2m2r... There are three common causes of the behaviors the original poster talks about. These are Reactive Attachment Disorder (RAD), Fetal Alcohol Syndrome (FAS)/Fetal Alcohol Effects (FAE), and... yes, DNA. There are other less common causes also.
We didn't know if this child was adopted or not. OP has confirmed the child was not. I should have asked that first, though, because both Reactive Attachment Disorder (RAD) and Fetal Alcohol Syndrome (FAS)/Fetal Alcohol Effects (FAE) are more often associated with adopted kids.
