One common theme is the vulnerability of Bella. When she's sick, it shows her in a more fragile state than usual, which contrasts with her strong - willed nature in the original series. Another theme is the protective nature of the Cullens. They go to great lengths to keep Bella safe and healthy.
The theme of family also emerges strongly. The Cullen family comes together to deal with Bella's sickness. This shows how they function as a unit, with each member having a role to play. It could be Carlisle using his medical knowledge, Esme providing a motherly touch, or the other siblings offering their own unique forms of support. It gives a deeper look into the family dynamics within the Twilight universe when faced with a crisis like Bella's illness.
Love and sacrifice are also common themes. The characters, especially Edward, may have to sacrifice their own needs or desires to take care of Bella. For example, Edward might have to put aside his own vampire - related activities to be with her constantly. And of course, the love between Bella and Edward, or even between Bella and the other Cullens, is emphasized more when she's sick. It's like their love is put to the test, and they rise to the occasion.
One common theme is the vulnerability of the usually strong characters. When a character in Twilight gets sick, it shows a side of them that we don't often see. For example, if a vampire gets sick, it challenges their idea of immortality and invincibility.
One common theme is the power of care and compassion. Carlisle taking care of a sick Bella highlights his ability to be gentle and nurturing. Another theme is the deepening of their relationship. When Bella is sick, it often serves as a catalyst for their connection to grow stronger.
One common theme is the concern of others. For example, Edward and the Cullen family are usually very worried about Bella when she's sick. Another theme is Bella's own struggle, both physically and mentally. She might be worried about how her sickness affects her relationships or her future in the Twilight world.
Another theme is the transformation of Paul's character. Often, in these fanfictions, he starts out as a rather rough or wild character, but through his relationship with Bella, he becomes more gentle and understanding. For example, in some stories, he learns to control his temper better. The third common theme is the idea of a different kind of pack dynamic. With Bella being involved with Paul, it changes the way the pack views her and also how they interact with Paul. It can create some interesting power struggles and alliances within the pack.

Love is another prevalent theme. Bella and Edward's love extends to their love for their child. And there's also the love of the Cullen family for the baby. Additionally, the theme of the baby's special abilities or powers is common. Because in the Twilight world, the baby is a unique hybrid, fanfictions often explore what these powers mean and how they affect the baby's life and the people around it.
Friendship is a common theme. Since Bella and Alice have such different personalities in the 'Twilight' series, fanfiction often explores how they can form a deep bond in various situations. For example, in some stories, they become friends despite their initial differences in the way they view the vampire - human world.
