Booth went up the stairs after parting from Lizzie to find both girls sitting with Brennan and Drew on their bed, piles of children's books surrounding them.

"Girls, I don't think we're going to have time to read all of these books to him tonight. Why don't you pick out one each and you can read more to him in the morning? All three of you need to get to bed soon."

Booth sat in the hall, listening to his wife and sisters read to his son. He had never imagined he'd have such a big family, that his mother, of all people, would be back in his life and begging to stay.

"Goodnight, baby Drew," he heard Sasha croon. Sadie ran out of the room and down the stairs without seeing Booth. Sasha came skipping out soon after and tripped over her own feet. She landed hard but without sound. Booth stood and scooped her up, checking her over for any obvious injuries.

"You okay?"

"MmHmm," she mumbled. She leaned up and placed a small kiss on his forehead, "Drew is super cute. You know what?"

"What?"

"He needs a sister."

"You think so?"

"Yes."

It was such a simple conversation between siblings but there was something about Sasha's presence he loved. It wasn't that he hated his other sister, she didn't do anything to him, but it was the younger girl's demeanor and take on the entire family situation.

"Well, I think you better tell Bren that," Booth told her, knowing his wife would probably turn that idea down.

"I already did."

He raised his eyebrows at her. "Really?"

"Really."

"Okay, smarty pants, are you going to tell me what Bren said?"

"She said it was up to you."

"That is exactly what I said," Brennan whispered behind them, holding a sleeping Drew, "I would appreciate it if you two kept it down just a little bit so he doesn't wake up."

The two reunited siblings kissed the baby goodnight one last time before Brennan put him in his crib.

"You should probably go to bed yourself, missy. You look awfully sleepy," Booth whispered to his sister.

"I am. Do you have to go to work tomorrow?"

"Yes, but I'll hurry home. Okay, me and you are going to have a mission when I get back tomorrow."

"What's that?"

"We're going to try to teach Drew to walk?"

"Really?"

"Shh! Yeah, but you gotta go to bed, okay?"

"'Kay. G'night, Seeley. Love you."

"Love you, too, Sasha. Goodnight." He watched her scurry down the stairs before going into his own room to get ready for bed. He changed into pajama pants and went into the bathroom where Brennan was brushing her teeth. She moved over to make room for him in their small bathroom while he slid the comb through his short hair.

"Did you really say that to Sasha? That it was up to me?"

"I did."

"Is that the truth or were you just saying that to calm her down?"

She rinsed out her mouth and placed her toothbrush back in the cup. She then stared down Booth through the mirror for a few seconds as if thinking of a different answer.

"I am open to the idea. Although, Drew isn't even walking yet and to bring another infant into the house at this stage would cause chaos!"

"Why didn't you call me to tell me that Lizzie was here?" He wasn't mad. He knew in the back of his mind that she probably a rational, logical reason for not telling him and as it turned out, he was right.

"It was your first day of work. I was allowing you to adjust to your surroundings, meet new people and establish relationships with your superiors," she explained, "You didn't need any distractions. Are you upset?"

"No! Do you want more kids?"

"Yes."

"Now?"

"No."

"Good."

"Good."

They finished getting ready for bed in silence, dancing around each other like they did every other night. He crawled into bed after her. She sat up, red pen in hand with a thesis paper on her lap. There were red marks everywhere and Booth instantly felt bad for the student. He knew Brennan was probably a tough professor.

"Put it away, Bren. Come to bed," he whispered as he rested his head on her shoulder. She smiled and tossed the paper and pen on the bedside table. She dipped her head down and her lips met with his. She moved on top of him and he let her take control.

"Mmm, I love it when you do that," he mumbled.

A/N: I'm sorry my updates have been so few and far between (and that this one is SO short) but my muse for this story has been a bit dead. I've heard spoilers for the next season and I'm pretty sure that's what's been committing the muse killings. So in order to get back on track on this story, I'm going to write some stuff to get that out of my system. I'm very sorry for the lack of updates that will occur in the next few weeks.

On another note, please let me know what you think. I think after the angstiness of the last update, we were all due for some fluff :)
