The relationship between Hiccup and Astrid during her pregnancy would be a journey of growth. Hiccup would have to be more patient as Astrid's hormones might make her moody at times. Astrid would rely on Hiccup more, which could be a big change for her. They would also start making plans for their family, like where the baby will sleep and how they will raise it. Their love would transform from the passionate love of two young adventurers to a more profound, family - centered love. They might also have some cute moments, like Hiccup talking to the unborn baby at night, which would make Astrid feel even more loved.
It develops gradually. At first, they might be just friends who respect each other's skills. But as they go on more adventures together, they start to notice little things about each other. For example, Hiccup notices how Astrid is always the first to volunteer for dangerous tasks because of her bravery. And Astrid sees how Hiccup's intelligence always gets them out of tough situations.
Their relationship might become more equal in some ways. As dragons, they are both facing a new and strange existence, so they have to rely on each other more. They might develop a new understanding of each other's strengths and weaknesses.
In the fanfiction, perhaps there's a moment when Hiccup gets injured while protecting the village. Astrid stays by his side day and night, taking care of him. She reads to him, makes him his favorite food, and in those quiet days, they realize how much they mean to each other. Their love deepens as they share these tender moments.
They could have a journey to find a special herb or something that is believed to ensure a healthy pregnancy in the world of How to Train Your Dragon. This would be an adventure filled with encounters with different dragons and terrains.
Hiccup would probably be very worried. He'd rush to her side immediately. He might start to check her injuries right away and call for help if needed.
Astrid might initially be in shock. She could just stand there, frozen, unable to believe that Hiccup is really gone. Her eyes wide open and her body trembling as she tries to process what has just happened.
In these fanfictions, their relationship often starts with Astrid being initially hesitant about her feelings. She might be tough on the outside but slowly realizes her love for Hiccup. Then they start having small moments together, like flying on their dragons side by side. These shared experiences gradually bring them closer.
There would be a shift in their dynamic as they prepare for a family. Hiccup, who is used to being adventurous, would have to focus more on home and stability. Astrid, while still strong - willed, would become more nurturing. They would need to find a new balance in their relationship, between their old selves and their new roles as parents - to - be.
Often, their relationship development in fanfiction is tied to their growth as individuals. Hiccup is constantly evolving in his understanding of dragons and his role in the village. Astrid is also growing in her acceptance of new ideas. As they both change, they find themselves drawn to each other more. They might start with a simple friendship, but as they witness each other's transformation, love begins to bloom.
During the pregnancy, their relationship would shift to be more centered around the upcoming baby. Hiccup would be constantly thinking about how to keep Astrid and the baby safe, especially with his role as a leader. Astrid would be dealing with the physical and emotional changes of pregnancy, and Hiccup would be her main support. This would bring out new aspects of their love for each other, like a deeper level of understanding and patience.
