This I am hoping to expand, but I'm not sure. Anyway, here is chapter one, enjoy :)

"I have a proposition I wish to discuss with you"
Sheldon was sitting at his desk, speaking to Amy on their daily video chat. Today, he had something to ask her.
On the screen, Amy cocked her head, curious as to what Sheldon wanted to discuss.
"Proceed" she nodded
"Excellent" Sheldon took a deep breath "as you know, I have an eididic memory, so from time to time I reminisce on the past"
"I was thinking about two years ago, when we first met, and one of our earliest discussions was on procreation"
Amy sat up at straight..where was he going with this?
"I remember how Penny believed that we should get to know each other before taking such a drastic step, which I believe in the years we have known each other we have done"
Amy's heart began to speed up, her mind racing with various endings to his speech.
"So, I what I am proposing is that we rethink our action to bring a new intelligent species into the world"
Amy couldn't believe what she was hearing. Sure, two years ago it was an idea, but now that they were so close, so connected,it seemed very real. Too real.
"Hang on" she began, staring at the screen "are you suggesting that we..you know.." Sheldon's face convulsed
"Oh Heavens, no. Whilst I agree that we are definitely much closer than two years prior, I still believe that method to be unsanitary and unnecessary with the advancements in artificial methods"
Amy was both pleased and dismayed at the same time. Then another thought came to her.
"You do realise that once the child were to be born , you would have 50% of the responsibly of the child. The feedings, bathing, sleepless nights to name a few"
Hm, he hasn't really thought of that.
"Are you willing to let our work suffer?" Amy continued "There would be no more game nights, movie marathons, comic book Wednesdays"
Sheldon was beginning to see the flaw in his plan. He wasn't ready for it, not yet.
"Amy, I believe you have made some valid points" Amy smiled
"Don't take it the wrong way, I am flattered that you feel I am the suitable mother of the next generation of genius, but the logistics of raising a child are more complex than you think"

"I agree" Sheldon tapped his hand on his head "we need to conduct an experiment"
"What of?" Amy queried
"We need to see if we are suitable for the task of bringing up life that doesn't mean our lives suffer in the process"
Amy nodded "alright, how do you propose we do this"
"Hm" Sheldon pondered "well, I know that my cousin in Texas has recently had a child, maybe we could le.."
"We are NOT 'borrowing' someone's child Sheldon" Amy cut him off sternly.
Sheldon huffed, crossing his arms "fine. What's your suggestion?"
"How about something lower maintenance...a pet of some sort?"
Sheldon's eyes sparkled "you mean like a cat?" He smiled
Amy shrugged "I guess. Young kittens are very similar to newborns, they need to be fed hourly and require a lot of love and attention"
"Then it's settled" Sheldon leaned forward "we shall get a kitten"
"From that, we can see if we are well suited to be the suitable type a newborn genius would need"
Sheldon smiled "I wouldn't say it would be conclusive, but it would help"
"Great" Amy grabbed her phone from beside her "how does midday tomorrow sound for meeting up to go kitten shopping?"
"That would be great, meet at my place?"
"Certainly" Amy tapped it into her calendar
"You know, you should download my iCal to your phone so you know exactly my routine"
"Good night, Sheldon" Amy waved at the screen
"Good night, Amy Farrah Fowler" Sheldon closed his laptop as Leonard entered the apartment.
"Good news, Leonard" Sheldon began as he stood from his desk "Amy and I are buying a kitten tomorrow to see if we are suitable for the upbringing of life, thus hopefully one day we shall create the future generation of genius" Leonard stood silent taking all of it in, a confused look on his face.
"Good night, Leonard" Sheldon exited to his room.
Alone, Leonard sighed.
"Not this again!" He exasperated.
