There are three categories of RAD (Reactive Attachment Disorder). Our oldest daughter falls into category 3- No Attachment. You can read more on page 24 of this article by clicking on the link below. If you’re not already aware of this, we adopted our oldest daughter from an orphanage in Russia and brought her home at age 23 months. She was prenatally exposed to alcohol and shows all signs of neglect and abuse from life in an orphanage. She’s 10 now and attends the Jasper Mountain School.
