanks to scientific advances made possible by #marchofdimes funding, today he's a perfectly healthy, curious 4 year old. Today is #worldprematurityday. 15 million babies are born #prematurely each year around the world. And 1 million of them won't live to celebrate their 1st #birthday. The @marchofdimes strives for a world where every #baby has a fair chance, yet this is not the reality for many mothers and babies.
