Me and Ms. Watson

"Sherlock?" John called walking into 221b

"Yes?" Sherlock said

"Where here" John said

"We?" Sherlock said looking away from the microscope

"Yeah, me and Lydia. Your babysitting her for a few days for us. Remember?" John said walking in the kitchen holding Lydias carseat and a bag

"Thats this week?" Sherlock said

"Yes Sherlock. It is" John said rolling his eyes

"Hmm...well I'm busy so i can't" Sherlock said

"I wouldn't call examining eyeballs as 'busy'" John said

"Im not sure why we agreed to me watching your offspring, Lestrade can call at any moment with a case. What would i do with it then?" Sherlock asked

"Leave HER with your mother for that time, or call Mycroft, I'm sure he'll be able to get a nanny" John shrugged and put emphasis on the word her

"Why can't Mrs. Hudson just keep it for the time that your gone. She's a woman she knows more about children than i do" Sherlock said and John sighed

"Because i asked her and she said she was busy this week" John said setting the carseat on the chair at the table and Sherlock sighed

"How long are you and Mary going to be gone?" Sherlock asked

"Just three days. Im sure you'll manage" John said and Sherlock nodded

"Very well" Sherlock said

"Alright i better be going. You can call me anytime and knowing you i will be receiving calls daily. Don't corrupt our daughter please, don't do any dangerous experiments while she's here" John said

"Well thats just not gonna happen" Sherlock said crossing his arms and John frowned

"Please. Whatever you do, just make sure she's not in harms way" John said and Sherlock nodded

"Laurie will not be involved in any experiment John" Sherlock said

"Lydia" John said

"Hm?" Sherlock asked getting up and going over to his chair

"Her name is Lydia, not Laurie" John said taking his daughter out of her seat and walking over to Sherlock

"Mm...yes. Well either way, she'll be fine" Sherlock said and John glanced at his daughter before putting her in Sherlocks lap carefully and pulled out some paper

"Here. I wrote up some notes for you that tells you how to care for her. You know, when she eats, when she sleeps, stuff like that" John said and Sherlock took the paper and set it down frowning at the baby in his lap as she squirmed

"Like you said. I'll manage" Sherlock smirked at him

"Alright. You be good Lydia, i'll see you in a few days. Call me if you need to Sherlock" John said leaning down to kiss Lydia and glared at Sherlock, who nodded and then John left

"Alright Leah, lets just set you down" Sherlock said awkwardly and laid a pillow on the floor and put Lydia on top

Sherlock had tried his best to focus on his thinking but Lydia kept crying. He eventually picked her up and sat with her and that did nothing to fix the situation. After a while his phone beeped and he looked at the text, it was from Lestrade and it read: Body found in locked car and no murder weapon was found, west street -GL.
