Sasuke would likely be initially shocked. He's a man who has been through a lot and is used to a life of solitude and danger. But then, a sense of protectiveness would kick in. He'd become more vigilant about the safety of Sakura and their unborn child. He might also start to think about how to be a better father than his own was, in some ways, trying to break the cycle of his family's past.
Sarada might be initially shocked and sad. She loves both her parents, and the divorce would be a huge blow to her. She could become withdrawn for a while, not wanting to talk to her friends about it.
One great Sasuke, Sakura, Sarada fanfic is 'A Family's Bond'. It beautifully portrays the family dynamics between them. The story shows Sasuke's growth as a father, Sakura's strength as a mother, and Sarada's journey to understand her family better.

Another plotline could be that a new threat emerges in the ninja world that specifically targets the Uchiha clan. Sasuke, Sakura and Sarada have to work together to protect their family and the village. This would not only show their family bond but also their loyalty to their home. There could be intense battles and emotional moments as they face this new danger.
One idea could be a story where Sarada discovers a hidden jutsu that her father Sasuke once used. Sakura helps her understand the medical implications of using such a jutsu. They train together and bond over it, strengthening their family ties.
One idea could be a story about Sarada training with Sakura and Sasuke. Sarada is eager to learn new jutsu and Sakura teaches her some medical ninjutsu while Sasuke shows her some of his signature moves. This would be a great way to explore the family dynamic and how Sarada grows as a ninja with the help of her parents.
She might be initially heartbroken. Sakura, being in love with Sasuke, would surely be deeply affected when he neglects her. She could become withdrawn herself, losing some of her usual cheerfulness.

For example, when Sarada is in trouble, Sasuke and Sakura will put aside their differences and come to her rescue.
