As far as the support goes...
"NA worked with K and her parents between October 2009 and December 2010 (just over a year but we do not know how often they saw her, do we?
"When she began working with the family...NA... knew nothing about attachment disorders. By reading and arranging to go on courses...NA.... took positive steps to learn about attachment disorders. Her industry and her commitment to this family are highly commendable."
So this was not a person who came into the situation able and ready to help. She obviously did a good job and showed a lot of commitment personally but let's be honest, why was no person already experienced in these issues not provided!?
Don't apologise Spero, for posting this link onto this thread... I think it is good for those of us who are adopters to chat about the 'issues', those especially affected may pick up tips/hints/even sanity saving ideas, and the casual reader may be able to influence the world for good!
So a casual reader might not want to blame adoptive parents for all mistakes they make, knowing we are all human and there really are no such things as exceptional parents (well not sure I've met any!)
Maybe readers will be demanding better post adoption support for all adopters. Asking their MPs to support things like better support and keep our politicians accountable.
Maybe even if appropriate offering themselves as respite carers or foster carers (if appropriate).
Devora, I am sending flowers because I want more tears! (Disappoint me!) 
Hugs to all the amazing parents here.
