Aggression in school-age children may be triggered when kids are 3 years old and younger and witness violence between their mothers and their partners. These kids tend to be more aggressive than other children their age.
Social worker Megan Holmes thinks it’s more a case of experience. She says, “People may think children that young are passive and unaware, but they pay attention to what’s happening around them." According the National Center for Children Exposed to Violence, between 3 and 10 million children witness some form of domestic violence every year.
