How would Mycroft end up babysitting to begin with? I feel like he’d want to interact with Sherlock when he’s small because it’d let them both be as affectionate as they want without their usual reservations. Jawn would be incredulous at best about My. At least at first.

Sadie: That’s a very good point. John would fight tooth and nail to keep that ‘tough guy’ exterior up around Mycroft…his is not a baby, should anyone need to be reminded. But, Sherlock *does* look awfully content to sit in his older brother’s lap. And Mycroft, while still being his normal stuffy, proper self, doesn’t sound as nearly condescending as he usually does. And John is starting to feel a bit left out.

“Bee’, bee’, bee’,” Sherlock chanted back, reaching up to poke at Jawn’s nose causing the little Doctor to fall over in a giggle fit. They laid on the carpet poking at each others faces.

“Is there paracetamol in this flat?” Mycroft asked, not really expecting an answer. The beeping was steadily growing in volume.

“Baf’room!” Jawn chirped, leaning in to lick Sherlock’s nose instead of poke it. “Boop.”

Sherlock froze in place, hand inches from Jawn’s nose as he processed his damp nose. Sensing the impending doom, and unwilling to leave them on their own again after the last time, Mycroft came into the sitting room and pulled them to their feet.

“I’ll never be able to find it on my own. I need the world’s greatest detective’s to find it for me.” Mycroft tried to usher them toward the bathroom, but it was like wrangling cats. Jawn squirmed around him and made to the stairS

“Sher’yock needs his hat!”

“Nooooooo hat!” Sherlock cried, covering his head with his hands.

Sadie:

“Sherlock does not need his hat, and Jawn does not need to climb those stairs!…JAWN.”

The little doctor froze, one foot already on the bottom step, and looked at Mycroft over his shoulder.

“Neither of you are allowed on the steps while you’re little.”

“But–“

“I said no.”

Jawn took a step back, and stomped his foot. “But My! He needs it!”

Mycroft looked down at Sherlock, who still had his fingers locked together over his head. “He doesn’t want it.”

Jawn’s face began to grow red, and he stomped both feet until he’d turned in a complete circle. “But MY!”

Sherlock clutched the back of his brother’s waistcoat in a tight fist and watched the goings’on while quietly sucking his thumb, not wanting to draw attention on himself. Mycroft sighed, and rubbed his temple. This one was going to be a doozey. “Jawn, one more time, and I will spank your bum.” Hell, Sherlock had already earned two on his own, why not go for a three-fur?! Still…Mycroft held out his hand; “Come on, Jawn…help us look.”
