narcissistogenic

Parental behavior resulting in the development of narcissistic tendencies in the child. Usually this behavior includes over-adultation, spoiling and improper punishment of the child, amongst others.

May be seen as similar to "schizophrenogenic" parents, except they produce narcissism and not schizophrenia.
