>>> medical round up. sibling rivalry and daddy brain. nancy snyder is nbc's chief medical editor. get right to it. new study released overnight on sibling aggression.
>> 32% of children said they were bullied by one of their own siblings so when we talk about bullying, what kinds of behavior are we talking about here?
>> this is a landmark study, it's verbal, physical abuse or taunting. it's also destruction of property. a sibling stealing stuff or wrecking it. over 3500 kids, this is in the journal of pediatrics and it shows while you and i talking about peer bullying, especially in the school setting, family bullying, sibling to sibling can have the same fall out.
>> a lot of kids bullied by a sibling are also bullied by peers in school but what stuck out to me in the study is even if they are only bullied at home it can have the same kind of devastating effect emotionally.
>> it can even be mild. so, a sibling stealing stuff out of your room, wrecking it, taunting you and they followed kids from 11 months all the way up to 17 and they found that whether mild or severe, the fall out of anxiety, depression, feeling more vulnerable in school, that mattered. so i would say the parents, if you wouldn't take certain behavior from a neighbor you don't take it from one sibling to another.
>> i have three kids and sometimes it drives you crazy to see how they treat each other. rarely physical in my house but it does get emotional and this say great warning to say enough is enough.
>> it's a good story.
>> thank you very much.
