In spite of an increased awareness of the problem, large numbers of children still suffer abuse at the hands of their parents or guardians each year. Although many parents are likely to become frustrated and angry with their children from time to time, most are able to cope with their anger and frustration without resorting to violence. However, some parents appear to lack the skills necessary for handling their anger constructively, and when their emotions become overwhelming, they may abuse their children physically, emotionally, or sexually. In many cases, abusive parents were themselves victims of child abuse, and as adults they revert to the patterns of abuse they encountered in their families. Although child abuse occurs in families of all races, religions, social circles, and economic classes, many abusive parents are emotionally isolated, and have a skewed perception about what constitutes realistic child behavior. Alcohol and drug abuse can also be major factors in child abuse. Since child abuse can have a profound psychological and emotional impact on the victims, it's important to report suspected cases to the proper authorities so the child can be removed from the dangerous environment and can receive the counseling necessary for recovery. The person reporting the abuse is usually allowed to remain anonymous. There are a number of resources for parents who find themselves increasingly frustrated with their children, including counseling, parenting classes, and self-help groups such as Parents Anonymous.
