Adventure is another theme. Given Vastra's nature as an alien and their combined skills, many fanfictions send them on exciting adventures, whether it's fighting supernatural threats or exploring new parts of their world.
Overcoming prejudice is also a significant theme. In the context of their relationship, they face prejudice due to their different natures and the norms of their society. Fanfictions often show how they rise above these prejudices and strengthen their bond as a result.
Love and relationship are common themes. Their unique relationship in a Victorian - like setting is often explored in-depth, showing how they support and love each other despite the odds.
One common theme could be family. Since it's about their baby, it might explore how they build and adapt to their new family structure. Another theme could be protection, as they would surely want to protect their baby from any threats in their fictional world.
Perhaps a story where they travel to an unknown land in search of a cure for an illness that is affecting the Silurian community. Along the way, they encounter new species and have to rely on each other's strengths more than ever.
You should focus on their unique relationship dynamic. Vastra is a Silurian with different values and abilities compared to human Jenny. Show how they complement each other, for example, Vastra's strength and wisdom with Jenny's loyalty and courage. Also, use vivid descriptions of the Victorian setting to set the mood.

There may not be a huge number of dedicated vastra and jenny baby fanfictions. However, you could start by looking at fanfiction communities on platforms like Tumblr. Sometimes fans share their own works or recommend others there. You can also check if there are any Doctor Who - related fanfiction groups on Facebook, as vastra and jenny are from Doctor Who, and ask for recommendations within those groups.
One common theme could be friendship turning into love. They might start as friends and then develop deeper feelings over time.
A common theme is the balance between her career and pregnancy. Since she is an officer, she has responsibilities, and the fanfiction might explore how she manages both. Another theme could be the reactions of the people around her, like other officers or the civilians in the Pokemon world.
A common theme is her growth as a wizard. Many fanfictions explore how she becomes stronger in her magic. Another theme could be her relationships, like her friendships or potential romances within the Fairy Tail guild.
A third common theme is secrecy. Given the nature of the Upper East Side society in 'Gossip Girl', many fanfictions have Chuck and Jenny keeping their relationship a secret at first. This adds an element of mystery and drama, as they have to hide their feelings and interactions from the ever - watchful eyes of the gossip - mongers in their world.
Common themes include the element of discovery. As they get to know each other better, they discover new things about themselves and each other. For instance, Ash might learn more about the law - enforcement side of the Pokémon world from Officer Jenny, and she might understand the passion behind Ash's Pokémon training. Another theme is the idea of protection. Officer Jenny could protect Ash from various threats in the Pokémon world, and Ash might protect her in return in his own way. And of course, there's the theme of love at first sight or slow - burn romance, depending on how the writer wants to develop their relationship.
