"I don't think she likes the bananas," Donna said, watching their daughter smear pureed bananas over the tray of her high chair.
"Nonsense, of course she likes them. She's just having a bit of fun, learning about textures and all that," the Doctor said, horrified at the thought that his daughter might not like bananas.
"And what's she doing now?" Donna asked, as little Mary rubbed the bananas into her hair, smiling broadly at both of them.
"Trying to see whether we'll stop her fun, I should think," he answered, smiling at her indulgently.
"Well, you can give her a bath after."
Mary stuck her fingers in her mouth, sucking off the banana mush. She made what the Doctor considered an approving noise, and he laughed.
"See, she likes it!"
Mary chortled at him, waving her hands enthusiastically, managing to fling a dollop of banana onto the Doctor's nose. Donna laughed, and wiped it with her finger. He grabbed her hand, and stuck her finger in his mouth, noisily removing all traces of the banana. "Oi!" Donna protested, but he silenced her with a kiss, broken only when they heard the unmistakable sound of Mary dropping the bowl on the floor.
"Ha!" Mary said, quite clearly.
"Ha, baby," Donna said. "Daddy's going to clean you up now." She kissed the top of her head as she rose. "Be a good girl."

Bathtime done, and all traces of banana removed, he sat in the rocking chair, humming tunelessly, watching her sleep. His daughter. Her tiny hand curled around the blanket and he touched it, smiling.
Donna appeared in the doorway and smiled, watching him. She moved to perch on the arm of the chair, leaning down to kiss him.
"She looks just like you," she said, "except ginger."
"Well done, I think."
"Don't you forget it."
He patted his lap. "There's room for both my girls."
She slid down, curled around them both, rested her head against his shoulder. He hummed again, rocking gently.
