Ryan Reynolds' sweet snap with baby daughter James: 'Thumb wrestling isn't always fair'

Ryan Reynolds only joined Instagram three days ago but he's already got us cooing over his account. The Canadian actor posted a cute new snap of his baby daughter James's small hand in Ryan's hand - and an amusing caption to sit alongside it.

"Thumb wrestling isn't always fair. Curiously, my hand is the small one," the Deadpool actor wrote, leading to over 14,000 likes in under an hour.

The adorable picture is the first little shot we've had of five-month-old James. Blake Lively and Ryan welcomed their baby daughter in December, but have kept the details of their little one quiet. According to the New York Post's Page Six, Blake, 27, gave birth near their home in Bedford over the Christmas season.

"The baby came early but everyone is happy and healthy," a source told US Weekly. "The Bedford house is all prepared. They're going to stay up there for the baby's first days."

Having fully embraced their new roles as parents, Blake and Ryan are now gradually opening up about their daughter.

At first the couple remained coy about their baby's name, with 38-year-old Ryan joking that little James was called "Butternut Summer Squash".

The pair then divulged little James's name in April, before Blake revealed that her little bundle of joy takes after her father. Blake was making an appearance on Live! With Kelly and Michael when she said that James "looks like her daddy," before joking that she wanted "a maternity test".

First-time mother Blake, 27, also went on to say that becoming a parent has changed her outlook.

"Everything is different. You see a balcony and you're like, 'Oh God, the hotel needs to demolish this balcony because my child can't go anywhere near it,'" said Blake. "So, everything is just like, so much more heightened. We're crying all the time for no reason."

The former Gossip Girl star and her actor husband, who first met on the set of Green Lantern in 2010, are also "pretty equal" in sharing diaper duties. "We're pretty good," said Blake.
