All of these are going to be pretty Sherlock and Rosie centric. Here we go:

Sherlock calls Rosie, my dear Watson, Watson, or sometimes he calls her his little Bee. I love the idea that Sherlock can never just call her by her actual name and just sticks with loving nicknames. Unless they're in a serious situation, then he brings out the Rosie or even Rosamund.

Uncle Mycroft only ever refers to her as Rosamund or child like he did in Indefinite Lines.

John sticks with Rosie

Rosie calls Sherlock, Sherlock. As others have said in the past, it makes no sense for her to randomly wake up calling him dad, as she would have been taught her entire life that he's Sherlock. Rosie would tell everyone that she has a daddy and a Sherlock.

Even when she's older and understands that both of them are in fact her dads, she never wants to call him dad. Not because she doesn't see him as her dad, but because it feels more special. Almost everyone has a dad, but she's the only person in the world who gets to have a Sherlock as well.

Sherlock becomes an expert on all things babies when Mary's pregnant. As described this post Sherlock is one of Rosie's main caregivers, along with Mary, John and Molly. Rosie is just so comfortable with him at a stage in her development when she should be developing a fear of strangers. Sherlock must have watched her a lot then for him to be one of her primary caregivers.

Sherlock researched everything from milestones to tummy time to the exact temperature the nursery should be kept at, everything.

He made sure that 221b was babyproofed whenever he was supposed to be watching her. Even if he was on a case, he would find himself distracted and preoccupied by the baby. He made sure to buy extra nappies so that he would never run out, Mycroft hated him for this (Sherlock never accepts money for his cases, so Mycroft allows him to use his money).

He unintentionally annoys John and Mary with his expertise. He corrects them on facts they get wrong about infant care. Even if his constant corrections and infodumps annoy them, they really don't mind that much. They are thrilled that Sherlock loves Rosie so much and that he cares enough to do extensive research that most parents wouldn't think of doing.

Little baby Watson is his whole world outside of crime solving. When Mary dies and John doesn't want to see him anymore, it breaks his heart that he may never see Rosie again.

Sherlock lulls baby Watson to sleep with his violin playing. Sometimes he lulls John to sleep too. Oopsie!

Sherlock unironically says oopsie all the time while helping raise Rosie. The Operation scene was one of my favorite parts of TEH.

Rosie has curly hair, like Mary did in season 4. John is so glad that he has a resident expert on curly hair. Sherlock ends up being the one to do her hair when she's little, and the one who teaches her to do it herself when she's older.

Rosie is Autistic just like Sherlock and John feels a little outnumbered, being the only Allistic in the household.

Jokingly of course. He's really supportive of them both.

During the pandemic, Sherlock has to take a break from being a consulting detective. Not being an official member of the team at Scotland Yard means it would be really dangerous to bring him in to help and clients he would get from the website are rightfully to scared to go to him.

John has to work even more hours than he used to at the surgery and Sherlock spends most of his days bored out of his mind. The only feature of interest to be found is his five year old daughter, who is also bored out of her mind.

In order to get them both out of their boredom, Sherlock decides to teach her. He buys her her own violin and teaches her to play the violin. He teaches her to dance (usually to Disney music, which starts to grow on him after the first hundred times they listen to For The First Time In Forever). He teaches her the science of deduction, how to observe like he does. Sherlock even teaches her to build her own Mind Palace.

Eventually, Sherlock decides why stop there? Why not teach her things she will learn in primary school so she can have a head start?

So he teaches her kindergarten level maths, he helps her improve her reading skills, he teaches her to write. In no time at all, she is way above the preschool level she would be at if she were still going to daycare (they pulled her out of daycare because they thought it would be safest to keep her home).

Months later, when she starts primary school, she is slightly ahead of her peers because of all of the things that Sherlock taught her out of pure boredom.

Contrary to most people's headcanons, I think that Sherlock would definitely not want Rosie to go anywhere near a crime scene. Yes, if it was absolutely necessary, if it were his only option, and if the crime scene is a "code green", then he'll bring her along. But he made a vow to protect her and he's not going to let two Watsons die under his watch. He also loves her more than almost anything else in the world, the other being John. Her loss would break his heart.

But like the first scene in Indefinite Lines, if a client were to show up at the flat and Sherlock was in the room with her, he would allow Rosie to practice her detective skills on clients.

If you haven't read Indefinite Lines and you're comfortable with Explicit fics, you should read it. It's awesome!

The weekend before Rosie starts primary school, Sherlock finds himself crying as he looks through her old baby things, because his little girl is growing up so fast. He's a sentimental mess for his family.

Sherlock gives up his dangerous/self-destructive vices when John and Rosie move into his flat. He makes sure the flat is completely drug free and goes to great lengths to ensure that he is able to give up for good. It's definitely not going to be easy, but it's worth it for Rosie. He doesn't even smoke regular cigarettes, opting once more for nicotine patches.

He buys a mini fridge for his bedroom to keep body parts in. He keeps his gun in another room so that he's never tempted to use it on the wall. He baby-proofs everything. He makes sure to teach Rosie how to be safe around his experiments and sometimes just doesn't do them when she's in the room. He puts them away when he's finished with them.

Rosie and Sherlock gang up against John sometimes. For example, Rosie has been begging for them to get her a dog and when John said no, Sherlock started begging right with her. They basically teamed up and annoyed John into allowing her to get a dog.

I can't come up with a good dog name at the moment that isn't Archie (listen to Sherlock & Co. if you haven't). But a hilarious idea would be Bluebell. It's so not a dog name, but can you imagine the absolute heart attack our favorite duo would have if Rosie suggested "Let's name him Bluebell!"

Yeah, John ended up being the one in charge of Bluebell more often than not, due to Rosie being four years old and Sherlock being extremely forgetful. But he loves Bluebell the dog and doesn't mind.

One of the only real arguments against parentlock that I agree with is that 221b is not a safe place to raise a child. Like, at all. Even with the baby proofing and Sherlock getting rid of all his dangerous habits, it's not safe. It's never going to be safe so long as it's Sherlock and John who are raising her.

Due to John's association with Sherlock, the only way Rosie would ever be safe would be is if he were to move to another country, change both of their names and wear sunglasses all the time in case of the off chance that someone recognizes him as John Watson. Both of the boys have made too many enemies for Rosie to be safe any place in the world.

I think that 221b is about as safe as any other place, so why not raise her there? She would be in danger either way.

As for Sherlock and John having a dangerous career which means they aren't guaranteed to come home each day, the only thing which makes their career different from parents who work in the police force or parents in the military is that Sherlock conducts most of his business in his own home. If a situation were to go south, it would not only put him and John in danger, but Rosie as well.

I feel like Uncle Mycroft would place an even higher security detail on 221b and Lestrade would be on speed dial in case something happened.

In the case of any dangerous happenings at 221b, I think John with his military training would be able to put it to good use in order to ensure that no one gets to Rosie. Sherlock is a skilled boxer and sword fighter, so he would also stand a chance against any bad guy who even thought for a second that they could go anywhere near her. Any bad guys who try to go near her would be skillfully taken down by her papa bears without a single thought.

Rosie would definitely be taught self defense strategies by both her daddies too. She could definitely hold her own in a fight, but she should also never have to.

I also think that in the case that a case is simply too dangerous, Sherlock would send John home. Rosie needs one parent alive in the event that something happens, it might as well be John.

Sherlock would try his best to pick cases that are unlikely to be too dangerous, but it's impossible to predict the way a case will turn out until it's too late. He would never go out of his way to pick a case that is likely to put himself or his family in danger, but it's impossible for him to tell how safe a case is at first glance.

I think they would just take their chances.

Maybe they would install a bedroom door for Rosie which is impossible to break down and locks from the inside? A metal door which would hurt the bad guy if they were to attempt to break it down. Rosie would be safe as long as she's in her room.

I guess problem solved!

Rosie grows up to be a forensic artist, combining her passion for crime solving and her passion for art. She works for Scotland Yard, which means that since she's a skilled amateur detective, on slow days she may get called in to help investigate.

When she was little she wanted to be a consulting detective just like Sherlock. Sherlock was and still is her hero, even though he tells her over and over that heroes do not exist and if they did he wouldn't be one of them. He is her hero.

In the spirit of her parents teaching her things they're experts on, John teaches her lots of medical stuff as well. Everything from basic first aid, to more advanced medical care you can provide at home, to of course, how to break every bone in someone's body while naming them.

He's also the one in charge of most of her self-defense training, teaching her things he learned in the military that a civilian could legally do in the case of an attack. He is careful to remind her that she should only use these moves in an emergency. When someone is really in danger.

Despite his usual lack of tact, Sherlock proves to be better at handling teenager problems than John.

When Rosie gets her period, Sherlock is able to deduce the exact kind of menstrual product she prefers and gets it for her each time. John tries his best, but he doesn't know the difference between brands and gets the wrong one each time he's sent.

When Rosie brings partners over, John is always completely oblivious to who they are, while Sherlock deduces that they're dating Rosie immediately when they enter the room. He can in fact tell if someone is a platonic friend or a romantic partner, and rarely gets it wrong. If he deduces that someone is Rosie's romantic partner, he gives them the threatening dad talk when she's out of the room.

It is said to be a good sign that someone is a keeper, if they can survive Sherlock's dad talk. Teens fear him even more than her Captain John Watson war hero father. It's very effective in weeding out the ones who are just simply not worth it.

Sherlock can be surprisingly patient and caring, but only when it comes to Rosie. When she's experiencing difficult emotions and needs to talk about them, Sherlock is all ears. He read somewhere on the internet during his early days with Rosie that it's important to give children a choice, "Do you want advice, or do you just want me to listen?" and Rosie picks listen about 99% of the time. So Sherlock listens. He tries his best to bite his tongue whenever he has something to say, it doesn't always work. But Rosie knows he tries and it means the world to her.

Of course if she does need someone to talk to about her emotions who will give her good advice, she goes to John. While they are both good listeners, John is better at both the listening and the advice.

In order to not make the same mistakes that their parents made, Sherlock and John both turn to the internet for advice. They try to use some elements of gentle parenting when parenting Rosie.

Sherlock basically memorizes the scripts of gentle parenting posts he reads on Pinterest in order to not be too much like himself when interacting with Rosie. He really doesn't want to get this wrong.

John grew up with emotionally abusive parents and he knows that if he doesn't do something, he'll end up repeating their behavior with Rosie. He also takes to memorizing what Pinterest has to say on dealing with various situations.

(I'm obsessed with parenting Pinterest and I'm only 19. I think there's something amusing about John and Sherlock being "Pinterest Dads")

John didn't even want children before he had Rosie. While it's perfectly valid to regret having children (as long as you try your best and make sure that they know they are loved), John doesn't regret having Rosie for a second.

As much as he was terrified of having a child, from the second he found out about Mary's pregnancy, he was filled was so much love for the baby, that he was willing to do anything to give her a good life.

Sherlock loves babies and had always wanted children of his own. But being aroace (well greyroace, because he does fall in love with John), mentally unhealthy, having a dangerous career, and being all around completely unsuited for potential fatherhood, he never thought it would be possible.

But as indifferent as he at first appeared to being named Rosie's godfather, it is his greatest privilege to be able to help look after her.

As an infant, Rosie had this onesie I found at Walmart (it only came in preemie size, so I couldn't add it to my hope chest :( but it's perfect for Rosie!)

Jawn onesie! It's perfect is it not?

I know we tend to go for bees when it comes to Rosie's wardrobe and I am obsessed with that too. But come on. She needs at least one hedgehog and one otter themed outfit, stuffed animal, something, okay?

Here is a link if anyone wants to buy this onesie :)

(to clarify, it only came in preemie size at the Walmart I was at, it does in fact come in other sizes online. I just don't need an infant onesie badly enough to justify ordering one online.

I simply buy them when I see them in the store and add them to my hope chest to ensure that my future children will have what they need in the event of a financial emergency)

That kinda got away from me! I saw this post a month ago when you first posted it and couldn't come up with anything.

Sorry for dumping all of these headcanons on you! But it was certainly fun to come up with all of them!

Sherlock post season 4!

Enough of serious discussion, I want the sweetest and most comforting headcanons of yours post s4. What do you think Sherlock, John and Rosie is doing? Pranking Mrs Hudson? Making fun of Mycroft? Molly taking care of Rosie while the boys are out with lestrade? Rosie cuddling to Sherlock to sleep every night instead of his father? Come on feel me in.
