Research shows that most tormentors are taught their behavior by others.
If you've made the painful discovery that your child's aggression is a pattern learned firsthand from your husband, an older sibling, a grandparent or another relative, take action. Sometimes, however, well-meaning adults or older siblings are unaware of their aggressive actions. Avoid blasting the aggressor with accusations or blame, which can escalate tension at home. Don't ignore it or gloss over it. Then seek professional help.
