Well, without actually reading the fanfiction in question, it's difficult to say exactly. It could be that the author is exploring a darker side of the relationship between Nico and Hades, perhaps for the sake of creating drama or exploring certain themes like power imbalance or trauma. Fanfictions often take existing characters and put them in new and sometimes challenging situations.
Another theme is the exploration of the Underworld. Given Hades' domain, many 'baby nico and hades fanfiction' stories take the opportunity to describe the Underworld in detail, with Nico being the newcomer and learning about this strange place. It can be about the different regions, the creatures there, and the rules that govern the Underworld.
Well, in a lot of these fanfictions, Hades might be overprotective in terms of Nico's social interactions. For example, if Nico wants to make new friends among the demigods, Hades might be hesitant and try to limit it. He could be worried that Nico will get hurt either physically or emotionally. Also, when it comes to Nico's training or using his powers, Hades might be overly cautious and not let him push his limits as much as Nico wants to, fearing that he could lose control or get injured in the process.
