Week thirty-seven. She'd be due in just a few weeks. The Doctor kept checking and rechecking to make sure that everything was on track. She had to politely tell him to stop giving her checkups after the fourth one. Reluctantly, he decided to run around the TARDIS with K-9 all day instead. They'd do this or that to the nursery or tinker with the medical equipment. He had put child safety equipment on everything. Surprisingly, Rose was the calm one…for now.

"Oi, Doctor. Why'd you have to put a lock on the cupboards?" she called down the hall while struggling with the door.

He appeared with his glasses on the tip of his nose, clearly distracted. "Hmm?"

She tugged on the cupboard. "I can't open it. They won't even be able to reach this high for another few years. You've gone barmy."

"I'm being careful, Rose. See, you just do this…" he did a complicated maneuver and the door magically opened. "What do you need out of here?"

"I need a sauce pan."

He raised an eyebrow. "What are you doing cooking? We already had dinner. Do you want a snack? We could make something! I've just learned this new technique—"

"As fun as that sounds, I'm not trying to cooking anything. I need warm milk since that's supposed to help people sleep. Seriously, I haven't gotten any rest for three nights."

"Insomnia is normal at this stage. Did you nap today?"

"No. I was hoping that I'll be so tired later I'll just fall out."

That caused him to scowl. "I told you to get some sleep."

"And I told you not to childproof the entire blue box, didn't I?"

He smirked at her. "Well, I didn't do everything…"

"Yeah. You did. You've childproofed the loo. Do you know how inconvenient that is for someone my size? Have you ever been pregnant with two kids?"

"Actually, there was this one time…"

"Don't even start, Doctor."

"Oh, all right. I'll go fix the loo."

He grinned as she pecked him on the cheek and they went their separate ways. She warmed the milk and he undid the childproofing. After that, the robot dogs got yet another upgrade, fifth one that week, and he checked the time. The night cycle had just started, so he happily went off to bed. Rose was already there with a mug of warm milk. He crawled in beside her and she kept sipping.

"Tired yet?" he asked her as he flicked off his lamp.

She sighed. "Not at all."

"Try to sleep. You need it."

"I know I do. Tell that to the girls living in me."

He leaned in to her tummy. "Give your mummy some shuteye, Sarah and Hannah!"

She giggled. "Let's hope they listen."

Slowly, she worked her way under the sheets and turned off the lights. In less than ten minutes, the Doctor was asleep. She wasn't. The babies were stretching and moving and her mind was alert. In her head, she tried counting sheep. That didn't work. It made her think about taking the kids to a petting zoo someday. She tried to ride it out, but she got another one of her pregnancy leg cramps.

Gracelessly, she got out of bed and stretched it by wandering the TARDIS. Even K-9 and Powell were shut off for the night. She made more warm milk and it did nothing. After that, she went to the movie room and tried to watch a documentary on the civilization of Ancient Egypt. It was one of the Doctor's top films, but she had always found it boring. Usually, she was asleep thirty minutes in. She watched all two hours.

She poked her head into their bedroom. The Doctor was out like a light. He didn't need as much sleep as she did, so of course he'd be the one peacefully zonking. She paid a visit to the garden and sat with the flowers for a while. Still not tired. She went to the swimming pool and put her feet in the warm water. Not even a little tired. She visited rooms that she had never seen before, but all it did was keep her awake.

Eventually, she wound up in the nursery. She read through all of the children's books they bought with no tiredness. Idly, she wound up the mobile over Sarah's yellow crib. Then, she sat in the matching rocker and rocked back and forth. It played Twinkle Twinkle Little Star, which was the bedtime song they picked. She held onto one of the teddy bears, still rocking.

"There'll be two babies in here soon," she told the TARDIS with a smile. "Just a few weeks."

That's when it hit her. They were going to be parents. They were actually going to have children. She stopped being calm. In fact, she panicked. She ran—as much as she could—into their bedroom.

"Doctor!"

"What?" he mumbled sleepily.

"We're going to be parents."

"Really? This is news to me."

"Shut it. I'm serious. It's not long at all. Us. Babies. Two. On the TARDIS. Parents. You. Me."

"Us. Sleep. On the TARDIS. Need. It. Badly."

She groaned and turned on all of the lights. He pulled the covers over his head and she pulled them back down. With a sigh, he sat up and attempted to get alert. When he saw her face, he understood the situation completely. It was the first time it had really hit home for her that the pregnancy was almost over.

"Doctor, what if I'm not ready for this? We didn't exactly plan it. I didn't think I'd ever be a mother. This just kind of happened. No warning. No anything. And we're getting two at once. What if I make an awful parent? What if they hate me? What if I make so many mistakes I screw them up for life?"

"Rose, it's going to be fine. You're going to be a brilliant mother. We will make mistakes, but we won't screw anybody up, all right?"

"I just don't know if I'm ready. Can they stay in there for a bit longer?"

"Well, we do have a few weeks. That's plenty of time."

She frowned, deep in thought. "You really think I'll be good at this?"

"Oh, most definitely. Do you remember when I told you that you made me better? Brought me back?"

"I do."

"If you can teach someone that's centuries old how to live again, you can teach a couple of children where to start."

That got her smiling. "Yeah?"

"Yeah. Have you slept at all?"

"No. I watched that entire documentary about Egypt."

He looked completely shocked. "The whole thing? You can't get past the first half hour."

"I know! I've wandered the entire TARDIS too and I'm still not tired."

"Well, I've had my rest. Let's go to the console room for a bit."

After grabbing them both a robe, he took her by the hand and dragged her to the console room. He entered something into the system and then opened the TARDIS doors. They stood in the doorway to watch a nebula for a while. Once that got dull, they watched a few late night talk shows streaming live from Earth. Suddenly, the night cycle ended and he looked up at the lights. Silently, he held out his hand. "C'mon then. Back to bed."

"But…doesn't this mean it's morning?"

"On the TARDIS, it's whatever time you'd like it to be. Let's sleep for a few days. We're going to need it. Unless, of course, you'd like to watch another documentary about Egypt. Can't get enough learning."

She took his hand and chuckled. "No thanks. Our poor children. It's going to be learn learn learn all the time."

"Not all the time. My intention is fun. Fun fun fun all the time."

"But you think learning is fun."

He frowned. "You've got me there. Would you like to hear a lecture on the life of amoebas?"

"Why on Earth would I want to hear that?"

"It'll get you to fall asleep, won't it?"

Rose smiled as they got back into bed. She put her head on his shoulder and he began the dissertation. It wasn't five minutes later when she began to snore. He held her tightly with a smirk.

"Goodnight, Tylers."
