This is so sad. I work with second graders. We had one 7-8 year old this past year that had a lot of issues. She was fine, when medicated. Without medication, she was dangerous. I can see a child like that hurting a baby. Our student would tell me that she couldn't control herself. She knew she was going to do something bad. I imagine this girl was a lot like that.
I have a friend that is raising her grand-daughter. The child has many issues and must take medication. She can attend school, but there are guidelines. This child also has "anger-mgmt" issues. The child has attended therapy sessions for the past couple of years.
My friend is quite concerned about what will happen to this child as she ages. So far they have not been able to reduce the medication levels and have not really made any real progress in modifying the child's behavior. My friend thinks at some point this little girl will end up in an institution because she will not be able to care for or control the girl. It is a very sad situation. And yes, the young girl's problems stem from abuse of her parents.
Very sad,
Salem
