One character often paired with Emma could be her mother. Their relationship can be a central focus, showing how her mother cares for her as a baby and the bond that develops over time. Another could be Henry. They have a special connection in the 'Once upon a time' universe, and in the fanfiction, he might play an important role in Emma's life from an early age.
A baby fanfiction about Emma and Hook could involve their journey into parenthood. Maybe it would start with the discovery of Emma's pregnancy. They'd have to deal with the joys and fears that come with it. Hook might be overprotective, given his past losses. And they'd face challenges from the magical world they live in, like protecting the baby from dark magic threats.
Some fanfictions might explore the idea of Baby Emma having some latent magical powers that start to show at a very young age. This could lead to all sorts of adventures and challenges for her family as they try to understand and control these powers, all while keeping her safe from those who might want to use her powers for their own evil purposes.
Often, there could be themes related to magic and fantasy. Since 'Once upon a time' is often associated with such elements. Emma might be depicted as having some special powers even as a baby, and the fanfiction could explore how she discovers and controls these powers as she grows. It could also involve themes of friendship, as she meets different people who become important to her throughout her life.
A baby fanfiction would likely strengthen their relationship. Having a child together means they have a new bond. They'd have to rely on each other more, like when taking care of the baby at night or dealing with the baby's first magical outburst. Their love would grow as they see each other in new roles, as parents.
Snow White and Prince Charming are obvious choices. As her parents, they play a crucial role in Baby Emma's life. Their love for her and their efforts to protect her can be explored in great detail.
It could be Hook. Given their relationship in the show, it's quite possible that he is the father. Their chemistry and the storylines they had together make it a likely scenario.
There's also a fanfic titled 'The Snow Queen's Redemption'. In this story, the Snow Queen is not entirely the villain. Emma discovers there are more layers to her, and they end up forming an unlikely alliance. It's really interesting to see how their characters develop together throughout the story.
In some fanfictions, Emma and Regina could develop a romantic relationship. Their complex history would add depth to such a story. They might have moments of jealousy when other characters show interest in one of them, and then have to confront their true feelings for each other.
One great Hook Emma fanfiction is 'A Pirate's Heart'. It beautifully captures the chemistry between them. The story takes them on an adventure where they have to face many challenges together, which deepens their relationship.
