John wakes up in the morning to hear Rosie giggling away, and then Sherlock’s replies in the distance. He stretches and throws on his dressing gown, leaving Sherlock’s room to join them.
He spies them- Sherlock sitting on the rug cross legged, Rosie in his lap. On the floor are pieces of Lego, and Sherlock is patiently showing Rosie how to build them up, guiding her little hand with his own, and then gently pushing down.
John watches as Sherlock tries to let her do it on her own. She furrows her brow in confusion and then hits the Lego, sending the pieces flying. “Uh oh,” she says, and Sherlock lets out such a wonderful laugh. John’s heart soars.
“Uh oh?” Sherlock imitates. “Is that all you can say? You little rascal! Uh oh!” He scoops her up and half throws her up in the air with a mock growl, and she squeals with joy.
Who’d have thought it, John thinks, remembering that strange meeting from years ago. Me and the ‘madman’ Sherlock Holmes. We’ve made a family.
Sherlock has just settled Rosie back to playing with the Lego, when he spots John. “Oh! Good morn-”
But John is already over and cutting him off with a slow, still slightly sleepy kiss. When they break apart, Sherlock’s cheeks are flushed.
“Oh, a very good morning,” Sherlock confirms. God, John loves it when he plays coy. “What was that for?”
John shrugs with a smile, and bends down to help Rosie build. “No reason. Just- just like seeing you happy.”
Sherlock’s eyes sparkle. He stands and grins. “Well, that’s good, because we’re incredibly happy today, aren’t we sweetheart?” And when Rosie just babbles in response, Sherlock winks at John: “We’ll need double the kisses, then.”
“Ooh, is that right? What’s in it for me?”
Sherlock pretends to look affronted. “More kisses, of course. Oh, and a cup of tea.”
John pretends to consider it. “Go on, then, tea first.”
Sherlock pouts, but John knows he’s still only teasing. “Cheeky, don’t push your luck.”
He almost skips over to the kitchen, reaching up to get the tea bags. “Supervise her building, would you? I was planning to show her how to make Buckingham Palace, but that might be a bit ambitious for a beginner.”
John chuckles and kisses his daughter as Sherlock makes tea. He feels like the luckiest man in the world.
