I think for anyone considering adoption, heavily research attachment disorders. And I mean, HEAVILY.
It's pretty much a given that a child entering a new family WILL have attachment issues. How could they not? The difference is, will it be an Interrupted Attachment Disorder, which can heal, given time and proper exercises/work done (sometimes it manages w/out any focused effort, but why not do attachment exercises regardless, kwim?) or Reactive Attachment Disorder (RAD) that rarely, if ever, fully heals?
Personally, I think *every* potential adoptive parent should look long and hard into RAD. Could they handle that? Are there resources in the area? RAD specialists, from what I understand, are few and far between. Kind of a, 'hope for the best, prepare for the worst' scenario.
Unfortunately, the 'love heals all wounds' is a steaming pile of bull doody in too many situations in today's world. RAD is absolutely one of those situations.
