Ryan Reynolds has revealed a scary aspect to being a dad that he hadn’t realised until his daughter arrived.

The Green Lantern star and his wife Blake Lively welcomed their baby daughter James around six months ago and since then Ryan has given a few chats on how his life has changed.

He told AOL Build: “Yeah, you suddenly feel the inexorable amount of time go by. There’s nothing that ages you faster than having a kid, and that’s not because you wake up in the middle of the night every five seconds because someone’s got to shit themselves — it’s really because you’re looking at this person and time is just flying by – like, how is it possible that you’re already half a year old?

“And when most people are given at best 90 of these years on this planet, you start to look at it like that, it freaks you out a little bit. You start to make the most of the time you have with this person.”

But Ryan admitted he was in a better position than most when it came to being able to spend time with his child.

He said: “We have long hours but we also get breaks, and unlike most people who get one week off a year, I might have three months off which is so nice.

“Those three months used to drive me insane when I was a young buck, single and carefree, but now I just want to be with my daughter, so yeah. I’ll do anything to be with my wife and baby.”

Earlier in the year, he told E! of his experiences as a dad: “There have been times where I woke up, literally had no idea I had been walking for five minutes.

“But you love it. You wake up in the middle of the night, you got a big stupid smile on your face. I was telling someone else that. Anything else that woke you up every 45 minutes, you’d kill it. But when it’s a baby, it’s the best thing that ever happened to you.”
