Monitor video game play the same way you need to monitor television and other media.
Be a loving, attentive parent who disciplines your child well. An aggressive child is more a product of dysfunctional parenting than anything else, including violent games and TV. According to Los Angeles-based psychotherapist Robert Butterworth, PhD, dysfunctional parenting, children with little guilt, and accessibility to firearms with little parental supervision can create violent children. “Most children who commit violent crime show an early combination of personality and family factors that include having trouble getting along with playmates in preschool,” Butterworth says. “By second or third grade they’re doing poorly in school, and have few friends. By the age of 10 they’re picking fights and getting labeled by their peers as social outcasts.” What’s more “they typically come from families where parents are poor at disciplining because they are indifferent, neglectful, too coercive or they use harsh physical punishment with little love.
