A/N: So, of course with my luck just after I start this the imagineyourotp Tumblr announces it is shutting down. Of course. Well, good thing is I saved a bunch of prompts in a Word document on my computer, so I'll keep using those until they run out. If you guys know any good prompts, don't hesitate to send them to me via private message. They may get the creative juices flowing.

Disclaimer: Don't own the show, don't own the characters, don't own the chapter titles.

Prompt: Imagine your OTP telling their child that he/she is going to have a little brother/sister.

"Hey honey, can Daddy and I talk to you for a sec?"

Penny peeked into her daughter's bright pink bedroom. Six year old Caroline Hofstadter looked up from the chapter book in her lap – Caroline had always been obsessed with books, ever since she taught herself how to read basic words at age two – pushing a piece of blonde hair that had fallen out of place behind her ear. She really was the best of both her parents - with Penny's looks and Leonard's brains; she really was smart and beautiful.

"Sure, Mommy," Caroline said, putting her book down on her bed and standing up. Penny extended her hand and the little girl grabbed it, interlocking her small fingers with her mother's larger ones.

Leonard was still putting his stuff from work away when they got into the living room. "Daddy!" Caroline happily proclaimed, breaking away from Penny to go hug her father. Leonard was one of Caroline's favorite people in the whole entire world, and honestly, Penny didn't mind. She thought it was sweet her daughter was such a Daddy's girl. Plus, Penny couldn't blame her; Leonard was one of her favorite people too.

"Hey," Leonard said, giving Caroline a kiss. "How was your day, baby girl? What did you do in school today?"

"Good!" Caroline happily announced, following Leonard into the kitchen and sliding into a seat at the table. "We colored, and played on the swings. It was my turn to be line leader. And I hung out with Jessica after school. And we played with her new baby brother."

At this, Leonard and Penny exchanged a look, knowing this was their chance to bring it up. They sat down across from Caroline, who looked back at them with big, brown eyes. "Caroline, honey," Penny began. "We have something to tell you,"

Caroline looked confused. "Did I do something wrong?" She could obviously sense the seriousness of this conversation.

"No, nothing like that," Leonard assured her. "It's a good thing, we promise,"

"Just know that we'll always love you, Caroline," Penny chimed in. "And you'll always be our baby girl," Caroline nodded.

"You're…" Leonard began. "You're going to be a big sister,"

"Like Jessica?"

"Sure," Penny agreed. "Like Jessica,"

Caroline mused over this for a moment, not saying anything. "Where is the baby?"

"In Mommy's tummy," Caroline nodded as Leonard explained this to her. She had noticed that her mother had gotten a little bigger – it made sense. "And then by spring, when the baby's big enough, you'll have a baby brother or sister."

Caroline, inquisitive as ever, tilted her head to the side as she absorbed this information. "How did the baby get there?"

Penny tried to stifle a laugh (and failed), while Leonard got a deer in headlights look, confusing Caroline. It was just a simple question…"We'll umm, tell you later," Leonard choked out once the color had come back to his face.

Caroline shrugged in response. "Okay," She said. She jumped down from her chair and hugged Leonard. "I love you Daddy," She moved over to Penny, wrapping her arms around her shoulders. "I love you Mommy," And finally, to Leonard and Penny's awe, she gave Penny's stomach a hug. "Love you baby!" Then, Caroline marched back into her room, probably to go finish her book, as if nothing had happened.

At this, Penny started laughing again.

I didn't proofread this because I'm short on time, so sorry if there's a typo or something.
