One popular plotline could be about the challenges they face as new parents. For example, Naruto might struggle to balance his Hokage duties with being a father. Hinata, on the other hand, could be dealing with the pressures of raising a child with such a high - profile father. Another plotline might involve their baby showing some unique ninja abilities from a very young age, and they have to figure out how to train and protect the child at the same time. There could also be a plot where their baby gets kidnapped by an old enemy seeking revenge on Naruto, and they have to embark on a dangerous rescue mission.
In some Hinata and Naruto baby fanfiction, there's a plotline about the baby inheriting a special power. This power could be related to Hinata's Byakugan or Naruto's Nine - Tails chakra. The story could then revolve around how they help the baby control this power. There could be a sub - plot where the other villagers react to the baby having such a powerful ability. Some might be scared, while others see it as a great asset for the future of the village. And of course, Naruto and Hinata would be there to support and protect their baby through all of this.
One popular plotline is that Naruto and Hinata travel back to the time when the Uchiha clan was still intact. They try to prevent the massacre from happening, which changes the whole future of the ninja world. Another plotline could be them going back to their childhood days.

Another plotline could be Hinata's internal struggle. She's always been in love with Naruto, but when he starts to show interest, she has to overcome her shyness and self - doubt. For example, in some fanfictions, she might doubt if Naruto really loves her or if it's just a passing feeling.
Well, in some fanfics, there's a plotline where Hinata loses her memory and Naruto has to make her fall in love with him all over again. It's a classic but still very engaging. There are also stories where they are arranged to be married for political reasons at first, but then they actually fall in love for real during the process. And a really unique one is when Hinata becomes a super powerful ninja overnight and Naruto has to deal with his feelings of being a bit overshadowed while also being proud of her.
One interesting plotline could be Hinata becoming a powerful ninja in her own right and protecting Naruto instead of the other way around. For example, she could master a new and unique jutsu that saves Naruto from a powerful enemy.
A popular plot in such fanfictions could be a 'what - if' scenario. What if Naruto had a different upbringing? How would that affect his relationships with Sakura and Hinata? Some fanfictions explore this by making Naruto be raised in a different village for a while. Another plotline could be that Sakura discovers a new medical ninjutsu that can enhance the abilities of Naruto and Hinata, and they embark on a journey to perfect this new technique. And then there are those fanfictions where Hinata has a secret power that she reveals during a critical moment when she, Naruto, and Sakura are in danger, changing the course of their adventure.
One possible plotline could be a story where Naruto has to choose between two versions of Hinata, the original Hinata and a version from an alternate RTN (Road to Ninja) universe.

This adventure would test their skills and bring them closer together.
Another plotline might involve Naruto being a bit of a slacker in college at first, while Hinata is a studious student.
