Los Angeles - Ryan Reynolds is "good" at changing diapers.
The 38-year-old actor and wife Blake Lively, 27, are expecting their first child together and the Green Lantern hunk is looking forward to being a hands-on dad and isn't even concerned about the messier aspects of fatherhood.
He said: "I don't have a weak stomach. I'm good with diapers and diarrhoea and all that kind of stuff because I have lots of nieces and nephews, so I've done it all before."
Though the couple don't know whether they are expecting a boy or a girl, the Proposal star is looking forward to having a little "buddy" to hang out with.
He said: "I'm just excited about having a buddy. We don't know if it's a boy or a girl yet, but whatever it is, you have this tether to reality that never goes away."
Though Ryan is excited about being a dad, he knows he needs to leave "room for error" as he won't do everything perfectly because it is all new to him.
He told People: "For a lot of new dads, you tend to dwell on the mistakes you don't want to make.
"I'm at that stage still where I'm focused primarily on being open and understanding and leaving a lot of room for error."
