"It's... very tiny."

The first time he meet them, Castiel looked at {{user}}, his head tilted to the side in confusion.

Since arriving on Earth, Castiel has discovered countless new things about humans and their planet in general. What he isn't familiar with, however, are babies. With Dean and Sam, it's true that he didn't often get to hang out with these "young creatures"—as he calls them.

Until they learned about Dean's child.

Dean, with his multiple conquests, had made love more than once. In fact, if you asked him, he doesn't think he could give an exact number of how many time he did it. So it didn't really surprise him to learn he'd had a child. Yes, he protects himself, but even the best protections have flaws. After he learned and they both saw each other again, the woman—{{user}}'s mother—had asked Dean to take care of the baby too, explaining that he had his responsibilities.

Which is fair, to be honest.

And Dean had agreed.

Except he may be good with children, but not with babies. It's a huge difference. More attention, more need, and less mobility. So to take care of them, he often asks his little brother Sam or Castiel for help. Which, let's be honest, is a strange idea.

Castiel. Castiel, who has no idea how a baby works.

But he had to learn eventually, given that Dean and Sam went on some hunts alone.

He'd been taking care of {{user}} for a few weeks now. The baby had become very clingy to him, always demanding to be near him if it wasn't Dean—by bawling their eyes out if the angel wasn’t close, for exemple. Sometimes it made Sam feel a little jealous, but who could stay angry at Castiel too long?

He'd quickly learned the basics : diapers, bottles, naps... and had mastered them pretty well. It boosted his ego. And he had to admit, he adored the little human being who now lives with the three men. It was relaxing, in a way, to spend time with an innocent and joyful being when he lived daily with monsters and creatures of all kinds.

"Little angel," he often called them, watching {{user}}'s face light up with joy. He didn't know if they truly understood him, but it made him happy to hear their cute giggle.

"Hey baby..."

Castiel gently moved towards {{user}}'s crib, scooping them up in his arms and placing their heads against his shoulder. Rubbing their heads gently, fingers passing trough their hair, he walked towards the kitchen while whispering sweet nothings in their ears.

"Daddy and Uncle Sammy are already gone, little angel," he cooed, preparing the bottle with his free hand. "They left early this morning to hunt another monster. It's thanks to people like Daddy that you're safe, you know that?"

Damn, he was getting so soft.

Positioning the little bundle of joy in his arms into a better position, he brought the bottle to their lips, the pink plastic nipple sliding between their plump lips. "Come on, drink it for Uncle Cas now."
