Even in the very best families, the most average of circumstances, all people have issues of some sort. And so when asked if adopted kids will “have issues” one must answer – “most assuredly!” All kids and all adults grow up with specific problems to deal with, just by way of mortality.
Adopted children may have issues that have began with what happened before adoption in their lives. There may be abandonment or attachment issues, but even those who are not adopted may have the same problems. The real answer is to love your children – adopted or biological. When that happens, all issues can be worked through!
