Of course - I can also tell you some stories that were less successful.
There is more and more research available every day related to adoption, issues kids who were adopted face, etc., that you can use to help you come to the best outcomes available. But I think you have to go into it knowing that if a child is adopted, they are coming from a traumatic background. Whether they remember the details or not, there's some trauma involved in "losing" their family of origin. If you ignore that, then you're setting yourself up for more struggles.
