Author's Note: Well all the angst was killing me so I wrote a fluffy mother's day drabble. But the angst will (hopefully) be over soon because WATERSHED IS TOMORROW.

Disclaimer: I have a month of Freshman year left. So no, I'm not Marlowe.

It's a beautiful picture. Sunlight streams through the curtains, painting her face with dim light. She lies on the bed, her dark hair streaming out like sunbeams. Ignorant to the world, she keeps her eyes planted solely on her stomach as she slowly caresses it.

Castle knocks on the doorway, grinning. "Hey baby, brought decaf."

"Who are you talking to?" she asks, reaching out for the cup. "Me or the fetus?"

He shrugs, letting his fingers linger on hers as she takes the coffee. "Both."

Feigning a glare, she stares him down. "Call me 'baby' again and I'll break both your legs," she threatens, biting her lip to keep back a smile.

He settles down next to her, sipping his coffee. "No you won't," he comments, eager to start banter because he's just so happy. They're pregnant.

She nods. "You're right, I wouldn't. But you know what I would do?" Beckett responds, bringing a hand back to her stomach.

"What?" the writer asks on a laugh, resting his hand over hers.

"Take away your naming rights for the baby," she smirks, nodding at their hands on her abdomen.

He shakes his head. "Not fair, I have just as much right to the naming as you do. I helped create her too."

"You mean him," she says nonchalantly, looking up at him with wide eyes.

"Right."

Laughing, the detective adds, "Anyways, I'm going to have this thing stuck in me for the next six months. I should get to name it. It can even be my Mother's Day gift."

Quickly, his face lights up and he bites his lip to keep from smiling too much. With a "be right back", he places his coffee mug on the bedside table and jumps up.

Beckett laughs. "What has your daddy done this time?" she mutters, her heart leaping. It's still hard for her to believe that they're having a baby.

Castle bursts into the room again, holding a wrapped box in his hands. "It's from me and our little girl," he stresses, handing the package over to her. "Alexis helped as well."

Shaking her head, she loosens the tape on the box and rips the rest open to find a moderately sized book. "It's a baby book," he explains, sitting back on the bed. "You put all your pregnancy milestones and all the baby milestones in here. I was going to give it to you right after I found out but then I couldn't find a good one until two weeks ago and-"

She grins and flips through the pages. "It's perfect."

"You like it?" he asks, surprised.

"Of course," she exclaims, grinning and pulling him closer as if she's going to kiss him. But then she stops, her expression more serious. "You know, this has been the best Mother's Day in a while."

He looks at her like she's the most beautiful thing he's ever seen, and it still makes her blush. "Oh yeah?"

Beckett nods. "Yeah. I didn't think I'd be able to go through one after my mom died and not spend the day wallowing in sadness. And sure, it hurts but now there's Martha and I'll be a mom too and for some reason that makes it hurt a little less."

"I'm glad," he answers honestly, taking his hand in hers and pressing a kiss to her lips. "You know, we could start to fill out-"

"Richard?" a voice calls from the door, and they both sigh.

Beckett speaks first. "We should go meet her."

He groans and lies down on the bed. "I guess," he mutters dramatically.

Trying not to smile at his dramatics, she gets out of bed and tugs on his arm. "Come on. Once she leaves, we'll fill out the book so far."

Tell their story.

For some reason, that makes him get up.
