Eddie Redmayne on Newborn Daughter’s Trip to Rio: I Feared She’d Cause England’s ‘Lack of Success’ at the Olympics

Eddie Redmayne may be starring in the upcoming Harry Potter spin-off Fantastic Beasts and Where to Find Them, but the actor’s No. 1 role is dad to 4-month-old daughter Iris Mary.

And just like most new parents, the Oscar winner isn’t getting much sleep.

“Before you’re a parent, you hear people talking about , then suddenly you’re the guy who’s floating in a constant jet lagged , with an IV of caffeine,” Redmayne, 34, joked on The Ellen DeGeneres Show Tuesday.

Of course, the new dad has no regrets — even in the middle of night.

“It’s that amazing thing when it’s 3 o’clock in the morning and you go in and you’re gently furious, and you get a little smile and your heart breaks a bit, and it’s totally worth it.”

Ellen DeGeneres then brings up the fact that Redmayne’s wife Hannah tends to run late for things — for example, she was late to the twosome’s 2014 wedding — and asks if Iris had a similar delay in her birth.

“The baby was late! In fact, Hannah was totally on time, but the baby was late,” the British actor admits, sharing that his daughter arrived about two weeks after her due date.

He adds jokingly, “Iris appeared in the world and I gave her a stern talking-to.”

“Was she a large baby?” DeGeneres asks.

Redmayne confirms she was large, at 8 lbs.

“That’s not big … I was 11 lbs., 12 oz,” the host says, joking, “I didn’t walk until I was like 2. I was huge.”

Baby Iris has already proven herself a seasoned traveler, according to her dad. In fact, she got quite the introduction to flying when the family of three jetted to Brazil for the 2016 Summer Olympics — when Iris was only 8 weeks old.

“I’ve always had this utter fear of flying with children, and this was the first time she was flying, and of course we were on a flight with basically most of the British Olympic team,” he says. “And there was this fear like, ‘What if she cries lots and then they don’t sleep and they blame all of their lack of success on Iris?’ ”

“But she was amazing,” he continues. “She was so calm. I was holding her for a bit while she was being really calm and she cried and I gently handed her to Hannah, but then she was amazing for the whole flight.”
