The Jurassic World star recently stopped by the Seattle Children's Hospital to hang out with young fans, and his photos and sweet messages are giving us all the feels. "Ever since Jack's premature birth, we have a special affinity for the NICU (neonatal intensive care unit)," the dad of one began one heartfelt post, referencing the health issues that his own 4-year-old son, Jack, has had. In the photo, the 37-year-old smiles at the camera as he holds two premature babies. He continued, "Today I spent a little time with Coen and Zion, twins who were born too early only a pound and a half each. Thank you to the doctors and nurses at @seattlechildrens The boys are doing fine. Although they're both missing their big sis." The actor then posted a cheeky photo of him and a cancer patient named Madisen hilariously showing off their 'guns by flexing their arms. "Madisen is #strongagainstcancer. What an awesome kid with such a beautiful smile. She's a lover of art and fashion and she's going places," he wrote alongside the inspiring photo. "Thank you @seattlechildrens for the opportunity to come by and brighten some days. My heart is full. Proverbs 3:27 Don't withhold good from those to whom it is due, when it is in the power of your hand to do it." Lastly, Pratt shared a shot of himself sitting alongside a cancer patient named Rowan. He wrote in the caption: "Rowan was Groot for Halloween and his brother was Rocket. What an awesome kid. Great parents and from a great family. You're in my prayers tonight little man. Stay #strong @seattlechildrens." Chris Pratt Misses "Fat Pratt" - and Says Wife Anna Faris Does Too! As if we needed another reason to love Chris Pratt!
