I wanted to try the Lodger scene but with Jackie so here it goes:

Jackie Tyler, sleep deprived, taking a second lap around the motherhood circuit, was up at three AM for the fourth time this week.

"There, there, you little grump." She told the two month old tenderly. Somehow, the first time around had been easier. She'd at least had more energy to clear the task of child-care. "Oh, Tony." She had to be up at a reasonable hour but she'd been pacing with him in the large marble foyer for half an hour to prevent anyone else from waking up. She sighed, closing her shadowed, blue eyes.

"Let me try." Jackie nearly jumped at the voice behind her. It was the Doctor, or the Doctor of this alternate universe. He himself looked tired, he-along with Rose-had been logging long and hard hours working with UNIT. The Doctor-John Smith, had assured the Tyler family he was fine-that he'd gone days, weeks even, without sleep. "That was while you still had two hearts", Rose had reminded him. Personally, Jackie still thought he wasn't getting enough sleep either. His hair lay flat against his head, his alien version of bedhead. Under his eyes were a little darker, and he was looking just a bit thin (so much wasn't new) in his blue pajamas.

John and Rose had moved into an apartment across town-closer to work. It wasn't often that they were about at night time, much less sleeping over. Jackie nodded at his question, tucking the blankets around Tony before placing him carefully in John's arms.

"Aw, are you tired now?" He said, his Scottish accent thick and excitable.

"John, don't you go riling him back up!" Jackie scolded. "I just calmed him down."

"Not according to Tony, you aren't." John Smith brought the baby closer to his ear. "Now is that right?" He looked back up at Jackie. "He says he gets cross when you call him grumpy. He thinks you're the grump. And he wants his old brand of diapers back."

Jackie stared at John blankly.

"Oi, you're a bit bossy, aren't you?" John asked. "Just like your mother."

"Oh come on, now, stop messing around." Jackie huffed, trying to take Tony back from him. John leaned back a bit.

"Will you be quiet for your mummy if I make you a really cool star-star?" John looked up at Jackie and stage whispered. "That's what he calls a mobile."

"Oh, of-" Jackie stopped. The crying had stopped, hadn't it? The only noise left in the house was the gentle trill of John's nonsense warbles to Tony. She was stunned.

"You speak baby?"

"I speak every language. Of course I speak baby." He explained, tickling Tony's chin. "You've got quite a future trouble-maker here, Jackie." He smiled, kissing the calmed boy's little cap.

"Trouble-maker, huh?" Jackie smiled, taking the yawning Tony back in her arms. "I've got three now, don't I?"
