For those who don't know, Chris Pratt's' son is not just amazing because he's so freakin' adorable.
I mean — he IS freakin' adorable — but he was also born nine weeks prematurely.
If you know anything about premature babies, you know this is a pretty dangerous and often fatal situation for infants.
But Anna Faris and Chris Pratt didn't give up hope, and now their son Jack is a healthy 4-year-old toddler as well as the star of extremely cute photos and videos on Chris Pratt's Instagram.
On Thursday, Pratt continued that adorable tradition, but this time with the intent of raising awareness for World Prematurity Day in addition to spreading the cuteness.
Pratt shared Jack's story on Instagram in honor of the national day and highlighted the charity organization March of Dimes, which is focused on researching ways to prevent birth defects, premature birth and infant mortality.
There's also a video of Jack playing with praying mantis that will warm your heart/make you want to curl up and hide from all bugs ever.
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. Join me in supporting their efforts to give every baby a fighting chance by clicking the link in my bio. Thank you! God Bless!!!
Pratt, who is 37, recently announced he was taking a break from acting to focus on spending more time with his family.
But don't get too sad — he limited it to six months, saying he planned to take his son to Jack's Beach, an island he and Faris named after their son on the San Juan Island.
And I'm sure there will be plenty of adorable Instagrams.
