While this isn't the first time Pratt has shared a throwback snap, the little boy usually featured on his Instagram is Jack, his 3-year-old son with wife Anna Faris.

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.

dad /dad/ noun informal One's father Verb "Chris made a Donald Duck pancake that was basically a perfect photo copy of the picture he saw online and his son Jack refused to see the resemblance, probably out of spite or a deep seeded jealousy of his father's pancake skills, regardless Chris continued to dad.

This morning Jack found a rainbow on the wall. I honestly couldn't figure out where it was coming from which according to science means it's some sort of portal. You ever see Stargate? Exactly. We were careful not to get too close. I snapped this photo and it dawned on me how much Jack looks like Anna. They are both so beautiful. Sleeping in with the two of them is my greatest treasure.
