I honestly don't know what this morphed into, well enjoy anyway! Please leave a review even though this is just a oneshot, they are extremely helpful and lovely!

What the bloody hell had he been thinking? Sure Dave was a great mate and as far as father-in-laws go he had hit the jackpot, but spending an evening babysitting Neal alongside his own newborn with nobody else to keep him company? Well this would be dreadful.

He liked spending time with Dave, really he did, but he had never been left alone with little Liam before and he most definitely didn't want his father in law to be the first to witness this endeavor.

But Emma had looked so exhausted, and her mother had been quick to suggest a girl's night away from their children, most likely because she herself needed a break too. True Emma had been reluctant to leave their child, with all of the spontaneous and constant crises around here it was understandable. Nevertheless she did need a break, and if she could trust anyone with her perfect, round faced little son it was said son's father, even if the father himself didn't quite have the same faith in his abilities.

So once he had agreed to take care of Liam while his Swan just relaxed for a night he could hardly say no to David's offer to babysit with him, especially when he had looked so excited to do so. Which is why, through all of these events combined, he ended up here, sitting on his and Emma's couch with a newborn clutched against his chest next to Emma's highly amused father.

He heard a chuckle rumble from beside him and he gently turned his head, so as not to entice any noise out of his son, and sent a glare in the direction of the laugh. "Is something funny mate?" He asked, eyebrow quirked, challenging him to say anything besides 'no'.

David put his hands up in surrender as the grin overtook his face. "It's just that I never thought I would see this. You clutching your son with your hook slightly angled towards the door in case you need to use it to defend the little bundle in your arms while simultaneously looking at your son as if he's everything." The blonde haired man snuck a glance at Killian's surprised but not disagreeing expression. "And in your case he just might be."

Well he couldn't argue that one, although Liam didn't make up his entire world. There was Henry who had become a son to him in all of the ways that matter, and of course his true love who had provided him with both of his sons and the happy ending he didn't believe to be in the cards for him at any point in his life. Of course, even if at times he may be loathe to admit it, the Charmings themselves had become very important parts of his life as well.

He wouldn't tell Dave that though for fear of endless mocking and holding it over his head. But yes even the prince had become an integral part of his life.

Killian nodded at his father in law with a slight smile adorning his face, allowing his own chuckle to escape as he glanced back down at his son, whose face was still tinged slightly red from his entrance into the world just two weeks prior. "Aye, he certainly is a large part of my world." At Killian's few words and the slight vibration it produced the baby in his arms began to squirm slightly, letting a slight cry out.

David smirked at Killian's panicked expression as he became completely still. "You alright there, mate?"

Killian nodded with a large swallow, being careful not to move any other part of his body. "Of course, I just-maybe we should stop talking as to not disturb the lad."

The blonde man shook his head, entirely amused at the sight in front of him. "Hook if the baby is gonna cry then he's gonna cry it's just a matter of when." Just as the words left his mouth Neal came charging through the living room, somehow being loud without saying any words at all.

Neal was growing up fast and looking more and more like his sister everyday which of course only made Killian that much more fond of him. Neal had taken an affinity to Killian as well, Killian's own troublemaking tendencies making Killian that much more appealing to him.

Killian of course embraced this and used the lads own troublemaking to his advantage and played countless pranks on Dave and even a couple on Emma, the latter of which never ended well.

Killian looked at the now three year old alarmingly, and if he hadn't been only three probably would have received a subsequent death glare.

As was feared Liam began to stir letting out cries that certainly weren't possible for somebody of his size.

Killian snapped towards David as Liam kept his cries steady. "Look what you've done mate!"

"Me? That was hardly my doing, if anything blame Neal." David said indicating the mischievous three year old who was currently looking at the pirate with a guilty smile as if he knew what he had done. He didn't look entirely sorry though, some amusement in his eyes that very much mirrored his sister.

David flashed a smile at Killian. "Come on Hook, how can you be mad at that?"

Killian sighed in resignation as he glanced down at his still whaling son. "I suppose I can't, especially when I've seen that very look on an older, female version of him." Killian eyed the toddler closer and was amazed at just how similar Neal looked to his sister. "Gods it's amazing how much he looks like Emma."

David smiled wistfully and nodded. "I know I see it everyday, sometimes I can't help but just wonder." David said trailing off at the end of his statement with a small shake of his head as if to rid himself of the intruding thoughts.

Killian shot him an inquisitive eyebrow as he continued to gently rock Liam to calm him down. "Wonder what mate?" The dark haired man asked gently.

"I just-I just can't help but wonder if this was how Emma was as a child." David said with a sigh, glancing over briefly to catch Killian's sympathetic yet understanding look as Liam's cries began to subside. "You know? Like did she cry a lot, or was she a shy quiet child? What was her favorite thing to do? What calmed her down?" David said listing off the various questions that swarmed his mind his voice shaking more and more by the end.

Killian looked down at the tiny bundle in his arms, somehow even more grateful than he already had been. Feeling the emotional tension filling the world Killian plastered his signature smirk onto his face. "Well mate judging by Neil's rambunctiousness and amount tears as a child along with Liam's inclination towards crying as a first response I'd say that it's a safe assumption she was similar." David shot him a grateful smile urging him to continue. "As for the rest-well it isn't too late to find out. Bloody hell I could tell you the answers to most of those questions."

David cleared his throat, emotion still coating his voice. "Could you maybe, tell me? I mean if any of them are like things that a father shouldn't know then don't tell me but-."

The former pirate shot him a wicked grin. "But mate then I'm not sure I can really answer your questions."

David began to stand up, his face twisted up in disgust. "Never mind forget I asked."

Killian chuckled. "Come on Dave I was just kidding."

David shot a glare in his direction. "Not buying it."

The other man let out a long sigh. "Her favorite thing to do, from my experience anyway, is spend a night curled up on the sofa watching one of those Netflix thing with her family. As for what calms her down? Well just reassurances that she's no longer alone, and that for many people she's one of the most important people in the world."

David shot him a small smile. "Thank you Hook."

"No problem mate, although something tells me that you already knew all that. You may not have had all of those beginning years with her but you have her now, and even at her age she still needs her father." Killian gave him a wry side glance. "No matter how painfully annoying and optimistic he may be."

David clapped him on the shoulder with a smirk. "I'm gonna ignore that last part because something tells me you have a long night ahead of you." He said glancing at the again squirming baby in Killian's arms.

"I'd wager that you're not wrong."

The prince smiled lovingly at the sight of father and son. "You're a good father Hook. I know you were nervous about looking after him without Emma tonight but you're doing a great job."

Killian smiled sheepishly, not meeting David's gaze. "Well I try."

"If I didn't think you could do it then I would've said something by now, trust me Hook. I mean that is my handsome prince of a grandson."

Killian shot his gaze up to David's. "Prince? I don't think so mate, my lad is a pirate through and through."

"Actually Hook he is royalty, on account of your wife being royalty. Which now that I think about it, makes you royal by marriage, Prince Hook." David said teasingly as Killian squeezed his eyes shut.

"Bloody hell, lad don't listen to him, he was cursed for 28 years he doesn't know what he's saying."

Yeah he knew that babysitting with Dave would end badly.

Nobody ever could have guessed so though by the time Emma and Snow arrived home. The mother daughter duo were greeted to the sight of the two men asleep on the couch, Liam protectively against Killian's chest and Neal curled up against David.

"Should we just leave them?" Snow asked in a hush voice.

Emma nodded with a small smile as she placed a light kiss on Killian and Liam's foreheads. "They look pretty comfortable, I think it would be a crime to ruin it."

A/N: I don't even know what this was…this started completely different and just kinda morphed into this. Hope you enjoyed the Captain Charmingness regardless. Reviews are love!
