Trying to start writing in standard format so let's clarify something real fast
Words with quotes means a character is talking.
But the "()" mean a character is thinking to themselves
-------------------------------------------
(The Hokage Mansion)
Minato and his wife Kushina was preparing for a small meeting with the head of the Hyūga clan Hiashi to talk about the affairs of Kumoakure.The Land of Lightning and the sacrifice of Hizashi Hyūga.
.......
"Are you ready for this minato?"
Kushina asked knowing that these meetings are always a bit morbid.
Minato sighed heavily, he didn't enjoy this meaning the sacrifice may have prevented a war, but it has different meaning to different people to himself he lost a friend,to the village they lost a shinobi, but to Hiashi it is something greater he had lost a brother, his family, and to someone else they lost a father.
.......
"Yes kushina I'm fine, just a little worried that's all."
Minato said as he sat on his chair.
"I know that tensions may be heating up between us and Kumo but we can avoid a war."
Kushina said
Unbeknownst to the two adults Naruto who was inside his playpen with Kurama was listening to the conversation.
"A war with the land of lightning but isn't that where Bee is?"
Naruto said to kurama with their shared telepathy
"Yes it is, but there is no telling what the conflict is about, but these affairs is something we should not be worried about."
Kurama said.
Naruto got a little worried, he didn't want anyone to go to war all of his friends the ones he worked so hard to make would more likely get hurt or worse die because of this war
"Ahh ahh!!"
"Huh?"
Minato turned around and he looked at naruto.
"I think he's trying to say something minato."
Kushina said as she walked towards the playpen and picked up the child.
"Come on sweetie you can do it."
Kushina said as she gentely bounced her child to coax him into speaking.
"Nnnn(Why am I having a hard time talking)?"
Naruto thought to himself as he was trying to speak.
"Come on Naruto you can do this daddy believes in you!!!"
Minato shouted excitedly
(The front door opened)
"Nnnnnnooooo Fiiii!!"
Naruto said loudly.
........
"Minato did your child just said no fight?"
Hiashi asked.
......
"You know what...he did...me and kushina was talking about the meeting and I think he knows what's going on."
Minato said as he picked up son.
"(I think they understood me)"
Naruto thought to Kurama.
"I think they did"
Kurama replied surprised his jinchuriki's plan had worked.
.......
"Hiashi my old friend thanks to my child I have gained a new resolve, we should try to make peace with the kumogakure, they're getting a new kage soon so we can try to improve relations there."
"Hizashi always did wanted to defy the odds...so be it we can discuss it during today's meeting."
"Good that settles it a peace treaty sounds wonderful?"
Minato asked.
"That means we can raise our children in a better world, if this falls through."
Kushina said happily.
"We can only hope."
Hiashi said.
"Speaking of which where is your family at?"
Kushina asked.
Oh Hinata and Hanabi had to take Neji back home to change him....he had an accident on the way here.
Hiashi said as he gentely laughed.
(Wait..what!!!)
Naruto thought to himself.
"Two year olds am I right"
Minato said patting his friends back.
"(WHAT!!)"
Naruto was shocked at the news he had just heard.
(Knock Knock)
There was a knock heard from the door.
"I'll get it, you two continue to talk."
Kushina opened the door to see a eighteen year old Hinata with a thirteen year old Hanabi, who of which is holding a small two year old Neji.
Sorry that it took us a little while to get here father, neji was a little upset.
Hinata timidly said as she bowed.
"Hinata you're too nice ,neji wasn't upset he started running through the compound naked, after we took him out of his clothes."
Hiashi looked down upon neji, giving the toddler a stern look.
"Is this true neji"
Hiashi asked his nephew even though he knew the truth.
.......
"Well neji I'm waiting"
Neji looked down at his feet as he began shuffling them refusing to look his uncle in the eyes.
"See father he knows he did something wrong."
Hanabi said.
"(That's neji he seems so different)"
Naruto thought to himself
"Neji if you don't tell me you're getting a spanking"
Hiashi said his usual empty threat not having it in him to spank his nephew.
Neji eyes went wide he didn't want to get spanked.
"Me do id untle."
Neji said hoping he wouldn't get a spanking.
"Now was that hard?"
Hiashi asked.
"No".
Neji said quietly.
"Good."
Hiashi sat down on the couch across from minato.
"Come here neji"
Hinata motioned for the toddler to come to her, neji ran into hinata's arms burying his head into the older hyūga's chest as he started blushing.
"Aww is someone a little embarrassed"
Kushina cooed at nejj.
"Neji doesn't really like being the center of attention."
Hinata said as she rubbed the child's head.
"Hinata you spoil him, you know that."
Hanabi said as she giggled.
"Hinata."
Hiashi called out to his eldest daughter.
"Yes father"
Hinata walked to her father.
"Why don't you take the children to the park for awhile, so they don't be cramped in here all day."
"We go da pawk mommy!"
Neji said excitedly.
"Yes we're going to the park"
Hinata smiled.
"You shouldn't let him call you that , might cause some confusion later on in his life."
Hanabi said.
"I don't mind that he calls me that, besides he has nobody else to call mother."
Hinata said as she sympathetically looked at the child.
"(Okay so now I'm confused)"
Naruto thought to kurama.
"(What are you confused about?)"
Kurama asked naruto.
"(So neji is a kid along with me,you,sasuke,and obito.)"
Naruto thought to kurama.
"(Correct)".
Kurama said.
"(So I think this whole thing has to do with the war right?)"
Naruto thought.
"(And I know it's not the infinite tsukuyomi, if it was that the moon would have the sharigan projected on it.)"
"(So what is it)"
Naruto asked
"(I dunno but it seems to be that we're the only ones who remembers everything)"
Kurama responded.
Naruto's and Kurama's telepathy was cut short when hinata picked up naruto and placed him in a stroller.
"You can come too naruto"
Hinata said as she buckled naruto into his stroller.
"Rama rama!!"
Naruto reached out to Kurama.
"I know naruto"
Hinata pulled out a leash from Naruto's stroller and she clipped it onto Kurama's collar.
"You should come with us, it's a nice day outside"
Hinata said as she gentely picked the fox up and placed him on the floor outside the playpen.
"(So soft)"
Kurama thought to himself that this woman has such a motherly aura around her.
"Okay you guys be careful okay"
Kushina said as she sat down beside minato.
"We will."
Hinata bowed and turned towards the door, but before she left she saw her little sister with a disappointed look on her face.
"Would you like to help me hanabi I could use the help"
Said Hinata not wanting to leave her sister out of the small trip.
"I mean if you absolutely need my help...yes."
The younger sister said as she slipped her shoes back on.
Hinata bowed to minato.
"Thank you for inviting us too your home"
"You don't have to be all formal, and no problem."
Minato said with his trademark smile.
Hinata pushed the stroller outside and she had Hanabi pick up their younger cousin and they exited the mansion.
.....
"She reminds me of my wife so much."
Hiashi said.
"Yeah Hinata does seem like a natural mother."
Kushina said her mind now in ease that knowing her child is in good hands.
(The Park)
Hinata and her small group had finally made it to the park, there other families at the park enjoying the nice weather and overall having a pretty good time.
"Mommy mommy ou puh me on swing"
Neji asked his cousin and mother figure.
Hinata knelled down to neji's height.
"Sorry Neji I can't, I have to watch the baby, but I bet if you ask cousin Hanabi she could push you on the swing."
Neji looked at his other cousin, it's not that he doesn't liked her, but he didn't feel the same way about her as he does for hinata.
"Wan mommy puh me."
Neji replied.
"Neji I have to watch the baby but you can go play with hanabi."
Hinata said.
"Come on neji it'll be fun."
Hanabi said as she picked up the toddler.
"No no no no no!!"
Neji started throwing a tantrum.
"Oh there he goes."
Hanabi said as she put the child back down.
Hinata sighed she didn't know why her baby cousin was so irrational.
While the whole scene was playing out Naruto couldn't help but to looked surprised.
"(This is neji)!?"
Naruto thought to Kurama.
"I remember him being a bit more calm,cool,and collected."
Kurama responded to his jinchuriki.
Hinata knelled down to the raging toddler.
"Neji I know you want me to play with you but I'm busy I have to take care of naruto."
Neji began crying.
"Nod fa, me hewe fiwst"
Hanabi giggled.
"Did he just say he was here first."
Hinata sighed
"Hanabi don't laugh, neji is upset."
"(Wow he's a clingy kid)."
Naruto said.
"(You're one to talk mister what if they die again)."
Kurama said recalling the time naruto had to be babysat by Sakura.
"(Shut up!!)"
Naruto said to kurama, the fox mischievously giggled.
Neji continued his tantrum trying to get the attention of his mother figure.
Hinata sighed she wanted to comfort the child but she knew she had to let him work this out on his own.
"Mommy pway wi me nod baby!!
Neji screamed the toddler had himself sprawled on the ground, kicking his feet to emphasize how displeased he was.
"I don't think I ever saw him this bad before."
Hanabi as she watched the scene unfold in front of her.
"He has to work this out on his own, it's hard for me to see him like this but he needs to."
"True to her word Hinata let her cousin throw his tantrum, the toddler had tried everything to get a reaction from hinata but she didn't budge so neji sat on the ground his tantrum leaving him exhausted.
"Are you done neji"
Hinata asked.
Neji nodded.
"Good now can you use your words, instead of throwing a tantrum."
Hinata asked neji.

.......
"Yes"
Neji replied.
"Good."
Hinata said as she picked up nejj and placed him on her lap.
"Neji you know mommy is taking care of a baby right."
Neji nodded.
"And you know naruto is a lot younger than you right neji"
Hinata asked the toddler who of which nodded in agreement.
"So you should know that naruto can't take care of himself like you can."
........
"Yeah"
Neji said as he started to look down to his feet.
Hinata gentely lifted neji's head up.
"I'm not mad neji but you shouldn't be throwing tantrums just cause something is not going your way understand."
Neji nodded.
"(I never knew hinata was like this)"
Naruto said a little surprised at hinata's actions.
"She's like a mother even though she doesn't have any kids of her own."
Kurama said as he jumped onto the bench.
"Wow hinata you handled that pretty well."
Hanabi applauded her older sister.
"That's how I use to do when you were younger."
Hinata said as she softly chuckled.
"Whatever."
Hinabi said as she sat on the bench.
....
"Hey neji do you want to see the baby?"
Hinata asked.
Neji nodded.
Hinata pulled naruto out of the stroller and she sat him on her other knee.
"He baby?"
Neji asked.
"Yes you see how small he is that means he a little bit more sensitive than"
Hinata said.
Kurama started laughing.
"(I am not sensitive)"
Naruto said.
Neji touched naruto's cheek.
"Dob."
Said naruto as he tried to push neji's hand away.
"Baby mean!"
Neji pouted. It
"(I'm mean, you're the one who threw a fit just a seconds ago!!) Responded naruto. 
"Neji I don't think naruto likes having hands in his face"
Hinata said as she gentely moved neji's hand.
"Why don't you just humor the kid naruto and you know just be a baby."
Kurama suggested to his jinchuriki.
..........
("You know what....why not.").
Naruto tugged on hinata's shirt.
"Yes naruto."
Hinata down at the child that was on her lap.
"Pway."
Naruto says as pointing to the play area of the playground.
Hinata had a idea where both neji and naruto could have fun.
"Neji do you want to help naruto build a sandcastle."
Neji turned his head away from naruto.
"Baby meanie"
Hanabi sighed
"He sure is stubborn hinata."
"Baby don wan pway wi me cuz he meanie."
Neji said as he pouted.
Hinata placed both neji and naruto in the sandbox.
"Now neji you love building sandcastles with mommy right?"
Hinata asked neji.
The toddler nodded.
"Then me and you can build a sand castle only if you let naruto play."
Hinata said hoping neji would agree.
Neji made a extended groan but he accepted the offer.
"Otay."
"Good now do you remember how we start"
Hinata said.
......
"We ged a wot of sand."
Neji said as he began to pile a bunch of sand up so he could begin building the sandcastle.
"(Hey this looks kinda fun)"
Naruto thought to himself as he begins to pile the sand together he had then made his sand pile into a castle.
Hinata looked at naruto's sandcastle and she was amazed.
"Naruto you did that all by yourself?"
Hanabi was in disbelief.
"That is one smart baby."
Hanabi said.
Hinata rubbed naruto's head.
"He is the Hokage's child"
Neji started feeling immensely jealous that naruto was taking all the attention away from him, so neji started pulling on hinata's shirt as he began to whine loudly.
"Someone's getting jealous hinata."
Hanabi said referring to her little cousin.
Hinata looked down at neji to see the toddler with tears in his eyes trying to grab hinata's attention.
"Neji mommy won't forget about you but you don't have to act this way"
Hinata said to neji which resulted in the toddler lowering his head.
"S sowy mommy."
Said neji.
......
Hinata sighed she knew that she couldn't give neji any more chances.
"That's not good enough neji I want you to sit on the bench with hanabi and think about what you have done."
Hinata picked up neji and she placed him on the bench with hanabi.
"So I guess I'm the warden."
Hanabi said a little annoyed.
"It's not like that hanabi"
Hinata says.
"Mommy no wan be hewe."
Neji tried to plea with hinata hoping she would let him off the hook like she usually does.
Hinata had realized that she had spoiled the baby too much to the point he formed habits.
.....
Hinata sighed.
"Neji you're in time out right so no playing for five minutes understand."
........
"Did you just give him a... punishment...wow."
Hanabi had her second surprise for that day.
"Bud mommy"
Neji was on the verge of tears he was shocked too he couldn't get out of punishment this time.
"No buts neji I told not to act that way and you did so now you're in time out."
Hinata said.
......
"Waaaaaaaaaaaaaaaah!!!"
Neji began crying he felt that hinata didn't want him anymore and that she only wants to take care of the baby.
"Just let him cry for a little bit hanabi he will be fine"
Hinata said as she doing everything in her power to not comfort the toddler.
"I'm impressed sis it's been one whole minute and you didn't try to comfort him."
So after good four minutes neji had stopped crying which had turned into nothing but mere sniffling.
.....
"Okay neji you can come play with us again."
Hinata motioned neji to come to her.
Neji climbed off the bench and he ran to sandbox.
"Now neji you know I have to watch the baby right."
Hinata said.
.......
"Yes"
Neji replied quickly.
"Then you remember what I said earlier."
Hinata asked neji.
....
"Yes."
Neji looked down.
......
"Sowy mommy."
Neji said.
"Neji don't say sorry to me, say sorry to naruto."
.....

"Sowy nawudo."
Neji said butchering naruto's name.
"Now why don't you give him a hug"
Hinata asked.
Neji groaned but he walked to naruto and gave him a hug.
"(Hey kurama watch this.)"
Naruto planted a small peck on neji's forehead.
Neji quickly shot up and started rubbing his forehead.
"Eww nawudo kissed me!!
Neji shouted.
"Aww that just means he likes you."
Hinata said
Naruto and kurama both begin to secretly giggle.
After hinata had stopped giggling she said
"Now that naruto forgives you why don't you play with him."
.....
"Otay we pway patty cake."
Neji sat infront of naruto and showed the baby how to play patty cake despite naruto already knowing how to play.
"Ou pway wike dat nawudo."
Neji said.
So neji and naruto started playing patty cake neji was starting to enjoy himself.
After a hour hinata's phone began ringing.
"Hello...yes father on our way...okay bye."
Hinata hung up her phone.
"It's time to go?"
Hanabi asked.
"Yes the meeting is done."
Hinata picked up naruto and she placed him in the stroller kurama jumped inside it and the group of five left.
(Hokage Estate)
The meeting had concluded minato and hiashi had came to a agreement.
"So we can draw up the papers now and I can present them at the next kage summit."
Said minato
Hinata opened the door.
"We're back father."
Hinata bowed.
Neji ran to hiashi.
"Untle untle we be hewe tommrow!!"
Neji asked excitedly.
"No neji."
Hiashi replied.
"Oh...me wan pway wi nawudo moe."
"Awwwwww you can play with anytime you want!!"
Kushina gushed
"Reawy"
Neji asked.
"Of course."
Kushina said.
"You don't have to do that that would be too much to ask for."
Hiashi said.
"No it's fine really hiashi."
Minato said.
.....
"Fine."
Hiashi said.
"Mommy mommy untle say me pway wi nawudo gan!"
Hinata giggled.
"Yes I know."
So after minato and hiashi shook hands the hyūga family left.
