I found this interesting study that shows parental tendencies that resulted in more narcissistic children by "overvaluing" their own children. These types of studies are always so interesting to me as a teacher, as we get all kinds of students--some who undervalue themselves, some who are on point, and some who overvalue themselves. It's hard to say whether it's nurture or nature, but this study seems to point to nurture.
