Jimmy Fallon has had quite the year, what with becoming the new host of The Tonight Show AND welcoming a daughter in July. So how does the 39-year-old do it all?

"Of course when you have a baby, sleep is not an option," the host shares. "You can’t sleep. Even on vacation, you wake up at 6:30 a.m.”

But the SNL alum wouldn't dream of complaining, especially given his little girl Winnie was five years in the making. Jimmy and wife, Nancy Fallon, 47, struggled with infertility before eventually turning to surrogacy.

“You’re talking to people who tried for a long time and finally have our little family, so we’re just like, ‘Hey, man, if a little crying is all you got, it’s fine,’" Nancy says of their 11-month-old.

"Our patience level is so high because we are so joy-filled that she’s with us.”

Jimmy calls being a father "the most exciting, amazing thing that ever happened to me," adding, "my life has never been this cool."

“There’s no need to stress because it’s all great," the star explains. "The volume gets turned up on life."

Nancy describes how her husband's enthusiasm is unparalleled. "It’s seriously Christmas morning every day for Jimmy," the film producer tells People magazine. "He can’t wait to see this crazy thing who has grown slightly more overnight.”

Looking at both his personal and professional lives, Jimmy can't believe his luck. "I never knew I could be this happy, and that’s the truth.”
