Raising a child and sharing that special sort of unconditional love is an experience like no other.

But that's not to say that it's plain sailing.

Anyone who’s raised a child will confirm that they don’t call it the hardest job in the world for nothing.

And there's another factor which makes the job exponentially harder.

Being a single parent is always tricky.

After a friend tagged him in the post, Casey put himself forward. "I was like, what the heck, I’ll do it. I had never met Jenn before until the day of the shoot," Casey told Business Insider.

But there's nothing he wouldn't do for his daughter.

Casey explained he was quite nervous when Jenn asked him to wear the tutu...

"I’ve never worn a tutu or done anything like that before – I was definitely willing to do it for Lyla, though."

Jenn wanted to capture the natural loving relationship between the pair.

"I simply wanted to do something that allowed them to interact and show the natural, loving relationship the two of them share," she said. “Lyla was so sweet and just loved on her daddy, ran around, and laughed."

It didn't take Casey long to embrace his new outfit...

"I just put on a tutu and started interacting with Lyla and kind of forgot I was wearing it at all," he said.

Lyla means to world to Casey.

"She is my world, she was just having a blast like normal. I consider myself a ‘manly’ man, but with her I lose all that and just be her dad."

And he says this snap is his favorite from the shoot.

“My favorite one is of me holding her in the air and she’s grabbing my face," he said. “That’s kind of our thing – she loves my beard." We're not crying, you're crying.
