Ryan Reynolds has had a pretty good time being a dad to his baby girl James so far, but there is an aspect about it that scares him a bit. That may not seem like much of a shocker, but what he shared is probably not what you’re expecting. It’s not the sleepless nights or having to play bad cop sometimes or wondering if you’re doing it right—it’s time. The actor tells AOL Build in an interview Monday, “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?”
