"Rose. Rose. Rose. Rose Tyler. Rooose," the Doctor whispered into her neck. "Wake up."

She stirred slightly and yawned, happy that week thirteen brought no morning sickness. It wasn't rare for her to get sick later in the day, but at least she didn't have to leap out of bed every morning…the bed she now shared with the Doctor in their room.

"What?" she asked groggily. "What is it?"

"You slept through the alarm clock. Again."

She grumbled and burrowed into the blankets further. "Uh-huh. That's nice."

"Rose. Rose. Rose—"

"What?"

He grinned widely. "Hello."

"Hi…" she smiled hazily and glanced down at her huge baby bump. "Doctor, I have news for you."

That got his attention. "News? What kind of news?"

"What we did last night…it might have gotten me pregnant."

"Blimey, are you sure?"

She nodded against his chest. "I'm afraid so. Just look at me."

"Well, that is something."

"Isn't it? Hope this wasn't too big of a shock."

He maintained his serious expression. "It was, actually. Quite a shock. I had no idea we'd wake up expecting. And after one night together."

"More like six or seven by now."

"Eight, but who's counting?"

Their eyes locked and they burst into fits of giggles. She pointed at him. "I'm impressed. Not even a smirk! I was sure that I'd get you to laugh before now."

"You faired quite well yourself. You're a professional."

She made a grand gesture. "A-thank you."

He pecked her on the forehead and placed a hand on her bump. "Good morning, little one."

"D'you notice how big I am? I look like I could deliver any day and I'm not even out of the first trimester. Is that a Gallifreyan thing? Being bigger? Or does this just mean that I have one huge baby?"

He chuckled. "I don't know, actually. You're due for your next checkup, so why don't we do that?"

"Right now?"

"No. Certainly not now. I'm comfortable," he snuggled closer and flicked his tongue across her jaw. "Very comfortable."

Once they were awake and ready to move, which was much later, they went to the medical bay and he prepped a few tests. He did a few routine scans to make sure Rose was healthy, and then he decided to do tests pertaining to their child. She leapt at the cold goop on her tummy, and then waited for the Doctor to do whatever it was he was doing.

"First things first. Would you like to hear our baby's heartbeat?"

She grinned. "I would."

"Allons-y," he smiled as he applied the tool. They listened and both frowned at the rhythm. "That's not…"

"Is that in beats of three?"

"Beats of six," he answered unsurely. "I'd expect two for the human heart or four for a Time Lord, but six? That can't be right."

"Is something wrong?" she squeaked, growing panicked. "Doctor, is something the matter?"

He shook his head. "I don't think so. It sounds all right. Not a murmur. It's just…six different noises. Let's do an ultrasound."

Turning the screen so they could both see, he applied a different tool and they watched as the first images of their baby appeared. A hand went to her mouth and he was in shock.

"Rose…" he began in amazement. "We're having twins."

"Twins," she repeated as she looked at the two separate fetuses. "How is that possible? They said I was having a child. Singular."

"It must have split. That happens later on in Gallifreyan pregnancy than human pregnancy. But, twins are really rare. I'd bet that when they sped up the process they accidentally increased the chances," he responded. "Twins. Twins. We're having two."

"Does that mean that their heartbeat is in patterns of three? That's why there are six. And that's why I'm so bloody huge."

He had to sit down. "Well, I suppose that in combining our species, the baby…babies…have one and a half human hearts. Instead of just having one or two, it was split right down the middle."

"Okay…" she responded unsurely. "And you said that's fine?"

"Yes, it appears to be functioning properly."

They sat in silence for a moment and stared at the image. "Twins," Rose said again. "Twins."

"Two children. Not one. Two. That means we need two of everything."

"That means twice the trouble."

The Doctor suddenly grinned. "But you do know what this means?"

She shrugged. "Um…two kids?"

"Yes, but Rose. Think about it. We couldn't have children any other way. It'd be impossible. The one time we end up in a lab, the one time we could ever conceive a child, we get two. Before, we'd only have one. That'd be it. No more. No siblings. An only child. But now…they'll have a brother or sister. How lucky is that? It's a freak occurrence. A fantastic freak occurrence. Two children for the price of one! Go to a lab, get one free! Ha! This is brilliant!"

Rose hadn't thought of it that way. Tears welled in her eyes and she smiled. "Two little ones."

"We have shopping to do," he proclaimed as he helped her off the table. "Loads and loads of shopping. Two cots, two changing tables, two of it all! Get yourself ready, Rose. Comfortable shoes, comfortable clothes. We are going to the biggest mall in the universe! If I can dig out my old emergency credit card…"

She folded her arms. "Why haven't you mentioned this credit card before?"

"It's an emergency credit card. For emergencies only. I'd say two of our offspring counts as an emergency, wouldn't you?"

"Yeah, but I'd say that needing new shoes is also an emergency."

"It is not."

"It is if you're a woman and nothing goes with your outfit!"

"Well, the universe won't end because someone's shoes clash with their outfit. Just look at me. White trainers and a pinstripe suit. Universe? Not ending."

They squabbled all of the way to the mall about what qualified as an emergency for credit card usage. Once they stepped into the mall, all was forgotten and they linked hands. Slowly, they ambled through shoppers of all species to find the baby supply shops. Eventually, they found it and wandered inside.

"This is unbelievable!" Rose exclaimed as she gripped his arm. "Just look at all of the things. They have everything we need."

"Yep. That's the idea. Shall we start with furniture?"

Upon reaching the cribs, Rose thought of something. "We don't know whether to buy for boys or girls. Maybe we should have waited."

"No, we should get this out of the way. Take the rest of the time relaxing. We'll just go neutral. I think yellow."

"Yellow?"

"Well, you're pink and yellow. Can't do pink. Not yet, at least. So, yellow it is."

She frowned. "How will we tell them apart? What if they're so identical we mix them up all the time?"

"So we'll go with yellow and something else neutral. What else is neutral?"

Her eyes drifted to a crib with a list of style options. "White like the lettering on the TARDIS. This one comes in both yellow and white."

"Brilliant. C'mon, shop shop shop!"

Once they were finished with the furniture, they went to look at clothes. The Doctor held up a yellow jumper for newborns with a big grin. "Rose, look at this. It's so tiny. I feel like a giant!"

She held up a similar one that was clearly for an alien. "You think that's something? Look at this one. It's for an octopus."

He chuckled and his eyes lit up. "Toys!"

Rose shook her head as he ran towards the toy section. "I'm going to have three children, I swear."

She kept shopping for clothes and wandered off to find the Doctor. He was in the toy aisle with seven or eight toys all around him, clearly playing make believe. She smirked and waited to be noticed. When he glanced up, he smiled embarrassedly. "Well, hello. I was just testing them. Making sure they were safe and enjoyable."

"Right, testing them. You never told me that you like playing with toys."

"Who doesn't like toys? You are never too old for toys, Rose. I'm over nine hundred years old. I don't care. I've got an idea! Here, you be the stuffed cyborg and the ducky. I'll be the puppy and the Ood baby."

He thrust the toys into her hands and she laughed. "I can't exactly sit on the floor with you. Got two kids in me."

In an instant, he popped up and held out his chosen toys. "Now, before you came here there was a big argument. The cyborg says that the puppy ate his hot dog and the ducky thinks that the Ood baby stole his banana. They are all very cross with one another. Oh, and my puppy is Scottish, so he has an accent. Ready to begin?"

She couldn't stop smiling. "Can my ducky be Irish?"

They played for almost thirty minutes, getting many stares from the customers and staff. Somewhere in the middle of the game, the ducky went from being Irish to Indian and the cyborg decided to marry the puppy despite the hot dog drama. After that, they went to the front and got help accumulating all of their purchases. It was clear that dragging them through the mall wouldn't work, so the Doctor ran to the TARDIS and parked it out front.

That night, he set up the nursery furniture while Rose sorted the clothes by outfit and size. They climbed into bed exhausted. Rose couldn't sleep and decided to pay back the Doctor for that morning. "Doctor. Doctor. Doctor. Doccccctor."

He opened one eye. "What?"

"Hello."

"Hello," he smirked in response.

"I have news."

"Let me guess…you're pregnant?"

She rolled her eyes. "I already told you that this morning. I have different news."

"Really?"

"I saw the Doctor today."

He nodded slowly, seeing where this was going. "Did you? I'd imagine that he's a clever and attractive bloke."

"Eh."

"Eh? Eh? That's all?"

"Shut up. I'm only messing with you. You're not letting me tell you the news."

"All right, what's the news?"

"We're having twins."

The Doctor pretended to be shocked. "Are you joking? We're having two?"

"Yep. Two. Just thought that I'd tell you."

"Quite right too. I had no idea whatsoever. Now, you should get your sleep while you can, Rose Tyler. One baby is hard. I hear that two at once is just mental."

She kissed his check and set her head on his shoulder. "Two of us, two of them. I'd say we're even."
