The relationship would likely become deeper. Hook would be more protective of Emma, always by her side. Emma might see a new side of Hook, a more tender and responsible side, which would make her fall more in love with him.
As Emma is pregnant, there would be more emotional vulnerability between them. They would have to communicate more about their fears and hopes for the future. For example, Hook might share his insecurities about being a father, considering his past as a pirate, and Emma would reassure him. This would strengthen their bond.
Their relationship could also face some challenges. Maybe there are different ideas about how to raise the child. Hook, with his pirate background, might have some unorthodox ideas, while Emma, being the savior, wants to raise the child in a more 'normal' way in Storybrooke. But through these differences, they learn to understand each other better and grow closer as a couple expecting a baby.
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.
Hook might become more protective and less reckless. His focus could shift from his own adventures to safeguarding Emma and the baby. Emma, on the other hand, could become more in touch with her softer side. She has always been strong and independent, but now she has to rely on others more.
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.
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.
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.
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.
Well, they could start by relying on each other's skills. Hook's knowledge of Neverland and his sailing expertise, combined with Emma's magic, would make them a formidable team. As they face danger together, like escaping from a giant sea creature or finding a way through a maze in the jungle, they start to trust each other more, which deepens their relationship.
One idea could be that they face challenges in their relationship while preparing for the baby. Maybe Hook is worried about being a good father because of his past. Another could be that Emma's magic has an unexpected reaction during her pregnancy, like protecting the baby in a magical way. And a third idea is that they discover a prophecy related to their unborn child which forces them to go on an adventure to protect their family.
