My first attempt at any FanFiction so sorry if it poorly written but you gotta start somewhere right. No sexy times in this chapter but there will be sort of in the next.

I unfortunately don't own the characters Conan Doyle, Gatiss and Moffat do

Sherlock attacked the stairs to his flat at Baker Street in his usual 'there isn't enough time in the world' fashion. Opening the door with such gusto it ricocheted off the wall behind it.

"What is that?"

"It's called a baby Sherlock and would you stop making so much noise I'm trying to get her off to sleep." John sighed, pinching the bridge of his nose.

John was sat in his normal armchair in his black and white jumper, what he was wearing the first time he and Sherlock had kissed exactly a month ago. Opposite him was a baby dressed in a pink frock with more frills than was necessary strapped into an infant car seat implying John had no idea what to do with her.

He's been up for 32 hours, 17 minutes and 23 seconds noted Sherlock, though he thought that if he pointed this out it would earn him more sniping from John.

"Yes John, as a consulting detective I worked that out from the odour that thing is poisoning the whole building with before I entered. I just wish to know why you thought it appropriate to put it in my armchair or even keep it in the flat."

"That 'Thing' has a name. It's Zara and it's Harry's child. She came here smashed off her head saying something about adopting a kid not being for her and ran off. Well staggered. What did you expect me to do with her Sherlock? And anyway whoever thought it was a good idea to entrust my sister and that 'Sarah' women with a child deserves to be put in prison for child endangerment."

"It can't stay here John it will distract me from my work and anyway this is hardly a safe environment. And for God's sake do something about that smell."

"I can't. I haven't got any nappies since Harry neglected to bring more than 5. Or enough baby milk for that matter. You couldn't go to the shops could you; I'm not in the mood for a fight with a self service checkout."

Sherlock stormed out of the living room into his bedroom, reappearing seconds later armed with scissors, an old towel, wipes and safety pins. He then walked over to Zara who was sat gurgling in her car seat on Sherlock's chair.

John was immediately stunned into silence. Just when he thought Sherlock couldn't astound him anymore, John found himself making at the makeshift nappy being created by those pale impossibly long fingers.

When speech finally returned to him John asked "How the hell can you not know that the earth goes round the sun but know how to make a nappy the old fashioned way? I can hardly imagine that that snippet of information will ever be needed for a case."

"Actually John I had a case 3 years ago in which a group of Frenchmen smuggled poison into airports by placing it in the folds of the material in a nappy like this. The poison was made airborne when the child urinated..."

"Ok Sherlock it's useful, you don't need to tell me anymore." John shifted uncomfortably. How can he talk about babies who undoubtedly died in such a terribly way and make it sounds normal yet he always manages to be so attentive and loving to me, John thought making a mental note to experiment Sherlock's emotional range.

Sherlock held Zara underneath her arms as far away from him as possibly as if she had some deadly disease despite the fact that he had been changing her nappy a minute ago. He plonked her on John's lap and moved into the kitchen, opening all of the cupboards in an attempt to find the mugs.

"They're in the top right cupboard and don't you dare try to make tea since the last time you tried to modify the kettle so it could heat more water and ended up blowing it up and propelling boiling hot water everywhere. 2 inches from where I was standing Sherlock. 2 inches"

"Killjoy" muttered Sherlock. He had suffered too after that had happened since Mrs Hudson had refuse point blankly to letting them use hers in a failed attempt to establish that she was just their landlady and John had selfishly been too I'll to go out and buy another one.

He moved back into the living room, throwing himself onto the sofa with his hands steepled in their prayer position. There was a knock at the door to which he simply said 'Jooooohn" keeping his eyes closed.

John sighed and put Zara back into her chair. As he had expected it was Mike at the door with a fold up cot, toys, nappies and a box of baby milk powder.

"Thought you might need this too, you don't want the little mite to starve." Mike held aloft the pink box of milk powder and stepped into the flat after John beckoned him in.

"Thank you so much Mike you're a life saver. Harry just abandoned her in the apartment with nothing but the set of clothes she was wearing, her car seat and travel bag. She looks like she's only 11 months old" John said over his shoulder as he went over to the kettle to make tea.

"No tea for me thanks" Mike glanced at his watch "promised the wife I would pick up the kids from school even though it's suppost to be my day off. And all this stuff was no bother; Graham is way too old for it anyway."

John walked back over to Mike and took the stuff off him only to dump it on the floor since all the tables were covered in a range of experiments such as severed fingers to test which substances cause them to rot fastest, tomato or BBQ sauce.

"Anyway good to see that this one hasn't scared you off like he did with so many other flat mates," Mike pointed at Sherlock who had either been ignoring him or too deep in thought to register another human beings presence. Knowing Sherlock it will be the former thought John. "Bye then, we ought to go out for drinks the three of us and my wife."

John promised he would although he was sure he saw Sherlock's left eyebrow twitch as if to say 'really John? Do you want me to waste my time in a pub having idle chit chat?' and followed Mike down the stairs to show him out of the building.

"You know Sherlock you could as least say hello when we have guests, we don't exactly have many and he was doing me a favour because..."
John was cut off because Sherlock had pinned him against the wall as soon as he walked back into the flat and was attacking John's lips as if it was his last day on earth. John reciprocated with as much force as Sherlock as his body had been aching because of their time apart.

"John, I have been on a case for the past 5 days." Sherlock panted when he finally broke the kiss. "Not having you there nearly killed me and now I am so randy it hurts."
