The relationship could start with Percy and Annabeth being overprotective parents. Percy might be constantly worried about the baby's safety near water, while Annabeth would focus on teaching the baby knowledge and wisdom. As the baby grows, they could start to have little adventures together. For example, the baby could go on a mini - quest with them around Camp Half - Blood, which would strengthen their bond.
Well, there might be a 'baby Percy fanfic' that delves into how the gods were already aware of Percy even as a baby. It could explore their secret plans regarding him. Or perhaps a story where baby Percy has some sort of premonition or special power that only shows up in his infancy, and the fic could be all about how those around him try to understand it.

The Titans could be antagonists. Even though they have been defeated before, some of them might hold a grudge against Percy and Annabeth and see their baby as a new target for revenge. They could try to kidnap the baby to use it as a bargaining chip or to corrupt it to their side.
One possible plot could be Percy and Annabeth adjusting to life as new parents. They might face challenges like protecting their baby from mythological threats. For example, they have to keep the baby safe from monsters who might target the child because of its parents' heroic status.
Well, it could be that Artemis sees Percy as a special child with great potential. Maybe Percy's parents are unable to take care of him for some reason. Artemis, being the goddess she is, decides to take him under her wing. She might teach Percy all about her ways, like archery and hunting. And Percy, growing up in this unique environment, could develop powers or skills different from his normal fate in the original stories.
In the beginning, Artemis would be the strict but loving adoptive mother. She'd teach Percy everything she knew. Percy would look up to her with admiration. But as he gets older, he may want to explore his own identity more, especially his connection to Poseidon. This could cause some strain in their relationship. However, through various adventures and challenges, they would come to understand and respect each other more, and their relationship would become more of an equal partnership in the end.
In fanfictions, Poseidon often interacts with baby Percy in a very gentle and protective way. He might use his powers to create a safe environment for Percy, like a special underwater grotto where Percy can be hidden from danger. Sometimes, he sends sea creatures to watch over Percy, like dolphins or friendly sea nymphs.
In a Percy Jackson baby sister fanfic, she could have some really cool adventures. Maybe she discovers she has her own unique powers early on, like being able to communicate with sea creatures in a different way than Percy. She could also get into trouble by wandering into the wrong part of the camp, like the restricted areas where the more dangerous magical items are kept.
Her power could be related to healing. Since the demigods often get injured in their battles and adventures, having a healer in the family would be a great advantage. She could use her power to heal not only Percy but also other demigods. This would make her very popular in the camp and also attract the attention of the gods. Some gods might want to use her for their own purposes, while others might want to protect her because of her valuable gift.
