Ahead of Father's Day, Chris Pratt reveals what new baby Lyla has taught him

Chris Pratt and Katherine Schwarzenegger welcomed their first child together, daughter Lyla, last August. The Marvel movie star, who shares an 8-year-old son Jack with ex-wife Anna Faris, explained what having a second child taught him.

"The greatest gift that I've seen so far, the second child really shows you the uniqueness of the first child," Pratt told E! News' Daily Pop.

The "Jurassic World" star explained, "When you have one child, you just think, 'Oh that's what babies are like.' And then a second child comes along, and they might do things differently from the get-go, and you say, 'Oh wow. OK, so that was actually unique what my first child had done.''

"Each child is unique and special and they're not just punched out of a mold," he continued.

Pratt also has something else to celebrate this Father's Day: the upcoming premiere of his Amazon Prime sci-fi action film, "The Tomorrow War." In the movie, which debuts July 2, he plays a soldier thrown into a far-future alien invasion on Earth.

Pratt co-produced "The Tomorrow War," which also stars Yvonne Strahovski, J.K. Simmons, Betty Gilpin and more.
