I think my youngest daughter (10) is an INFJ, although it's too early to tell. She is the most intense, willful, manipulative, independent, moody, difficult child I've ever run into. (She's also unbelievably sweet and affectionate--I love her dearly). I really had to change my parenting style to deal with her, although it's still a struggle. A friend has a daughter who's in college now who I also think is INFJ, and my friend tells me that she was also a holy terror as a child and that she had to get very, very tough with her. I was pretty shocked when she told me this because the girl is very easy-going and well-mannered now. Where I'm going with all this is that I'm guessing that most INFJ's are very, very intense as young children, but parents and the community come down pretty hard on these poor kids and pretty much discipline the life out of them. My parents were very strict disciplinarians with me -- much more so than I ever was with my kids. It would be great if all this energy and intelligence could be channeled more creatively, but I know with my own child I'd never have time or energy for anything else.
