They might become more protective of each other. Since they are both responsible for the baby, they would need to work together even more closely. Their love could deepen as they see each other in the role of a parent.
The arrival of the baby could also add some stress to their relationship. There could be disagreements on how to raise the baby, especially considering the unique situation of a half - vampire baby. For example, Emmett might be more lenient while Rosalie could be more strict. But through these differences, they could learn to communicate better and grow stronger as a couple.
The adoption changes their relationship in a profound way. Before, their relationship was mainly about their love for each other as partners. Now, they are parents too. This new role forces them to view each other in a different light. Rosalie might see Emmett in a more nurturing and responsible way, and Emmett might see Rosalie as an even stronger and more loving person. They'll experience new emotions together, like the joy of seeing the baby's first steps or the worry when the baby is sick, and these shared experiences will shape their relationship in ways they couldn't have imagined before.
Their relationship might become more nurturing. They would have to work together to take care of Bella, which could strengthen their bond. They would be sharing responsibilities and decisions about her upbringing, which could bring them closer.
They would become more protective. Stefan, who has always been somewhat of a protector, would be even more so. Bonnie would also be very protective but in a different way, using her magic to safeguard the baby. Their relationship would deepen as they are united in their love for their child.
Their relationship would likely become more centered around the baby. They would have to cooperate even more closely to take care of the little one. There would be less time for their own personal issues as the baby's needs would be top priority.
With the baby's arrival, they would have less time for just the two of them. But this could bring them closer in a different way. Spock might become more in touch with his emotions because of the baby, and Uhura would be more understanding of Spock's Vulcan side as they navigate parenting. For example, when the baby has a fever, Spock uses his Vulcan knowledge to try and cool the baby down, and Uhura is impressed by his calmness and resourcefulness.
The arrival of the baby could deepen their emotional bond. They have to communicate more about parenting decisions, which might lead to some arguments at first, but as they work through them, they understand each other better. They also might start to see each other in a new light, like Tony seeing Ziva as an amazing mother, and Ziva seeing Tony as a really committed father. This could lead to a more stable and loving relationship overall. It's like they have a new shared purpose that ties them even closer together.
The twin could create jealousy in Rosalie if Emmett shows too much interest in the new character. Since Rosalie is very protective of her relationship with Emmett, any threat, even if it's just a perceived one from her twin, could cause a rift between her and Emmett. On the other hand, it could also strengthen their bond if they work through it together.
Their relationship can become more protective. Logan will be extra vigilant about keeping Rogue and the baby safe. Rogue might become more dependent on Logan in some ways, especially when it comes to physical protection. Also, they might have more tender moments as they take care of the baby together.
One idea could be that the baby has a special power. For example, it might be able to communicate with animals in a way that surprises everyone in the family. Another plot could revolve around the challenges of raising a half - vampire baby, like finding suitable food sources that won't harm the baby or its development.
Well, in fanfiction, Rosalie and Emmett's daughter could have a very different personality from her parents. Maybe she's more of a peacemaker compared to Rosalie's sometimes fiery nature. She might befriend humans more easily, which could cause some tension within the vampire family as they try to keep their existence a secret. It could also lead to her having her own set of adventures, like trying to find a way to co - exist with humans without breaking the vampire laws.
