I just wanted to say one thing... not every child that has issues can be defined as having RAD. ODD is common as well (20% of all school children supposedly have it). My concern is that Autism and everything under that umbrella, RAD, ODD etc... can sound similar; however, they are treated differently and are definitely a different diagnosis.
Agreed - but it starts with the history of the child from birth - onward. Once that is completed - situations and circumstances can be drawn to see exactly where the child fits...
I put this info out there because there are parents adopting - but also - there are parents neglecting their children - and someone here may be a teacher or dr - or service professional that works with children — this will at least begin to identify and help heal the child for a successful life...
