Bullying Among Siblings — Not as Harmless as We Think

By ABC News | ABC News Blogs – 3 hours ago

“Mom, he’s picking on me!” With summer here and family road trips underway, it’s a phrase that parents may be hearing more and more from the back seat. More often than not, parents dismiss this kind of sibling bullying as harmless. Recent research begs to differ...

“There has been a lot of work to prevent or stop aggression for peers, but not much is seen for sibling aggression.”
Dr. Robin Mallett, a child and adolescent psychiatrist of the University of Texas Medical Branch in Galveston, believes this study “shines light on a type of maltreatment that many believe to be a benign part of growing up.”

I think that some of the comments are actually more enlightening than the article. Some of the comments make it very clear that there's teasing--and then there's abuse. And all too often, parents excuse or overlook a child abusing a sibling, whereas if some other kid did it, the parents would think s/he needed to be in reform school, or whatever they call it now.
