You need to look up reactive attachment disorder. And then read up on it. While your child may or may not fit this diagnosis, it will give you information on attachment issues which is what it appears your child is experiencing. I would also recommend that you find a support group in your area for adoptive parents. There are a lot of adoptive children with attachment issues and not only ones from other countries. So don't feel like you are alone if you can't find parents who have adopted from other countries. You need to make sure you are getting the support that you need. Otherwise you will burn out. In addition to psychotherapy I would recommend that you check out occupational therapy to help with attachment. Good luck.
