One possible plot could be that Jack, with his carefree and fun - loving nature, and Elsa, with her strong and protective side, discover they are having a baby. They could face challenges like how to combine their two very different worlds. Jack's world of eternal winter playfulness and Elsa's more regal, ice - castle - based world. They might worry about how their baby will inherit their powers and whether they can keep their child safe from those who might want to use the baby's powers for evil.

Well, perhaps the fanfiction could be about how the baby brings Anna and Elsa even closer together. Since they already have a strong bond, the baby could be like a little miracle that makes their family complete. The story could show their daily life taking care of the baby, like singing lullabies and teaching the baby to walk, with a lot of cute and heart - warming moments.
One possible plot could be that Elsa and Hans, after many challenges and reconciliations, decide to start a family. Their baby might inherit Elsa's ice powers in a unique way, like being able to create ice sculptures just by touch. And they would have to protect the baby from those who might fear or want to use the baby's powers for their own gain.
They would become more united. Having a baby would make them a family, and they would support each other more closely in taking care of their child.
Perhaps Hiccup is on a journey to explore new lands and stumbles upon Elsa's frozen kingdom. He helps Elsa overcome some of her fears about her powers that have resurfaced.

They also have to figure out how their baby will inherit and control both dragon - related and ice - based powers.
Well, perhaps a power - hungry wizard from a neighboring magical realm. He hears about the baby's unique powers that combine Jack Frost's and Elsa's abilities and wants to harness that power for his own evil plans.

But with the love and guidance of its parents, it could learn to use its powers for good and become a beloved figure in the winter - themed magical world.
Well, perhaps the plot could involve Jack and Ianto facing the challenges of raising a baby in a world full of danger and mystery. They might have to protect the baby from various threats while also dealing with their own relationship dynamics.
