Well, for their children's birthdays, they'd start the day with a family-only celebration at home. Hinata would give the child a handmade gift, something with deep emotional value. Then, in the evening, they'd have a party in the village square. Naruto would make a big speech about how proud he is of his child, and all the villagers would come to join in the celebration, bringing gifts and well - wishes.
In fanfiction, Naruto could take his kids on adventures around Konoha, showing them all the secret spots he used to go to as a kid. Hinata would be there to make sure they are safe and also to encourage them to explore their own abilities. She would also be the one to comfort the kids when they are sad or scared, while Naruto would boost their confidence with his positive energy.
It varies a lot. There are fanfictions where they have just one child, a very special one who combines the best of both Naruto and Hinata. However, in other fanfictions, they could have three or more children, each with their own unique personalities and ninja abilities. It really depends on the creativity of the fanfiction writer.
In fanfics, Naruto and Hinata's kids often have a special status. They are seen as both friends and role models by the other ninja kids. Their children might be more powerful or have unique abilities due to their parents' genes. So, they could be leading training sessions for the younger kids or helping them out during missions. At the same time, they also have normal friendships, like going to school together and sharing secrets.
In these fanfictions, Naruto's personality development can be seen in how he deals with domestic life. He used to be all about big adventures and saving the world, but now he focuses on the little things that matter to Hinata and their family. Hinata's shyness starts to fade as she gets used to being Naruto's partner. She starts to voice her opinions more, especially when it comes to protecting their home and loved ones. Their personalities grow together, complementing each other more and more as time passes.
Hinata's family would also have to deal with the emotional aspect. They love Hinata in her normal state, and now they have to adjust to this new form. They might start to remember when Hinata was actually a baby before and all the hopes and dreams they had for her then. Some of the more conservative members of the family might be more hesitant to let Naruto be around her, but the more open - minded ones could see that Naruto's presence is actually good for her in this state. And they would all be united in their goal to get Hinata back to her normal self.
In many fanfictions, Naruto starts to see Hinata not just as a friend but as a life partner. He begins to understand the depth of her love for him that was always there. This makes him more protective of her. Hinata, on the other hand, starts to come out of her shell. She becomes more involved in Naruto's world, perhaps even helping him with his ninja duties in some cases. Their relationship becomes a catalyst for their individual growth.
Writers often portray Hinata as a strong and determined character in the face of Naruto's darkness. She is usually shown as the one who stands by him no matter what. For example, she might be the only one who believes in Naruto when his dark side starts to take over. Hinata's shy nature in the original series can also be used in a different way. In fanfiction, it could be that her shyness is a mask for her inner strength which she uses to deal with Naruto's dark tendencies.
In Chinese folk tradition, there was a saying that went,"When the father is alive, he doesn't leave a beard, and when the mother is alive, he doesn't celebrate." This saying meant that children should not celebrate their birthdays while their parents were still alive. According to the ancient etiquette, people could only celebrate their birthday after they were 50 years old, which was also called "longevity". However, even if they did, it was best not to celebrate their birthday if their parents were still alive. This was because in ancient times, filial piety was very important. People respected and were filial to the elderly. Especially for a mother, her child's birthday was the hardest day because giving birth was very painful for a mother. Therefore, celebrating birthdays might be considered disrespectful and unfilial to their mothers. Although there was no mandatory requirement for birthdays in modern society, there was still a tradition of not celebrating birthdays in some rural families.
