While some fathers-to-be are nervous with the prospect of caring for a small human being, "Croods" star, Ryan Reynolds is nothing but excited about his incoming first baby with wife Blake Lively. The actor shares that he already knows how to change diapers or deal with diarrhea.

In an interview with People magazine, Ryan Reynolds shares how uniquely different he is from other fathers-to-be. He is not intimidated with what would happen with the newborn under his care when the time comes because he does not have a weak stomach. He told People magazine that he's well verse when it comes to caring for babies. "I'm good with diapers, diarrhea and all that kind of stuff because I have lots of nieces and nephews, so I've done it all before," he explained.

He said that he's hardly paralyzed by fatherhood fears. He said that most new dads are often nervous because they keep thinking and dwelling on the mistakes they do not want to commit when caring for their babies. However, unlike them, Ryan said he's open to making mistakes because he knows it would be a learning process. "I'm at that stage still where I'm focused primarily on being open and understanding and leaving a lot of room for error," he detailed.

It was only in October when Blake Lively, 27, announced that she's carrying baby via her own lifestyle site, "Preserve." Ryan said that they still do not know the gender of the baby, but their excitement would not go away. Back in October, they even said they already have some baby names to choose from already and warned people not to expect names that would be "Hollywood-y."

If Ryan is set to be a father, Blake Lively is also. Her friend and co-star in "Sisterhood of Traveling Pants," Amber Tamblyn shared that Blake would be a great mother, joking that she herself would love a baby with Blake Lively and be next in line to Ryan to get to Blake's "uterus." Joking aside, she personally thinks Blake would turn out to be the dad, while Ryan would be the mom.
