Exactly. It's not trust. The hugs are superficial as are the words. They are dangerous children. After my experience, I truly don't believe it's worth it for anyone with other children to take a chance exposing that child to the Reactive Attachment Disorder (RAD) kid. They are very sneaky and basically, as parents, we don't know what they do, even when we think we are keeping a good eye on them. If people really want to keep the k ids at home, you need to have videocameras in every room and alarms on their doors in case they want to leave their room in the middle of the night to perp on a sibling. It is like setting up a mini-Residential Treatment Center (RTC) in your home. It's not fun, but it's necessary. They can not be left alone with other children or pets. Ever.
If anyone chooses to trust these kids, you were warned.
