Sadie: Babylock headcanon #8569: Greg is one of those people who nicknames everyone; “honey”, “sweetie”, “darling”, etc. The boys and Mycroft each have multiple ones that he uses on them, but Jawn is usually ‘Monkey’, Sherlock is ‘Muffin’, and Mycroft is ‘Sweetcheeks’.

Greg rubbed Mycroft’s back as he snored. He’d caught a bug
from the boys that had left him with a rattling chest for ages after Sherlock and
Jawn had been whole and hale again. Greg could hear Sherlock over the baby
monitor chattering to his bunny about all the fun things he was going to do
with Da’yee and My’coff and his y’ub bug. Christ. If Sherlock brought a live
bug into the house, Mycroft would have kittens. “Nap times over,” Greg patted
Mycroft’s bum, “I’ll go get the baby up.” Mycroft responded by snoring all the
louder.

Greg switched off the baby monitor and headed down the
hallway to the nursery. Keen ears had heard him coming and Sherlock was
kneeling up the crib, bum waggling like a puppy. “He’yyo! I miss’t you! We can
ha’b ad’bentures now?” Sherlock shouted, stretching his arms for Greg.

“Hello, sweetie muffin. Did you have good sleep?”

“I dun y’ike id!” Sherlock crowed, grinning ear to ear.

Greg slid the side of the crib down and promptly had an
armful of baby, “you silly guy. I know you like naps.”

“Noooo,” Sherlock squeezed Greg. “We ha’b ad’bentures, y’ub
bug?”

“Where’s a bug? Mycroft will be really cross if you brought
a bug in the house. You know how he is.”

Sherlock laid back on the changing table, twisting a finger
in his curls. “My’coff y’ike y’ub bug. My’coff y’ub y’yub bug,” Sherlock said
with a cheeky grin.

“…Love bug is me?” Greg could feel his cheeks turning
scarlet.

“G’eg a y’ub bug,” Sherlock nodded.

Easy ya’ old soppy. Greg smiled down at the baby as he
changed his nappy, “what kind of adventures should my muffin have with his love
bug, hm?”
