I guess I don't have a specific question but could always use more tips... my 6-yr-old is an INTJ like his dad. So at least we were a little prepared for the challenges posed by our wonderful little boy. He started having problems this year (first grade) and his teacher suspected they stemmed from his being typed as a "Green" personality (which sounds the same as an INTJ). So DH and I did a bunch of reading and research - like a typical INTJ & INFJ would - and discovered his classroom issues were perfectly normal for his type. (Nurture by Nature - Tieger)
The biggest problem now is having to "run interference" with family members or other people who "deal" with him on a regular basis. We try to explain that he's not intentionally being rude (open) or mean-spirited(honest)... and they just think we're making excuses for bad behavior. As a mom, it makes me want to sequester him away! I think I must project some of my own hurt feelings on him though, especially when people accuse him wrongly of things... at least he has thick skin!
Anyway, we plan to put him in Montessori school next year and I expect that to help in the classroom. All we can do with the rest I guess is continue to work on the relationship training with him.
