With this one I kinda just let go and started writing, there was no real plan to it.

Imagine The Company Baby Sitting

"So why exactly are you taking care of this child if it's not yours?" Kili asked looking at the baby that was sitting in Linda's lap staring at him with its hand in its mouth.

"I'm babysitting." Linda said. Bilbo looked alarmed.

"Baby-whating?" He asked with wide eyes.

"I'm watching someone's kid so they can do something else for a few hours. I don't actually sit on the kid." She said with a chuckle.

"But why?" Ori asked tilting his head.

"Cause I like kids and I get paid." Linda said bouncing the baby on her knee making him giggle.

"Why don't you just have your own kids?" Fili asked with a confused frown.

"Let's see … cause I'm only 23 and I wouldn't get paid for it." She said. "I only do this on the weekends anyway I wouldn't have time for a kid of my own."

"I don't like it." Kili said with a frown. "It won't stop staring at me."

"He's not an it, Kili, his name is Joshua." Linda said leaning down to smile at the baby. He smiled back his hand still in his mouth.

"It's drooling." Ori said.

"Babies drool, Ori." Linda said as she wiped the baby's mouth with a small cloth.

"Um, Miss Linda?" Bofur asked as he walked into the kitchen.

"Yes?"

"There's a strange sound coming from your bag, upstairs, thought you ought to know."

"Oh that's my phone." Linda said getting up. "Here, Kili, will you take him for a minute?"

"What? Me? Why? Give it to Fili."

"I don't want it." Fili said crossing his arms.

"Kili." Linda said with pleading eyes.

"Alright, alright, give it here." He said holding out his arms.

"Thank you, I'll be right back." Linda handed him Joshua. She turned to run from the room then stopped.

"Bofur, why exactly were you in my room in the first place?" She asked remembering her bag was in her room and the door had been closed.

"Trying to stop Nori from snooping." He said. Linda groaned.

"Nori!" She shouted before sprinting upstairs. Kili held the baby at arm's length. Bofur snickered at him before leaving the room.

"He won't bite you." Bilbo said shaking his head.

"How do you know?" Kili asked leaning his head away.

"He hasn't got many teeth yet." Bilbo said. "And don't hold him like that." He added with a frown.

"If you know so much why don't you take him then?" Kili said and started to give him to Bilbo.

"He's half my size!" Bilbo said holding up his hands with wide eyes, taking a step back.

"Give him here." Thorin said coming into the room. Kili gladly handed the baby to his uncle who cradled Joshua in his arm. Linda ran back into the room.

"Okay, guys, don't hate me but Toby got hurt playing basket ball at the gym so I have to go pick him up then bring him to the doctors and I can't bring the baby with me because I don't own a car seat."

"I'm gunna be honest, I didn't understand that." Kili said with a frown. Linda sighed.

"Can you guys watch the baby for an hour while I go pick up Toby?"

"An hour?!" Fili exclaimed, his eyebrows shooting up.

"Please, I need to go get Toby. Joshua's mother won't be back to pick him up until four and it's only twelve."

"We can't take care of a baby!" Kili said. Linda looked distressed.

"Go." Thorin said. "I had to take care of them when they were small," He said nodding at Fili and Kili. "this will be no trouble."

"Thank you so much. It shouldn't be too hard I've already fed him so if you just put him down for a nap you'll be fine. I'll be back as quick as I can." Linda said grabbed her coat and her keys.

"Hurry back!" Kili shouted after her as she left.

"Ridiculous." Fili said. "Taking care of someone else child. His mother should be the one taking care of him not Linda and certainly not us."

"I'm sure the mother has her reasons." Bilbo said. Kili suddenly let out a surprise yelp.

"It's got me!" He shouted in surprise. Joshua had reached out and grabbed some of Kili's hair. "Get it off get it off!" Thorin laughed causing the baby to gurgle and giggle happily.

"I think he likes you." Thorin said.

"Yeah well make it stop." Kili said pulling his hair out the baby's small grip. The baby stared at him with wide eyes. "Oh no. I think I broke it." Then the baby started wailing loudly. Kili, Fili, Bilbo and Ori all covered their ears. Thorin frowned and started rocking the baby back and forth.

"Now look what you did!" Fili yelled at his brother.

"How is this my fault?" Kili asked with wide eyes. Ori suddenly grabbed a small bear from the couch that was next to a baby bag and held it in front of the baby.

"Don't cry." He said. The baby slowly stopped crying and stared at the bear. "Look at the happy bear." He moved the bear from side to side. The baby started smiling. "That's right, smile, don't be sad." The baby reached out for the bear. Ori gladly let him take it.

"It's actually kinda cute when it's quiet." Kili said.

"He only started crying because you pulled back your hair."

"It's my hair. Not my fault the little guy's as bald as Dwalin." Kili said crossing his arms. Thorin chuckled.

"What did you say about me?" Dwalin asked as he came into the room.

"Nothing." Kili said shaking his head with a smile. Dwalin raised an eyebrow at Thorin holding Joshua.

"Who's baby is this?"

"Linda's baby… baby…." Fili said trying to remember the term Linda had used. Dwalin's eyebrows shot up.

"The girl has a baby?" He asked.

"No no no." Bilbo said quickly. "She's watching someone else's baby for them. She called it baby-sitting, but there's no sitting on any babies involved." He said. Joshua stared up at Dwalin with wide eyes. Dwalin stared back.

"I think it likes you." Kili said. Dwalin gave Kili a look. "Or not."

"Where is the girl?" Dwalin asked.

"Picking up Toby, he got hurt by Jim while playing a game involving a basket and a ball so she's taking him to the doctors." Kili said.

"Who's Jim?" Dwalin asked. Kili shrugged. "Why not just bring him home and have Oin look at 'im?"

"They probably have much better doctors to look at him." Bilbo said. "No offence to him of course." Bilbo added looking to the doorway to see it Oin had heard him.

"He's upstairs." Dwalin said. Bilbo nodded.

"So what do we do for an hour?" Fili asked.

"You wanna play Mario Cars?" Kili suggested.

"Kart." Fili said. "Mario Kart."

"Mario Kart." Kili said rolling his eyes.

"We can't, Toby never showed us how to set it up." Fili said.

"Why don't you two watch the baby?" Thorin suggested.

"I thought you were going to." Kili said with wide eyes.

"You wanted something to do." Thorin said as he started to hand Joshua over to Fili.

"No no no no no." Fili pleaded but had to take the baby. He held him at arm's length like Kili had.

"This will be good practice for you." Thorin said. Fili's eyebrows came together in confusion.

"Practice?"

"You're going to have an heir someday." Fili's eyes widened and Kili started snickering. "I don't know what you're laughing at, you might have one too." Thorin said to him. Kili's eyes went wider than Fili's. Dwalin burst out laughing and Ori chuckled behind his hand.

"We'll leave you three alone." Dwalin said putting a hand on Ori's back to lead him from the room.

"Come along, Bilbo." Thorin said as he started to leave. The two brothers looked at Bilbo with pleading eyes but Thorin had started leading him out. Bilbo gave the two a sympathetic look as he left. The brothers looked at one another in utter panic.

"You take 'im." Fili said holding him out.

"Why me? You need the heir more than I do. You'll need the practice more." Kili said pushing the baby back (pushing against Fili's hands of course not the actual baby).

"You can be king, here." Fili said pushing it back.

"I don't want it." Joshua began giggling as he enjoyed the ride between the two brothers.

"Take it."

"No way."

"As your older brother I'm telling you to take this baby."

"I don't want the baby."

"Oh for goodness' sake." Bilbo said coming back into the room. The two brothers watched him go over to the couch and pull out a baby blanket from the baby bag before putting it on the floor. "Put the baby on this." Fili quickly went over and put the baby down on his back. The baby rolled over and looked up at him. "Now just sit here and watch him." Kili grinned and held up a finger.

"Baby-sitting; I get it." Bilbo sighed and left the room.

I thought that last part was pretty funny, I imagined Kili's face as he came to that realization.

If you guys want me to make a part two to this just ask and I'll make it, where Linda come back with Toby. Not sure what else to add but yeah.
