Here's another option: "...Nabi takes care of his paralytic boss by feeding and cleaning him, reading him stories, and dealing with all the tiny details of daily life." Before "the details of daily life", you need a verb which means "take care of" (I chose "dealing with") because the parallel structure starts with "feeding". You can reduce pronoun use through parallel structure, like I did. I couldn't do it with "reading stories" because you need an indirect object not a direct one.

Thanks Denis :)
