One possible plot could be that Sakura has a difficult birth. Naruto is by her side, worried sick. Their friends from the village are also there, waiting anxiously. Maybe there are some complications during the birth, and Sakura has to draw on her inner strength as a kunoichi. And in the end, she gives birth to a healthy baby, which brings great joy to the whole village.
The fanfiction could start with Sakura realizing she is about to give birth. Naruto might be on a mission far away at first, and Sakura has to rely on her friends like Ino and Tsunade. As the birth approaches, Naruto manages to rush back just in time. The baby's birth could be a symbol of new hope for the village. It could also lead to new adventures as the parents now have to balance raising a child and their ninja duties.
In a fanfiction of Sakura giving birth, it might explore how Naruto and Sakura's relationship evolves during this time. Naruto could be super protective and constantly trying to make Sakura comfortable. The story could also focus on the anticipation of the new life. What kind of ninja will the baby grow up to be? Will it inherit Sakura's medical skills or Naruto's powerful jutsu? There are so many possibilities.
Perhaps the fanfiction focuses on how the baby changes the relationships in Naruto's life. Her relationship with Sasuke could be affected, whether they are friends or something more. The baby could also bring new unity among the ninja villages as everyone comes together to protect the new life. And the story could explore how female Naruto passes on her ninja values to her child from a very young age.
It could be a mix of both. The baby might have Naruto's hair color but Sakura's eye shape. In terms of personality, it could inherit Naruto's courage and Sakura's kindness. This would make for an interesting character in the fanfiction as it combines the best of both parents.
One possible plot twist could be that Anko discovers the baby Naruto has some unique and unexpected powers right from birth. Maybe powers that are not shown in the original Naruto story. For example, he could have an instant connection to snakes like Anko, which could lead to a whole new arc in the fanfiction about him learning to control this power and how it affects his relationship with others in the Hidden Leaf Village.
The plot could revolve around the build - up to the birth. There might be some pre - birth challenges like Sakura having to take a break from her ninja duties and Naruto having to take on more responsibilities in the village. Then comes the day of birth. Sakura goes into labor and the whole village is on edge. Naruto is right by her side, and they both experience the joys and pains of bringing a new life into the world.
Their child would be a very interesting mix. Genetically, it's a really strange concept as they are not originally paired in the series. But if we consider it in the fanfiction world, the child might inherit Naruto's strong will and Sakura's medical and combat skills. Maybe it would have bright blond hair like Naruto and Sakura's green eyes. And it could have a unique chakra nature that combines Naruto's Uzumaki chakra with Sakura's possible chakra nature.
One possible plot could be that Snape discovers he has a unique magical ability that allows him to carry a child. He might keep it a secret from everyone in Hogwarts due to fear of ridicule. As he nears the time of giving birth, he would have to find a secluded place within the castle or in the Forbidden Forest. He would endure the pain alone, using his own potions and magic to ease the process as much as possible.
Perhaps in the 'harry gives birth at dursleys fanfiction', there's a new form of magic introduced. Harry could have been affected by a magical experiment that causes this strange phenomenon. The Dursleys, who have always mistreated Harry, now have to face the consequences of having such a unique and unheard - of event happening in their house. They might be in a state of panic and confusion as they try to figure out what to do.
The plot could also involve the father of the baby being a mysterious figure. Maybe he's from a far - off land that Elsa visited during her adventures after the events of the Frozen movies. And as she gives birth, the baby could inherit some of her ice powers, which would lead to a whole new set of challenges and adventures for Elsa as a mother, like teaching the baby to control its powers from a very young age.
Perhaps it could involve some sort of magical or scientific experiment gone wrong that results in Tony being able to give birth. Peter could be the result of a genetic manipulation within Tony's body, and the story might then focus on how they adapt to this strange new situation.
One possible plot could be that Rachel gives birth during a big performance. Maybe she has been hiding her pregnancy from most of the glee club members, and right in the middle of a huge show, her water breaks. This leads to a chaotic but heartwarming situation where her friends rally around her, turning the backstage area into an impromptu delivery room while still trying to keep the show going in some way outside.
