"Daddy?" the five-year-old asked.

"Hmm?"

"Mommy has two babies in her tummy, right?"

"Yep." Gregory House looked away from his gameboy and smiled at his lovely little daughter.

"How'd they get there?" Greg felt the blood drain from his face. "Daddy? How'd the babies get there?"

"Well, you see, Liv..." Allison chuckled lightly from the kitchen. "When Mommy and Daddy kiss...no...When a man and...no...I'll tell you when you're older."

"You don't know how they got there?"

"I know how they got there, Olivia. I'm a doctor." Liv raised an eye brow and Allison laughed at the situation. "Ask your mother. She's a doctor, too." Allison glared at him.

"Hey, Mom? Same question."

"Mommy kissed Daddy, Daddy told God, and God put them there."

"Mom?"

"What?"

"That's a load. Daddy doesn't believe in God. Neither do you." Greg groaned. "What's the big secret? I know where they come out. I just wanna know how they got in!" Greg pulled his daughter up on the couch next to him.

"Olivia, when two people love each other very much, and they are over 35...remember that number...35. When they love each other and they are over 35, they sleep in the same bed. If they really love each other, things happen in the bed and they have a baby about 9 months later. There are requirements; you have to be over 35," he stressed. "There has to be a man and a woman, and it may NEVER happen while we are in the same house." Allison couldn't hold the laughter in anymore, and fell into a giggling fit.

"I have to be 35? That's old!"

"Hey! Its not that old, Olivia," Allison called as the child ran off to play in the yard. "Greg? 35?"

"I do not want to have a teenage parent on my hands. If I teach her now 35, maybe she'll wait until she's 25."

"Doubt it."

"Dammit." He rubbed the bridge of his nose. "Can't we lock her up for puberty?"

"We can make her do paper work at the hospital..."

"Cuddy'll love that."

"Our parents survived out teen years, we'll live through theirs." Allison maneuvered herself onto the couch. "We have two great kids, Gregory."

"And in 4 months, we'll have 4 great kids." He rubbed her belly, and was rewarded with a swift kick to the hand.
