The Game of Thrones star became a dad five months ago.
Kit Harington revealed he didn't realise there's no break from parenting until he actually became a parent.
Whilst promoting the upcoming season of
Modern Love, the actor opened up about new parenthood following the birth of his first child with wife Rose Leslie five months ago.
When asked by
Access Hollywood what surprised him most about fatherhood, he said: "They tell you and they don't tell you. Everyone goes, 'Look, it's big what you're about to go through,' and you have no way of knowing that until it happens.
"What surprises you is: You go, 'Oh, this goes on forever.' Like, you don't get a break from it. Every day, I wake up and I look after this little human and now we're part of a unit together."
Kit added that the couple, who met on set of the HBO show and later married in 2018, were drawn closer by the birth of their son.
"I think the thing that surprises me most about fatherhood is you are now a unit, the three of you," he continued.
"And that's a whole new dynamic you need to find, and pretty much find every day: as he grows and changes, how does that change you? It's a beautiful thing, it really is."
Rose, who starred in the first three seasons of the Good Fight, confirmed the pair were expecting back in September when she and her bump graced the pages of Make magazine.
