Chris Hemsworth naps with his children in his arms in sweet Instagram pic

Sure, he often plays muscle-bound tough guys on the big screen, but in real life, Chris Hemsworth is a big softie — at least where his kids are concerned.

In fact, in a photo wife Elsa Pataky shared Instagram, the father of three can be seen playing the part of a soft surface to sleep on during a flight.

"Nothing better than sleeping in papa's arms!" Pataky wrote in the caption.

Nothing more swoon-worthy, either!

There's just something so sweet about seeing the star sacked out with 4-year-old daughter India snuggled up in one arm and one of his 2-year-old twin sons wrapped up warmly in the other — even the bag of chips smashed in the middle of them adds a cute (and oh-so-relatable) touch.

Of course, Hemsworth has been making us swoon with his dedication to daddy duties for a while now.

Just last month, he saved the day when a bakery couldn't prepare a cake in time for India's birthday by whipping up an adorable dinosaur confection himself.
