Amy was panting, and she grabbed Sheldon's hand tightly.

"Okay Amy, you're going to need to push hard for me." One of the paramedics said, looking up at her.

"I need some pain medication…Or gas and air. I can't do this on my own!" Amy wept.

"You're not on your own; you have Sheldon and me." Penny soothed.

"But I need pain relief." Amy shook her head, and then screamed.

"This baby isn't waiting for pain relief Amy; it's coming now." The midwife apologised.

Amy cursed loudly, then turned to Sheldon. "Do you have anything?"

Sheldon frowned, thoughtfully.

"I have wine?" Penny offered.

Sheldon shot her an angry look. "Must you!?"

He looked back down at Amy. "The best I have is Aspirin and Paracetamol, which will be less than useless." He said, sadly. "You're almost there, you can do it."

Amy pushed a little harder, but then stopped. "You're forgetting that there is another baby after this one!"

"I'm forgetting nothing. But we can do this…I'm here. What can I do to help you?"

"You can sing Soft Kitty…"

Sheldon blinked. "You told me that you didn't want me to."

"Yeah, well now I do. It's soothing." Amy responded.

Sheldon looked embarrassed as he remembered that the midwife and two paramedics were in the room. He bit his lip.

"I'll sing it with you." Penny offered.

"I'll get a wet rag for Amy's head." Sheldon said, hurrying away to grab a cold, wet flannel and some ice in a tumbler, which he helped Amy to drink from.

Placing the flannel on Amy's head, Sheldon took a breath.

"Come on Amy, not much further. The baby is crowning." The midwife spoke up.

"Okay, I'll count us in. Ready?" Penny asked.

Sheldon nodded.

Penny cleared her throat; "One, two, three…"

"Soft kitty, warm kitty, little ball of fur,

Happy kitty, sleepy kitty, purr, purr, purr…"

Penny and Sheldon harmonised, then looked at Amy, who seemed a little calmer now.

"We have the head, Amy. Keep going!" One of the medics said.

"Go again." Amy requested, crying in pain.

"Soft kitty, warm kitty, little ball of fur,

Happy kitty, sleepy kitty, purr, purr, purr…"

At that moment, a cry filled the air as the first twin was born, and Amy slumped back on the pillows against the couch, gasping for breath.

The medics cut the baby's cord and Dr Crispin washed it in the baby bath, before swaddling it in one of the warm towels and handing it to Amy.

"This is your first twin; the little boy!" The midwife smiled.

Penny ran to the bathroom to change the water in the baby bath, and returned just as Amy was about to deliver twin number two.

Dr Crispin held the little boy as Amy began to push again.

"I'm too tired." Amy cried, shaking her head.

"Come on Amy. Just once more and then you will never, ever have to do this again!" Penny encouraged.

"Uh, hang on now, we haven't established that yet!" Sheldon spoke up.

"Shut up!" Penny hissed.

Sheldon rolled his eyes and laced his fingers through his wife's. "Come on beautiful." He whispered.

"Amy, you're doing really well. Just two more really big pushes and your little girl will be here." The paramedic encouraged.

Tears began to fall from Amy's eyes, and she shook her head. "No. I can't…"

"I wish I could do it for you." Sheldon said, "Squeeze my hand as hard as you can when you push, okay?"

Amy nodded and tried again, and squeezed Sheldon's hand.

"That's good…Nice firm grip you have…Okay, Amy? You're kind of crippling me here!" Sheldon was sinking to the floor in pain as Amy almost broke his hand by squeezing too hard!

"We have the head and shoulders now…One more!" Dr Crispin called, "well done Amy, almost there!"

Amy pushed once more, making Sheldon's hand crack as she squeezed it.

"Ohh Lord! That's done it!" He cried.

The second twin was finally born, and Amy collapsed against the pillows again, panting.

"Well done Amy, good job!" The midwife grinned, as the little girl's cord was cut and she was cleaned in the baby bath.

Sheldon leaned down and kissed his wife lovingly.

"I'm sorry about your hand." Amy said, almost deliriously.

"Oh, that's okay…" Sheldon replied, uncertainly, studying it in front of his face. "The babies are here, that's all that matters."

"And here's your little girl." Dr Crispin handed Amy both twins, wrapped in different coloured warm towels.

"Do you have names for them?" The paramedics asked.

"Grace and Sam." Amy smiled.

"Those are perfect names!" Dr Crispin smiled.

The medics and midwife helped Sheldon and Penny to clean up, and dispose of soiled sheets and towels, helping move Amy and the twins to the bed.

Once Amy and the twins were checked over, the medics and midwife left.

"I'll be back tomorrow to check on you. If you need anything, give me a call." She smiled.

Amy nodded and thanked them all as they left the apartment.

Sheldon sat on the other side of the bed, next to Amy, his legs outstretched.

He took his turn to hold the babies, and smiled.

"They're not identical in the slightest." He commented. "It will be easy to tell them apart."

Amy chuckled. "It will be easy anyway…one has a penis!"

Sheldon just laughed, as he handed Grace back to Amy and took Sam.

"I can't believe I have a son," he said softly, "I had a horrible feeling I'd be surrounded by girls!"

"You still are outnumbered by girls!" Amy grinned.

Penny knocked on the door, and Amy called for her to come in.

"I brought Leonard, is that okay?"

"Of course; come in. This is Sam and this is Grace." Amy gestured to each twin.

"Aw! They're so cute! Hello little guys." Leonard bent down to look at them.

Both of the babies had their eyes closed and were making cute little noises.

"Aww! They are so adorable, aren't they Leonard?" Penny grinned.

"Mommy?" Izzy's questioning voice cut through the air, and the grown-ups all looked around to see her stood at the door, with Robbie peering behind her.

"Come meet your new brother and sister!" Sheldon said, walking over to pick Izzy up and place her on the bed. "Be careful, though."

Isabelle smiled at the twins. "Hello babies!"

Robbie stood shyly behind Penny.

"This is your sister Grace." Amy said, and Izzy dropped a kiss on her new little sister's head.

"Oh! That is so cute!" Penny said, her eyes misting over.

"And this is your brother Sam." Sheldon said, ad Izzy repeated the action for her brother.

"The baby brother you predicted, my little genius!" Sheldon grinned.

"So what do you think, Izzy?" Amy asked.

"I love them." The toddler replied.

At that moment, Penny burst into tears, and everyone looked at her.

"Oh my God. Leonard, we have to have another baby." She said.

Leonard blinked, shocked. "What, right now?!"

Everyone laughed.

..

Twelve years later…

"Sam!"

The dark haired boy looked around, his bright blue eyes dancing mischievously. "Yes?"

"What have I told you about going into my room?" Izzy folded her arms.

"Um…Don't?"

"Right! So please inform me as to why my book on Halogens is missing?"

"Um…"

"Forget it Izz, he won't admit it." Grace sighed, standing beside her older sister.

"I am starting college next week; I need all of my books!" Izzy complained.

"Well that's your fault for starting college before everyone else." Sam argued.

"How is that her fault? We got put up two grades last year, and are about to be put up again into junior year, so you can't talk about being too advanced!" Grace countered.

"What is going on in here?" Sheldon walked into the front room of the 5 bedroom house that the family now owned.

"Sam stole my book on Halogens!" Izzy grumbled. "I start college next week and I need it!"

Sheldon sighed. "Sam, Isabelle needs that book."

"Well I need it too!" Sam said.

"I'll get you and Grace a book of your own when we go to the mall later, if you behave. Now, please give it back."

Sam rolled his eyes and got to his feet.

Amy walked in, drying a mug with a dishtowel. "What's going on?"

"Sam stole one of Izzy's books." Sheldon replied, giving his wife a kiss on the lips.

"Ugh, gross! How you can kiss another human being is beyond me!" Sam wrinkled his nose as he returned with the book, which Izzy took off him immediately.

"Oh what? Cause all girls have 'cooties' right?" She snorted.

"No. Because public displays of affection are pointless and why would you want to exchange saliva with someone? Gross!" Sam rolled his eyes.

"I used to think the same, and then I met your mother…" Sheldon started.

"Yeah, don't care. Another vom-fest, Dad. I'm going to my room. I have a senior calculus paper to ace. Later." Sam waltzed off again.

Grace exchanged a look with her older sister. "I've already finished mine."

Izzy grinned at Grace, who shook her dark brunette hair back and flounced off.

"Wow. If I'd have known that our children would grow up to be so academically competitive with each other, to the point that they'd disturb the peace, I may have reconsidered getting pregnant." Amy joked.

"I see it as a learning curve, and you know how much I love learning things!" Sheldon replied, lacing his fingers through Amy's.

She smiled. "Definitely! So Izzy, have you chosen a major yet?"

"You know it will be chemistry. I want my doctorate as soon as possible, to go into a Physical and Theoretical Chemistry job." Izzy replied.

"That's great! Minors?"

Izzy frowned. "I was contemplating minoring in Prehistoric Archaeology. You know how much I love dinosaurs!" Her blue eyes danced as she talked about her passion. She glanced at her watch. "Oops! I have to go pack. See you at dinner!" She bounded away, her long, dark hair glistening.

Sheldon and Amy just stood proudly next to each other for a while, smiling as they watched their three overly-advanced children hurry back to their studies.

"I can't believe we managed to produce three prodigies!" Amy smiled.

"Well, when their parents are both geniuses, it was bound to happen." Sheldon replied.

"Now, are you sure you'll be okay if I meet up with Leonard, Raj and Wolowitz?"

"Of course. Penny, Bernadette and Brigitte are coming over anyway. They'll take care of me." Amy smiled.

"Good." Sheldon grabbed his keys and bent down to kiss Amy's rounded stomach. "Bye little guy." He smiled, then straightened up to kiss Amy on the lips. "See you later. I love you."

"I love you too." Amy watched Sheldon wave and walk out of the door to greet the guys who were waiting outside.

"MOM! Sam went in my room again!" Izzy shouted down the stairs.

Amy shook her head, smiling to herself and closed the door.
