Ben Affleck has joked "it's hard" not to make his children into "props" for sports teams.

The Hollywood star and his wife Jennifer Garner have Violet, six, Seraphina, three, and seven-month-old Samuel together.

Ben is a big fan of the baseball team Boston Red Sox and has joked he has considered dressing Samuel in their kit.

"It's nice, I got a team mate. It's pretty exciting, it's a cool thing," he said of having a son. "I try to resist the temptation to make my kids props for sports teams [by putting them in] jerseys but it's hard."

Ben can't believe how his life has turned out. He loves being a father and a husband, although he used to wonder if family life was in his future.

"I have got to a place where it's hard to even imagine that I'd be able to get to," he told Access Hollywood. "Ten years ago I certainly wouldn't have imagined that I'd be married and have children and be working on [the] kind of material that was really deep and rich."

Ben loves hearing that people have enjoyed his movies. However, he doesn't listen to feedback too much.

"I think you can't put too much stock in people saying nice things or you have to put too much stock I the flip side," he laughed.
