He shrugged off his jacket, draping it over the back of one of the table chairs, and set his keys down gently, so not to wake his sleeping wife.
Rose was lying curled up on the couch, sound asleep; her pregnancy was taking its toll on her and there was a baby names book lying half open on the floor from where it had dropped from her grip. Her heavily pregnant belly protruded from her usually slender frame, and her hands were curled around it protectively.
The human Doctor smiled as he knelt beside her, examining her face. This was the only time he could; any other time she'd catch him staring at her and turn away, or pull a ridiculous expression. Unlike other pregnant women he'd seen, Rose's face was actually thinner than usual, and dark circles were starting to show under her tired eyes. He sighed and caressed her cheek, thankful she was at least able to get some sleep.
Getting up, he pressed a soft lingering kiss to her warm forehead, seized a blanket from the other couch and draped it over Rose, tucking it around her bare feet. She didn't even stir as he picked up the book she had dropped, lifted up her legs and sat so they were resting across his lap.
"Time for some you and me time, baby," he murmured softly, lazily tracing old Gallifreyan circles on Rose's belly in which his own child was growing. He hummed a lullaby from his own childhood; so long ago, but it had never left his memory. Then under his fingers, he felt a kick from his child. Rose twitched and shifted in her sleep, mumbling incoherently under her breath.
"Better not do that again, baby," the Doctor whispered, stroking her belly softly. "We don't want to wake Mummy... she's very tired," he said quietly, his gaze flicking to Rose's peaceful face. "You're so energetic, you see; and all your acrobatics keep Mummy awake when she's supposed to be sleeping." Their baby kicked again and the Doctor held his breath; Rose turned over with a sigh, her fingers unconsciously spreading over her belly, feeling their child kick. Thankfully she remained asleep; she had turned inwards, facing the back of the couch, and the Doctor felt his one heart twist as he brushed away the blonde locks that had fallen across her pale face.
He started humming again, a different lullaby this time as he stroked his wife's hand gently, twining his fingers through hers. He sat contentedly and leaned down, resting his head on the back of the couch, watching Rose sleep.
"Rose Tyler," he murmured with a chuckle. "Who've thought we'd end up here? Settling down... we've even got a mortgage." He chuckled again, remembering how they'd joked about it back on the impossible planet. The idea back then had terrified him... this time he had no choice. Of course, it would be completely unbearable if he didn't have her. Rose Tyler, the one person who was constantly saving him.
"You are amazing, Rose Tyler," he whispered, and leaning down, pressed his lips to her limp hand. "You are perfect." He placed his other hand back on her belly, caressing it softly. "And you will be a wonderful mother."
