Thanks for the reviews/follows/favorites This story was meant to be a one-shot, but it seemed most of you wanted another chapter, so here you go. Enjoy...

Brennan stood at the foot of the attic ladder, her arms outstretched in anticipation for the box Booth would eventually hand down to her, the box that had all the ornaments, lights, and tinsel for the Christmas tree, the box Booth was currently trying to find.

"Are you sure it's not in the other attic?" Booth called down to her. "I can't find it."

She crossed her arms over her chest and tipped her head up to the opening. "Maybe if you labeled the box like I suggested, we wouldn't be in this predicament."

"Oh, wait, I think I found it."

She could hear one of the plastic lids being pried off and then his pleased 'aha' that soon followed.

"You ready, Bones?"

She nodded. "Yes." She carefully grabbed hold of the box, sliding it down a couple steps and then grabbing both handles, carrying it into the living room where she had put the other boxes.

"Is there any more?"

"I don't know. Perhaps if the boxes were labeled, I would know if we were missing anything," she tossed back, exhaling as she set the box down. Her arms were tired and she was out of breath after moving the seven or so boxes of decorations.

"Well, I'm coming down. Let's just start on this stuff."

She nodded. "Okay. I'll go get Christine."

"I'm here, Mommy!" Christine announced, bouncing into the room. She had exchanged her dress and leggings for pink fleece footie pajamas with ice-skating penguins in Santa hats printed all over them and her hair was no longer clipped back but in pigtails, wet from her bath.

Booth walked in and over to the bar, grabbing the remote for the stereo system. He switched it on and Christmas music began to softly play in the background. He walked over to 'his girls' and lifted Christine up into air, spinning her around. "You ready to decorate this bad boy?" he asked her, glancing over at the tree that they had set up as soon as they returned home earlier.

Christine squealed, wrapping her arms around his neck. "Uh-huh."

He danced with the little girl for a little bit before setting her back down. "Well, let's get started." He walked over to Brennan, who was already starting to detangle the strings of lights. He stood beside her and leaned over, pressing a kiss to her cheek. "Need some help, there, Bones?"

Brennan tilted her head and gave him a little smile. She handed him another set and he and Christine got to work on that one. "I want to apologize for earlier."

He paused, raising an eyebrow at her. "Hmmm?"

"For my behavior at the tree farm. I wasn't in the best mood and I'm sorry if I ruined the experience for you and Christine."

"It's okay, Bones. We still had a great time. Right, Princess?"

Christine looked at him. "What, Daddy?"

"You had fun today, right? Helping me pick out the tree?"

Christine nodded. "Yeah."

"See? You didn't ruin anything," he told Brennan.

Brennan sighed. "Still, I'm sorry for my attitude."

"You're forgiven. You feeling better now?"

Brennan nodded. "Yes."

"Good." They dropped the subject and focused on the task at hand, while simultaneously listening to Christine sing along to 'Jingle Bells' before they both joined in at the chorus. It wasn't long before all the lights were detangled and Booth plugged them in one at a time to make sure none of the bulbs were burned out. Once they determined that all the lights worked, he climbed up onto the stepladder and motioned for Brennan to hand him the end of one of the strings. He weaved the lights through the branches from the top to about the middle of the tree before Brennan and Christine took care of the bottom half.

Christine stepped back and looked up at the lit up tree, her eyes sparkling. "What now, Daddy?"

"Ornaments."

"Yay!" Christine jumped up and down.

The three of them worked together, first hanging the generic ones before moving onto the personal ones.

Christine unwrapped a ceramic disk with the impression of a small foot. "Daddy?"

He finished hanging his and Brennan's first Christmas as a couple ornament, which was a present from Angela. The artist had designed it and had it custom made by a friend of hers. It was a man and woman, the figures looking remarkably like him and Brennan. The man was dressed in only his boxers, black ones with tiny accurately depicted skeletons on them, and striped socks, while the woman was clothed in only a Jeffersonian issued blue lab. They were holding hands and smiling, the hook to hang the ornament from the tree was a single handcuff.

"Daddy?"

Shaking his head, he refocused on his daughter, remembering that she had called him. "Yeah, Princess?"

"This has my name on it." Christine held up the disk by its red satin ribbon.

"That's because it's yours. That's your footprint."

Christine's eyes widened. "Daddy, you're silly. It's too small! See?" She leaned back and showed him her foot.

He tickled it and smiled. "That's how little your foot was when you were a baby."

"No way!"

"Yes way!" He paused. "C'mon, I know the perfect spot for that one." He walked with her to the tree and lifted her up so she could place it on one of the branches.

When the container was empty save for tissue paper and empty packages, Booth, Brennan, and Christine stood back away from the tree and looked at it. Every empty space was filled in with an ornament except for one.

Christine pointed it out. "We gotta put something there." She pulled the tissue paper out and pushed the packages aside, searching for an ornament to put there. She sighed and looked at her father. "Uh-oh."

Booth turned away from the tree and stared at his daughter. "What's wrong?"

"There's no more ornaments, Daddy."

"That's okay, Princess. We don't have to fill the tree completely."

"But that spot is nakey, Daddy. We have to put something there," Christine argued.

"Let's put the tinsel on and the star and then maybe tomorrow, you and I can go to the mall and look for another ornament for there. Maybe a piece of apple pie or a donut?" He smiled at her when her eyes lit up.

Christine tugged on Brennan's arm and pointed to another spot. "Mommy, I like that one."

Brennan followed her daughter's finger and smiled at the dolphin ornament. "I do too, Sweetheart." She paused. "And a trip to the mall won't be necessary."

"But Mommy—."

Brennan nodded. "I know, the naked spot, but I think I have the perfect ornament for there. I'll be right back." She disappeared, heading down the hallway to the master bedroom. She returned a couple minutes later with a giftwrapped box in her hands.

Christine took the proffered gift and was about to shake it until Brennan stopped her.

"Careful."

Booth looked at Brennan and furrowed his brow. "Bones?"

Brennan smiled at him, not giving away anything about the contents in the box their daughter was now holding. "You two should open it together."

Now he was even more confused. What could possibly be in the box? It was an ornament for sure, Brennan had said as much, but aside from that, he was clueless. He sat down beside Christine, who was sitting in front of the tree.

Christine scooted back until she was between his legs and started clawing at the silver and gold paper. When the last bit of wrapping paper was gone, she stared at the plain white box.

Booth pulled her fully onto his lap and scraped away the tape holding the lid of the box in place. He opened it and reached in, pulling out the clear glass frame that was hidden inside, his eyes widening when he saw what it was.

Christine tilted her head up at him and pointed to the black and white grainy picture. "What's this, Daddy?"

Unlike Christine, Booth knew exactly what it was and what it meant. He looked up at Brennan and blinked. "Bones?"

Brennan smiled, nodding.

Booth broke out into a huge grin and he laughed. "Really?"

Brennan nodded again. "Yes."

"Daddy!"

Booth glanced down at Christine. "It's called a sonogram, Christine."

"What's that?"

"It's a picture of a baby when it's still in the mommy's belly."

"Is it me?"

Booth shook his head. "No."

Christine pouted. "You make no sense, Daddy."

He laughed. "This is your little brother or sister's first Christmas ornament."

Christine crossed her arms over her chest and shook her head. "Daddy, you're silly. I don't have a little brother or sister. 'Member? There was no babies at the tree farm."

"You don't have a brother or sister yet, but you will soon. He or she is still in mommy's belly."

"How'd it get in there?"

Booth swallowed. "Uh, um, well—Mom?"

Brennan leaned back on her heels and shook her head. "This one's all yours, Dad." She laughed as she went into the kitchen to make some hot chocolate.

"Not funny, Bones!" He wracked his brain for some way to explain sex and reproduction to his little girl, but it ended being unnecessary, as Christine had already forgotten her question and was now chattering on and on about being a big sister and attempting to hang up the tinsel by herself. He exhaled. "Whoa, Princess." He stood up and carefully hung the glass globe ornament in the empty spot before assisting Christine, pulling long silvery strands out of her hair.

Brennan walked in just as they were finishing up. She smiled, seeing Christine sitting on Booth's shoulders, her arms stretched out so she could reach the top of the tree to place the star. "I have hot chocolate," she said when Booth stepped back to admire the finished tree. She gave a mug to Christine and then handed the other to Booth.

"What? You're not having any?"

Brennan swallowed hard. "No." The truth was she had taken a sip of Booth's in the kitchen and while it initially tasted delicious, it left her feeling a bit nauseated. She knew if she drank an entire glass, she would surely not be able to keep it down. "I'm fine."

He got what she wasn't saying and let it end there. He walked over to the couch, where Christine was already sitting down enjoying her hot drink. He sank down into the cushions and motioned for Brennan to join them.

Brennan sat on his other side and leaned into him, her head on his shoulder.

He hooked his arm around her back "We're gonna have another baby," he whispered, feeling extra giddy.

Brennan smiled. "Yes."

"You're sure?"

Brennan lifted her head and looked at him. "How can you ask that? You just saw the sonogram."

"Wait? That was—." He looked over at the tree and focused on the frame he had hung beside Christine's first Christmas ornament. Of course it was; he was just too shocked to make the connection before.

She laughed. "I'm ten weeks along. I was going to wait until Christmas to tell you, but when Christine brought up her desire to have a little brother or sister earlier, I thought tonight would be the right time. It is still relatively early in my pregnancy, so telling her so soon could be devastating if I were to," she swallowed, "miscarry, but I wanted to surprise you and I'm already showing. Barely, but in two weeks, I'm sure my pregnancy will be more noticeable, perhaps not to most people, but certainly to you, since you see me naked on a regular, if not daily, basis."

He leaned down and pressed his lips against hers, effectively shutting her up. He dropped his arm from around her back and rested his hand against her stomach, smiling wider into the kiss at the feel of the tiny bump under his palm. "How long have you known?"

Brennan sighed and scooted closer to him. "Almost two weeks."

His eyes widened. "Two weeks!"

"Are you angry?"

He shook his head. "No, but from this point forward, I want to be a part of everything. I'm in this 100 percent. No more going to doctor's appointments without me, got it?"

"They're usually very boring, Booth." She sighed. "Fine. I had no intention of keeping you out of this pregnancy."

He smiled. "Good." He leaned in and crashed his lips against hers once more. He pulled back a minute later when he heard the soft snores of his daughter beside him, swept up in Brennan and the pregnancy so much so that he had momentarily forgotten Christine was there. He kissed Brennan on the forehead and stood up, setting his mug on the coffee table. "I'm going to put her to bed and then I'll be back."

"I'll be here."

He scooped Christine up and carried her to her bedroom, where he tucked her in and kissed her goodnight, before he rejoined Brennan in the living room, practically skipping to the couch. "Now what do you say we celebrate properly?"

"What did you have in mind?" she asked, an eyebrow raised, one side of her mouth curved into a smirk.

"Beer hat?"

She rolled her eyes and pushed at his shoulder. "Booth!"

He laughed. "I'm kidding."

Her look to him told him she didn't believe him.

"Okay, I wasn't kidding, but how about a bath? Without the beer hat," he added.

She leaned against him and closed her eyes.

He suddenly realized how tired she must be. It had been a long day, after all, and she was pregnant. He smiled to himself, still not over the fact that they were going to have another baby. "On second thought, maybe we should postpone this celebration until tomorrow. I don't want you to fall asleep on me and drown."

"I'm not tired." She yawned, giving her away.

He laughed. "Yeah, sure. C'mon." He stood up, bringing his and Christine's mugs into the kitchen and putting them in the sink. He walked back to the living room where he found Brennan already asleep. He shook his head, unplugged the tree, and lifted her into his arms.

Brennan stirred, made a halfhearted protest, and then drifted back to sleep.

He carried her to the bedroom and laid her on the bed before going back out to make sure the doors and windows were locked and all the lights were off. He went into the bedroom again, brushed his teeth, and crawled into bed beside Brennan. He rolled over to face her and pulled her closer, wrapping his arms around her as she curled up against him in her sleep. "Goodnight, Bones," he said, even though he knew she wouldn't respond, and kissed her on the forehead. The last thought he had before falling asleep was that the only thing that would make this Christmas the best one he had had in years would be if he could convince Rebecca to let Parker visit…

He would soon find out that a pregnancy wasn't the only thing Brennan had been keeping secret.

As I said, this was originally going to be a one-shot, but I can keep going if you guys want more. Let me know.

Thanks again!
