In these fanfictions, Sasuke often becomes more responsible. He was once a brooding and solitary ninja, but as a baby daddy, he has to think about someone other than himself. For example, he might start to plan for the baby's future, which is a big change from his usually self - centered ways.
One popular Sasuke baby daddy fanfiction could be 'Sasuke's Unexpected Fatherhood'. In this story, Sasuke might face challenges in adjusting to being a father while still dealing with his ninja duties. Another could be 'Sasuke and the Newborn', which may focus on his relationship with the baby and the mother. There's also 'Sasuke's Fatherhood Journey' where his growth as a father is explored in detail.
Sasuke would likely become more protective. Usually Sasuke is very focused on revenge and his own power, but when faced with baby Itachi, he would feel the need to shield him from all harm. His cold exterior might soften a bit as he looks at the innocence of baby Itachi.
Sasuke becomes more gentle. Usually he is cold and aloof, but with baby Sakura, he has to be soft. He shows more patience as he takes care of her needs, like when she cries and he tries to figure out what's wrong.
Many fanfictions show Sasuke's sadness through his flashbacks. He constantly relives the day his clan was massacred, and these memories haunt him. Writers often use these flashbacks to highlight his internal pain, which affects his relationship with Sakura as he sometimes pushes her away because of it.
Well, fem Sasuke might be more in touch with her emotions compared to the original Sasuke. She could show vulnerability more easily. Naruto, on the other hand, might become more protective. For example, he might be quicker to jump into a fight if fem Sasuke is threatened.
Their relationship would likely become more intimate and committed. With a baby on the way, Sasuke would feel a greater sense of responsibility towards Sakura. He might be more protective and stay closer to her.
Sasuke's determination and focus can be passed on to their baby girl. He may set high standards for her in terms of her ninja skills (if in the Naruto - like universe). However, Sakura will be there to remind him that the baby girl also needs a childhood filled with love and play. Sakura's nurturing nature will ensure that the baby girl feels loved and cared for at all times, while Sasuke's more serious side will push her to be strong and capable.
In many fanfictions, their relationship develops through shared experiences. For example, they might go on a mission together and during that time, Sasuke starts to see Sakura in a new light. He realizes how strong and reliable she has become.
In this fanfic, Sasuke's character would change in terms of his cold exterior. He would soften up a great deal. He might start smiling more often, especially when he is around Sakura. His actions would also be more focused on pleasing her rather than just his own goals. For instance, he might accompany Sakura to the hospital where she works just to be with her, which is a big change from his usually self - centered nature.
Sasuke would probably be very guarded at first. He's not used to dealing with something so innocent and vulnerable. He might be suspicious of the baby's presence and think it's some sort of trap.
