There are quite a few out there. In some fanfictions, like 'A New Beginning for the Hook - Swan Family', it delves into how their relationship evolves with the addition of a baby. It might show Hook being overly protective and Emma being the more practical one when it comes to raising their child. The story could also involve their friends from Storybrooke helping them out in different situations.
There could be a fanfiction where their baby is the key to saving the Enchanted Forest from a new dark curse. In this story, the baby has a special connection to an ancient magic that only it can unlock.
You can try fanfiction websites like Archive of Our Own (AO3). It has a large collection of fanfictions, and you're likely to find many about Captain Hook and Emma Swan having a baby there.
A great one is where their baby is kidnapped by an old enemy of Hook's. This story delves deep into Hook's past and how he and Emma work together, using their combined skills and love for their child to get the baby back. It also has some really heart - warming moments between them as a couple and as parents. There are many plot twists and turns that keep you on the edge of your seat throughout the story.
I also like 'Swan and the Pirate'. It starts with an encounter between them that sets the stage for a deeper connection. The story weaves in elements from the original show but adds its own unique twists. It has some beautifully written scenes that make you root for their relationship to work out.
One popular Emma Hook baby fanfiction might be 'The Unexpected Arrival'. It often explores how Emma and Hook adjust to having a baby in their lives. It could involve cute moments like Hook trying to change diapers clumsily while Emma watches with amusement.
One great fanfic is 'The Pirate's Heart'. It delves into a romantic relationship between Captain Hook and Emma Swan in a very engaging way. The story has a lot of adventure elements combined with their growing feelings for each other.
Adventure is also a big theme. They are often on some sort of quest or journey together. For example, they might be searching for a magical artifact while also dealing with their feelings for each other. And there's also the theme of trust. Since they come from different sides, learning to trust each other is a crucial part of many fanfics.
One common theme is redemption. Captain Hook often has a past full of misdeeds, and in these fanfics, his relationship with Emma Swan can be a part of his journey towards redemption. For example, in many stories, he tries to change for her.
Perhaps they are in the middle of a new adventure when Emma realizes she's pregnant. This could add a whole new layer of tension as they not only have to deal with the external threats but also ensure the safety of the baby. They could seek help from their friends in Storybrooke, who have mixed reactions to the news.
In another scenario, both Captain Hook and Emma Swan are held for ransom by a new and powerful villain in their world. They have to work together, using their combined skills and the power of their relationship, to escape from captivity. This could involve Hook using his pirate wiles and Emma using her magic. They might also find unexpected allies along the way who help them in their quest to avoid paying the ransom and defeat the villain.
