Parents can have difficulty in providing a 'normal' home for any other children. Siblings classically respond in one of two ways. The first is to indulge in anti-social behaviour because they observe that this is the way to gain their parents' attention. This can include younger siblings becoming involved with the same perpetrators. The second is to become the 'good' child as they see the devastation that their sibling is causing. This is usually accompanied by extreme resentment (often extending into adulthood) because they think that their good behaviour was hardly noticed.
