— -- Chris Pratt is donating his time to a cause close to his heart.

The "Guardians of the Galaxy" star made a visit to Seattle Children's recently, spending a few moments with premature twins.

Pratt's own son, Jack, was born prematurely in 2012.

"Ever since Jack's premature birth, we have a special affinity for the NICU (neo-natal intensive care unit)," he captioned one photo. "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."

Pratt, 37, has been known to visit hospitals in the past, often spending time with children. On his Instagram page, the actor, who grew up in Washington, encouraged others to give back.

"Thank you @seattlechildrens for the opportunity to come by and brighten some days. My heart is full," he wrote. "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."
