i mean the small fictional flying, wish granting type of fairy. i was planning on writing a childrens book on them and was wondering how many generations i would need to create and as some people actually believe they exist i thought there may be a general rule as to their life expectancy.
I don't think those ones do a lot of reproducing, so it's sort of as if they live forever. Peter Pan is the only place I can think of where they might die (but don't)
