"As parents, INFJs usually are fiercely devoted. A female INFJ, particularly, is linked to her children in a way different from the other types: with almost a psychic symbiosis. This deep bond can create an over-dependency that can be unhealthy for both mother and child. At the same time, INFJs tend to be good friends with their children, while firm in discipline. They usually are concerned about the comfort of a home and most especially the comfort, physical health, and emotional well-being of both mates and children."
This sounds about right to me. I'm looking forward to hopefully one day being a parent, though hopefully I'll avoid the over-dependency stuff. I know raising a child will be a lot of work but from what I hear it is a connection like no other.
I think INFJ parents would excel in appreciating their child for the person that they are, as opposed to the person that the parent wants the child to be.
