25-year old Lauren Jauregui watched as her year 13 students left her classroom, backpacks swung over their shoulders as they chattered excitedly to one another. It was 4 O clock, which meant she had just half an hour until she was supposed to be at the house of the girl she was going to be babysitting after school for the next two weeks while her parents were out of town. Well, technically today was just a trial after which Lauren would decide whether or not she could do the full two weeks, but she couldn't see herself saying no. How hard could babysitting a 15-year-old be?

Lauren had just moved to Chicago and so was new to the school, however, when she heard that they had a program where teachers could sign up to babysit children in the younger years of the school, she had immediately decided to take part, both because she loved children and wanted to earn some extra money. She had been surprised to find that she had been paired with a 15-year-old rather than, say, an 8-year-old, but the job certainly paid well so she wasn't complaining.

The dark-haired girl quickly slid her laptop into her handbag before lifting it onto her shoulder and then walking out of her classroom, turning off the lights as she left. She opted to stop at Starbucks on the way to pick up an iced latte, knowing she would need the power boost, before walking the fifteen minutes it took to get the large house she would be babysitting at.

"Hi, you must be Lauren!" A blonde lady said warmly, opening the door. 

"Yes," Lauren smiled.

"Please, come in," she said, quickly stepping back. Lauren was immediately greeted by the sound of loud sobs coming from the living room. "Uh, Camila's not very happy that she has to have a babysitter," the lady explained, leading Lauren to the kitchen. "I'm Serena, by the way," she introduced herself.

"Are you Camila's mum?" Lauren asked.

"Yes," Serena replied after a moment's hesitation. "Technically, she's adopted, but she doesn't know so that stays on the down-low."

"Got it," Lauren nodded, taking a seat at one of the chairs at the kitchen island.

"She's really lovely once you get to know her," Serena said, although she didn't seem all too convinced herself. "Uh, she's got ADHD so she can be a bit fidgety and impatient but it shouldn't be too much of a problem if she takes her meds, you need to give them to her at bedtime and breakfast."Lauren nodded as Serena waved a bottle of pills in the air before placing it back down on the counter.

"She'd kill me for telling you this, but she has accidents so she needs to wear pull-ups, you need to change her in the morning, after school and before bed, she won't tell you when she's wet so you have to keep checking and she often tries to get away with not wearing one, don't let her," Serena continued.

"So they are for bed-wetting and also during the day and to school?" Lauren asked. Although she was slightly surprised to hear this, she knew that ADHD often led to children being unable to control such things.

"Yes," Serena nodded. "She's a picky eater but I'm sure you'll manage, uh, she gets distracted and needs prompting to continue tasks at times and help to get changed in and out of her school uniform and having a bath because she's not great at washing her hair and body, if all goes well you'll be staying in the spare room on the second floor, Camila's room is on the third, we still have crib bars on her bed becuase if we don't she'll never go to sleep, and that's about all you need to know."

"Bedtime?" Lauren asked with a raised eyebrow as Serena grabbed her purse.

"Uh, 10," the lady shrugged, before leading Lauren into the living room where she was met by the sight of a girl in her school uniform in tears on the floor while a man, who she assumed was her adoptive dad, was bent down trying to reason with her. She immediately recognised the girl as being one of the year 10s she had gotten into trouble a few days ago for running in the corridor. The child she was now looking at was nothing like the sassy, outspoken mean girl Lauren had encountered at school and looked more like a toddler throwing a tantrum.

"Look, Camila," he tried upon taking notice of Lauren. "She looks like a perfectly nice lady."

"I'm way too old to need a babysitter!" Camila shouted, tears still streaking down her face. "And I can't believe you got a teacher from school, that's so embarrassing," she groaned.

"Camila, why don't you say bye to your parents?" Lauren suggested, nodding at both of them to let her know that she could handle the situation.

"Alright, we're going darling, see you tonight," the man said, standing up.

Serena pressed a quick kiss on the girl's forehead and only moments later the sound of the front door closing echoed through the house.

"I'm not a baby, I don't need a nanny," Camila muttered, wiping her tears and crossing her legs.

"Of course not," Lauren nodded. "Why don't you go change out of your school uniform and then we can do something fun?"

"NO!" Camila shouted angrily, slamming her hand down onto the carpeted floor.

"Sorry, love," Lauren said, suddenly realising she was forgetting what Serena had just told her. "Come on, I'll help you," she said, offering Camila a hand.

"I don't need help getting changed," Camila insisted.

"Alright," Lauren sighed, putting her hands up. "Go get changed on your own then, but if you need any help you can come find me," Lauren said.

"Fine, but I won't need any," Camila rolled her eyes before getting to her feet and running up the stairs.

Lauren shook her head, slightly amused, before going to find the room she was supposed to be staying in.

It was half an hour later when she decided it was time to go check on Camila. She jogged up the carpeted stairs to the very top of the house where Camila's room was, sighing sympathetically when she saw Camila sitting on her bedroom floor, huffing in frustration as she tugged violently at the buttons of her shirt as if she thought they would magically undo themselves. She had managed to pull down her tights but not take them off due to the buckle on her school shoes but that was about it.

"I told you to come and find me if you needed help," Lauren said, watching as Camila's head snapped up upon hearing her voice.

"Go away, I'm fine," Camila mumbled.

"How about I undo the buttons and your tie and shoes, and you do the rest?" Lauren suggested.

"No!" Camila shouted angrily.

"Look, you need some help, sweets," Lauren said, deciding it was time to be the adult and put her foot down. 

"GO AWAY!" Camila shouted as Lauren walked into her room, silently taking note of the pink walls and abundance of teddies. 

Lauren ignored her, bending down and starting to undo the buckles on Camila's shoes.

"GET OFF!" Camila screamed, kicking her legs.

"Excuse me, don't kick me," Lauren scolded firmly.

Camila didn't reply, instead continuing to kick her legs.

"Camila, hey, listen to me," Lauren snapped, grabbing Camila's legs and holding them down firmly. "You are going to sit still for me, okay?"

Camila whimpered slightly at Lauren's strict tone, but all the same obeyed and stopped kicking, sticking her thumb in her mouth to soothe the embarrassment of needing help.

"Look, we're gonna do this together, okay?" Lauren said, her tone softening slightly. She took off Camila's shoes and tights before moving to take off her tie unbutton her shirt. "Take this off," she said, tugging at Camila's shirt, deciding it would help to make it seem like Camila was doing some of it on her own. She immediately noticed that the girl's chest was budding slightly and looked red and sore, indicated she should be wearing a training bra, at the very least, but decided it wasn't the best time to mention it. "You're doing really well," she praised, unzipping Camila's skirt and letting her step out of it herself.

"I want to wear this," Camila said around her thumb, walking over to her cupboard and pulling out a pair of sweatpants and an oversized jumper.

"Okay, but first things first, where's your changing mat, doll?" Lauren asked, knowing this wasn't going to go down well.

"I want to wear this," Camila repeated, thrusting the clothes towards Lauren.

"I know, but I think we need to take care of this first," Lauren said gently, tapping the band of the pull-up on Camila's waist. 

"No, I'm fine," Camila insisted.

"Look, I know this is hard," Lauren said, eying the obviously wet pull-up, "but the longer we argue about this the harder it'll be, so let's change you into a fresh pull-up, and then we can forget about it."

"I'm not a baby," she said, her voice breaking as she did so.

"I know," Lauren said softly. "I know you're not a baby, but big girls can have accidents too, you know."

"They can?" Camila asked tentatively.

"Of course!" Lauren exclaimed, relieved Camila was listening to her. "And big girls like you can wear pull-ups too, no big deal! Now, where's your mat?"

"Here," Camila said, grabbing a plastic pink changing mat from under her bed. 

"Is this your diaper bag?" Lauren asked, nodding towards a velvet pink bag sitting on the floor. "Okay, sweetheart, lie down and I'll do this as quickly as possible," she promised, grabbing the bag.

"Can I have a snack?" Camila asked as she sat down on the mat.

"I think it's almost dinner time, we can go see what there is after this," Lauren said, pushing Camila's shoulder's back so she was lying down and then starting to undo the tape at the sides. "Do you know what you'd like to eat?" Lauren asked, trying to distract Camila as she removed the wet pull-up and started wiping down her privates.

"Frosting," Camila replied.

"We're not eating frosting for dinner," Lauren laughed. "Do you want to help me put this on you?" she asked, holding up the fresh pull-up. Camila nodded eagerly, standing up. Lauren helped her by holding it the right way around while she stepped into it and then let the younger girl pull it up on her own.

"Why not frosting?" Camila asked.

"Because it's pure sugar and it's not substantial enough," Lauren explained, helping Camila into the clothes she had chosen.

"But it's what I like," Camila shrugged.

"I'm sure there are other things you also like," Lauren reassured her. "Come on, let's go see what we can find," she said, ushering Camila out of her room. She watched as the younger girl sprinted down the stairs energetically, following behind at a much slower pace.

"Do you want a small snack?" Lauren offered as Camila jumped around the kitchen island in circles.

"I want chocolate milk," Camila said, pointing at the fridge.

"Okay," Lauren said, opening the fridge and finding a carton of chocolate almond milk on the top shelf.

"NO!" Camila screeched, immediately bursting into tears as Lauren started pouring it into a glass.

"Hey, I thought you wanted chocolate milk?" Lauren asked in confusion.

"Hot in my cup, hot in my cup," Camila echoed.

"I'm sorry, I didn't know that you have a special cup or that you like your milk warm, but now that I do we can fix that, can't we?" Lauren said. Camila hesitated for a moment before realising that Lauren was right and nodding. "Right, now, where is your special cup?"

"Here," Camila said, picking up a pastel yellow sippy cup with a faded bumblebee on the front. 

"How about pasta for dinner?" Lauren asked, resisting the urge to coo at the babyish cup.

"Frosting," Camila said adamantly.

"How about pasta for dinner and we make cupcakes for dessert?" Lauren compromised as she popped the sippy cup in the microwave.

"Cupcakes with frosting?"

"Yes, Camz," Lauren laughed, letting the affectionate name slip out.

"Okay," Camila agreed.

"Do you want to get started on your homework while I make dinner?" Lauren asked, opening the cupboard.

Camila didn't reply, taking a sip of her milk.

"Camila, come here," Lauren said, picking up the girl's backpack and unzipping in, pulling out the academic planner that she knew the school used for the year 10 and 11 students.

"Why?" Camila asked, walking over and climbing onto the seat.

"You have Maths and English, which one do you want to do first?" Lauren asked.

"Maths," Camila decided, watching as Lauren opened her workbook up for her.

"Start on this," Lauren said, pointing to a series of questions before leaving Camila to get on with it while starting to boil the pasta.

It was only three minutes later when Camila lost all concentration, opting to climb onto the island instead of attempting the problems.

"Hey, get down," Lauren sighed when she turned around, quickly lifting Camila back onto her seat.

"But I'm bored," Camila whined.

"Okay, come 'ere," Lauren said taking Camila's hand and leading her to the pantry. "Which is your favourite?" she asked, showing the girl the bags of sweets.

"This one," Camila said, pointing to the Percy pigs hopefully.

"Percy Pigs it is," Lauren said, grabbing a handful and putting them in a bowl. "Okay, you can have one sweet for every five minutes of homework," Lauren explained. 

She normally used this trick on younger children, but an hour later wen Camila had finished all of her homework, her suspicions that it would work on her too were confirmed.

"I'm done!" Camila exclaimed excitedly, reaching over to grab the last sweet.

"Awesome, great job," Lauren praised. "Do you have any notes in your diary?" she asked, knowing that at school the teachers often wrote notes for parents that needed to be signed. "Your mum and dad aren't here so I can sign it for you."

"No," Camila muttered, obviously lying.

"Okay, why don't you get me your diary anyway?" Lauren said knowingly. "And we can have dinner after that."

"Fine," Camila rolled her eyes, grabbing the small book from her backpack and handing it to Lauren before scampering off.

The older girl opened the book tentatively, knowing that Camila was likely embarrassed by whatever the note was which was why she had left in such a hurry.

Dear Mrs. Smith,

Unfortunately, Camila not letting the nurse change her pull-up at lunch is still an issue. We are unsure of how to tackle it at this point as we have tried all possible alternatives. We understand that this is a sensitive topic for her, however it is crucial that we find an effective solution soon. Please be in touch.

Kind regards,

Miss Epseley

Lauren sighed, quickly signing the book before closing it. She knew that Miss Epseley was one of the undergraduate students working as a teaching assistant at the school and assumed that she was working as Camila's teaching aid that year. It was clear to the older girl that Camila was having a hard time.

"Camila, dinner!" Lauren called.

"Don't like pasta," Camila commented as she caught sight of what Lauren was dishing up.

"You haven't even tried it yet," Lauren bargained.

"I want my plate and my fork," Camila whined as she pushed her thumb into her mouth, frustrated that Lauren wasn't doing it right.

Lauren raised an eyebrow at Camila's childish behaviour but, all the same, went to look for 'her' plate in the cupboard. She was slightly annoyed that Serena hadn't mentioned many of Camila's requirements to her in the begining, but she was coming to realise that the girl wasn't very well looked after for the most part.

"This one?" Lauren guessed, pulling out a sectioned plate with Winnie the Pooh illustrations on it. Camila nodded, moving ot the cutlery draw to pull out a matching fork.

"I want my spaghetti plain," Camila instructed.

"Okay, but you need to have some carrots too," Lauren said, neatly spooning the food into the different sections of the plate. "And can you please take your thumb out of your mouth so you can eat some dinner?"

"I don't suck my thumb," Camila snapped, quickly pulling her hand away from her mouth.

"Thank you," Lauren said, putting Camila's plate in front of her before making her own.

"I'm tired," Camila complained, resting her head on the table.

"It's been a long day for you," Lauren said sympathetically, watching as Camila made a tower out of her carrot slices. "After dinner let get you in a bath and then pyjamas so you're ready for bed by teh time your parents come home."

"I don't need a bath," Camila shrugged.

"Hmm, that's not what your mum told me," Lauren said. "Do you want to talk about what Miss Epseley wrote in your school diary?"

"No," Camila mumbled.

"Do you not want to think about a solution?" Lauren asked. "It can't be comfortable to sit in a wet pull-up through all your afternoon classes."

"I don't wanna talk about it," Camila said quietly.

"Alright, but when you are ready, we can start brainstorming together," Lauren said, giving Camila a small smile.

"It's just so embarrassing," Camila sighed, resting her chin her her palms. "I hate it, there are always other kids there and Charlie is so obvious about it."

"That sounds really hard," Lauren nodded, taking a bite of her food. "What do you think would make it easier?"

"Not having to be changed," Camila muttered.

"Okay, so we need to get you potty-trained, we can do that if that's what you want," Lauren said, watching Camila closely to gage her reaction.

"I don't know how to," Camila said, pulling her knees up to her chest.

"That's okay, I can potty-train you, I've done it with loads of kids," Lauren said, trying to not make it a big deal. "But love, you need to make sure you're ready for this, it's a big step."

"Of course I'm ready, I'm fifteen," Camila shrugged. 

"Okay, but it won't happen overnight, so what do we do in the meantime?" Lauren said, tapping Camila's plate to prompt her to continue eating.

"I'll change when I get home," Camila said, wanting the conversation to end. 

"If you'd feel better about it, you can come to my classroom at lunchtime and I can change you there instead of the nurse doing it," Lauren suggested.

"Don't you teach year 13?" Camila asked dubiously.

"Yes, but believe it or not most of them don't like spending lunch time with their teachers," Lauren joked. "Who's your class teacher? I'll pop by to talk to her tomorrow."

"Mrs. Williams," Camila said, picking up a piece of spaghetti and dangling it above her mouth.

"Okay, poppet, can you some more of your pasta please?" she asked as Camila pushed her half-full plate away.

"No," Camila whined, resting her head on the table. 

"Okay, okay," Lauren gave in, standing up and taking Camila's plate. "Should we go and sort out your bath?" she asked, offering Camila a hand.

"I don't want a bath," Camila complained, tears clouding her eyes.

"Hey, it's okay," Lauren soothed. "Let's just get it over with and then we can watch a movie," thte older girl said, smiling when Camila finally accepted her hand. "What do you want to watch?" Lauren asked as she led Camila upstairs and started to run a bath.

"Can we watch 50 shades of grey?" Camila asked hopefully.

"Absolutely not," Lauren laughed.

"I want to be grown up," Camila pouted.

"I think you're just a bit too young for that one," Lauren commented.

"Fine," Camila rolled her eyes.

"We could watch frozen," Lauren suggested.

"I'm not five," Camila snapped sharply.

"Alright, arms up, Missy," she said, helping Camila out of her hoodie.

"Can we watch Sofia the First?" Camila asked.

"Of course we can," Lauren agreed. "Love, I could have changed you before dinner if you ahd asked," Lauren sighed, taking note of Camila's swollen pull-up.

"Can I have more chocolate milk when we watch?" Camila quesioned.

"Maybe just regular milk," Lauren suggested.

"No, chocolate milk," Camila corrected.

"You've already had chocolate milk though, haven't you?" Lauren said, trying to lay Camila down on the changing mat.

"Chocolate milk," Camila whined, stamping her foot.

"Excuse me, we are not going to have a tantrum over this," Lauren said strictly. "If you're hungry you can eat the rest of your dinner which you really should have done in the first place, but you're not having anymore chocolate milk tonight, am I clear?"

Camila sobbed audibly, dropping to her bottom in tears and curling up.

"P-p-please," Camila choked out.

"Doll, I know you're tired, but I can't give you more chocolate milk," Lauren explained gently.

"Lola always gives me chocolate milk," Camila insisted.

"And I'm not Lola," Laurens said, knowing Camila was referring to her usual babysitter..

"So does Mummy."

"And I'm not Mummy," Lauren replied. "Now, can we get you into the bath?"

"Okay," Camila mumbled, lying down so that Lauren could take off her pull-up. 

"There we go," Lauren said once Camila was fully naked. "Bath now, hmm?"

"Okay," Camila said, standing up. "Don't stare at me," she mumbled, climbing into the bathtub. 

"I'm not," Lauren promised, sitting down on the toilet lid. "But I do need to help you with the soap, don't I?"

"I still want my chocolate milk and if you don't give it to me I'm going to get it myself," Camila said angrily.

"Does Lola normally ust give you chocolate milk everytime you're upset?" Lauren asked, furrowing her eyebrows.

"I'm allowed as much as I want, she even lets me have it for dinner," Camila said smugly, dipping her head back to wet her hair.

"It's your choice as much as it is mine, Camila, whether or not I tell your parents that I'm willing to babysit you for the next two weeks, but we're going to be doing it my way and that means you can't live off of chocolate milk."

"Okay," Camila said quietly. 

"Right, let's get this knotty hair all nice and clean," Lauren said, moving to sit on the edge of hte bathtub and reaching for the 2 in 1 kids shampoo. 

"Don't like it," Camila complained, sticking her thumb in her mouth.

"I know, I'm almost done," Lauren promised, massaging the liquid into Camila's hair.

"When is Mummy coming home?" Camila asked.

"Soon, maybe in an hour or so," Lauren said, starting to pour water onto Camila's head. "Are you gonna show me how good you are at using the soap?" Lauren asked, squeezing some shower gel into Camila's hand.

"Yes," Camila said confidently, moving her hand to her legs.

"Good job," Lauren said, despite the fact that she had dropped most of the soap into the water. "Can I help you with the rest?"

Camila nodded, trying not to squirm at the feeling of Lauren's hands running over her skin.

"Out," Camila said agitatedly, slamming her hands into the water.

"Sweetheart, you're doing so well," Lauren praised as she finsihed rinsing off the soap. "Look at that, all done," she said, holding out Camila's towel for her and wrapping her up in it.

"All done," Camila echoed. 

"Do you have diapers for the night time, love?" Lauren ased as she led Camila into her room.

"No, I'm not a baby," Camila said in an annoyed tone.

"I was just checking, doll," Lauren reassured her. "Should we get you into a pull-up then?"

"No, just pyjamas," Camila insisted, reaching for her fluffy onesie.

"I think it's safer to wear some protection, don't you?" Lauren said gently.

"I'm big, I don't need them," Camila whined. 

"You've been doing so well, Camila, can we keep that going?" Lauren encouraged, picking up a fresh pull-up.

"I don't wet the bed!" Camila shouted, pushing Lauren away.

"Camila, if you want to watch Sofia the First then you need to let me put this on you, and if you aren't going to wear it then we won't be watching anything and I'll bring your milk up here for you to have on your own," Lauren said firmly.

"See if I care," Camila retorted, crossing her arms.

"Camila, I'm counting to three," Lauren said. "One...Two..."

"SHUT UP!" Camila screamed, bursting into tears.

"Right, come here," Lauren said, moving closer to Camila.

"W-w-want my choco milk," Camila sobbed.

"We've already talked about that, can you please let me put your pull-up on now?" Lauren sighed, suddenly realised how exhausted she was from spending the afternoon with Camila. "We can start potty-training tomorrow, and then we won't have this problem anymore, will we?"

Camila's sobs died down at this and she looked up at Lauren.

"Alright, let's go watch Sofia," Lauren said softly, moving forward and working the pull-up onto Camila hips. "This looks so comfy," Lauren continued the conversation as she changed Camila into her onesie.

"I want my milk," Camila said, standing up and taking the older girl's hand instinctively.

"Okay, I'll make you some milk in your bottle," Lauren said calmly. "Do you want to go wait for my in the living room?"

"NO," Camila shouted, looking close to tears all over again.

"Okay, okay, you can come help me with the milk," Lauren quickly said, giving Camila's hand a squeeze. 

"Lauren, look!" Camila exclaimed, trying to get the older gilr's attention.

Lauren looked around to see younger girl having climbed up onto the kitchen island.

"Down we get," Lauren said, reaching up and lifting Camila down.

"Bounce, bounce, bounce!" Camila shouted excitedly, jumping up and down excitedly.

"Okay, bouncing bean, should we start winding down?" Lauren asked, taking Camila's bumblebee sippycup out of the microwave.

"Sofia," Camila said excitedly, running to the living room and dropping to the carpet, scrambling around a little bit before finally settling down.

Lauren turned on the TV show before turning on her phone and starting to scroll through her social media, watching Camila out of the corner of her eye.

"Ouch," Camila mumbled.

"You okay, love?" Lauren asked, looking up from her phone.

"I want to go play outside," Camila said, standing up.

"Uh-uh, it's not play time," Lauren said, also standing up. "Finish your milk."

"No," Camila mumbled.

"Let's go up to bed, hmm?" Lauren suggested, not wanting the situation to escalate. It was already quarter to ten anyway.

"Okay," Camila agreed.

"I just need to grab your meds, lovely," Lauren said, jogging to the kitchen and tipping one of the round blue pills into her palm.

"Yuck," Camila pulled a face, pushing Lauren's hand away.

"We've got to do this, babe," Lauren sighed as she led Camila upstairs.

"I don't have it till I'm in bed," Camila said.

"Mm, okay, you can have it with your milk," Lauren said. "Up you get," she said, lifting Camila over the crib bars. "Here," she said, handing Camila the tablet.

"Can you come back tomorrow?" Camila asked sleepily as Lauren tucked her in.

"Of course," Lauren said gently, turning on the night light before turning off the main lights.

"Where's my milk?" Camila asked, sitting up.

"Right here," Lauren said in a soothing tone, handing Camila the sippycup.

"Most babysitters don't want to come back," Camila said as she lay back down and started sucking lazily on the mouth of her cup.

"Why not?" Lauren asked, furrowing her eyebrows.

"Because I'm naughty," Camila shrugged.

"But you don't mean to be," Lauren said, stroking Camila's arm in an attempt to make her feel sleepy. "Some kids just have a few challenges but that's okay," she continued.

"Okay," Camila mumbled in a tired manner, her eyelids growing heavy.

"Get some sleep, nena, I'll be back tomorrow," Lauren whispered, waiting for Camila's breathing to become steady, indicating she was asleep, before leaving the room.

This, she thought to herslef, is going tobe a challenge.
