(s/n) - son's name

It was yet another day in the large household where (f/n) lived with her husband, her son, her husband's siblings and her good friends that happened to work under her sister-in-law. The (h/c) head followed the Baltics around, helping them cleaning the hall so they could finish before it was lunch time; she had left (s/n) with Nikolai, she honestly thought, despite everything Annya said, that the two needed to spend more father-son alone time.

Just like usual, the trio tried to refuse her help by saying that she had more things to do, such as taking care of the 5 year old boy or avoiding Belarus to throw knives everywhere around while 'training' (no one believed that), but the girl always ignored their words and proceded to help the best she could.

While his wife was busy with all the cleaning, a certain silverette stood at the side of his bed, his gaze locked on the child's violet eyes.
"Mama." stated the (h/c) haired boy; Belarus' glare intensified.
"Mama isn't here!" he said.
"Mama." repeated the child. "I want mama!"
"Mama is busy!"
"Call mama!" ordered the five year old.
"No!" responded Nikolai.
"I want mama!" demanded the kid. "My mama!"
Unknown to them, Annya, who had been watching the scene along with Dmitri, went to fetch the only other female in the house.
"Your mama?" wondered the silver head, emphasizing the word 'your'.
"Da!" nodded the small boy. "My mama!"
"Mama is not yours!"
"Da, mama's mine!"
Still without them noticing, Russia had returned to watch the unfolding of the scene; dragging her sister-in-law with her, Annya moved to stand by Ukraine's side.
"Nyet, mama's mine!" Nikolai interjected.
"Mine!"
"Mine!"
"Mine!"
"Mine!"
"Mine!"
"Mine!"
"Mine!"
"My woman!" stated Belarus.
"My mama!" (s/n) attempted copy his father's growl, but the sound he made was so adorable that it caused a chuckle to reverberate in Dmitri's chest and sent the women into a fit of silent giggles.
"Mine!" Nikolai claimed.
"Mine, not papa's!" (s/n) disagreed.
The sight of the two was the most adorable of things. The two looked into each other's eyes fiercely, the father with a cute frown and the child with a cute pout and puffy cheeks; but the ultimate piece was that, aside the hair colour, (s/n) was the spitting image his father.
"Da, mama is papa's!" Nikolai stated.
"Nyet!"
"Da!"
"Nyet!"
"Da!"
"Nyet!"
"Da!"
"Nyet!"
"Da!" the two were now touching their foreheads as they glared fiercely at each other. (F/n) knew that Nikolai would never hurt (s/n), not on purpose, but, just in case, before things got out of hand and the boy ended up falling from the tall bed of his parents or something, she stepped in front.
"Alright, enough fighting!" she stated, closing the distance between them and herself; both father and son turned their heads simultaneously at the sound of her voice.
"Mama!" called the small boy, stretching his arms towards his mother as if asking her to pick him up; noticing this, the silver head reached for his wife's hand, in a hope to grab her before she picked their child up. Just as Belarus pulled (f/n) to him, (s/n) had grabbed her arm and was now hanging on his mother's limb.
"Mine!" they both shot at the same time. In the doorway, Annya and Dmitri laughed at the event.
"Boys, boys, boys!" said the (h/c) head, gaining attention from both. "I am your mother and your wife..." she stated, pointing at each of them. "...I own myself, and I don't want more jealousy fights, get it?"
"Da, mama!" "Da, (f/n)!"
"Good, now come on. It's lunch time!" she announced, picking up (s/n) properly and passing him to Nikolai's hold; she walked away, the others following her to the dining hall.
Behind (f/n), father and son continued their fight of glares under the amused gaze of Nikolai's older siblings; somehow, the (e/c) eyed female picked up on the tension a couple of meters behind her.
"Stop it boys, you have to learn how to behave for the little one!" her statement seemed to caught everyone, except Annya, out of guard.
"What little one?" Dmitri wondered.
"Oh, I went to the doctor a while ago, he thinks this time is a girl!" explained the (nationality). Understanding her words, the glare of the two intensified even more and two shouts echoed through the household:
"My sister!" "My daughter!"

"This is going to be a nightmare..." (f/n) sighed as Russia patted her back apologetically.
