In NC I have been unable to find a private pyschologist, psychaitrist etc.. To observe my sons behavior before and after a visitation with father. I do not understand the aggressive and violent behavior he immediately displays at home,daycare and toward me. He starts waking up each night and crying and screaming as long as he has visitation, as soon as it stops the violence, nighttime screaming and crying and behavior toward me returns to normal. I need help with finding a qualified doc.

You need to go to Court, explain the problem, file to end the visitation (or limit it) and ask the Court to APPOINT someone to examine your child.
