What was your experience with your entities/demons for those who worked with them as kids/teens?

Some people told me that they started to work with demons/entities (correct me if I misuse the terms) quite young while others told me that those entities refused to work with them until they were adults.

Could you explain to me why some of them chose to make you wait, and for those who didn’t have to wait, could you share your experience with them? I’m curious to know what kind of teachers they are (or coworker), but I also know that all my questions may have multiple answers; that’s why I’m asking anyone who’d like to share their personal experience to do so!

I also wondered (sorry, there’s a bunch of questions) why some of them are protective towards children?
