I agree...but keep in mind that there are plenty of "normal" kids that have things happen to them at early ages that may impact them socially later in life.
I guess I just don't like the idea that some people automatically assume that because the kid is adopted, that must be the cause of his issues. I'm not saying that all the people here have assumed that, but my experiences have shown me that there are a lot of people in the general population that do place a stigma on adopted kids.
The fact is that you can never know if a problem is adoption-related per se, or just the way the child was wired to start with, a problem with the adoptive home environment, pre-natal care, etc. The list goes on and on.
But it's also a fact that internationally adopted children experience many problems at significantly higher numbers than non-adopted children. To me, that just means adoptive parents need to be more vigilant in addressing problems as early as they can, instead of letting people convince them to let things go because "so and so down the street had the same problem, and they never got help but they're fine now". I only wish I had realized that earlier - I unfortunately fell for that line a few times, and have had to pay the price. Or rather, my daughter has had to pay the price.
I would also like to point out to everyone that being internationally adopted, while sharing many experiences and emotions with domestic adoptees adopted close to birth, also brings along with it a very different set of issues that are unique to international adoptees. These children are often a bit older at adoption, have lived in institutional enviroments, have had to switch languages at critical times in development, have completely unknown family history, and their mothers often had extremely poor pre-natal care (if any) and nutrition, and often have drank/smoked/etc during the pregnancy. And that's the short list. Again, for those reasons, problems need to be dealt with more quickly. If you don't, the problem is likely to grow and become much more difficult to deal with, not just disappear. It's not a "stigma", just a reality of the situation.
If this parent is to the point of crying to a friend with frustration over the issue, then there is a problem that they need help with. Because the child is adopted, the adoption agency and social worker should be contacted to see if they can provide any help, along with the pediatrician, school system, etc. Adoption agencies and social workers are charged with helping with many post-placement problems, regardless of whether they are adoption related or not so the parent should use that resource.
