So how often does your kid sit down with his PS3? Xbox? Among the first signs it may be too much are...  falling grades and antisocial behavior.  Pediatric psychologist Michael Manos at the Cleveland Clinic Children's Hospital says pathological gamers become absorbed by the experience, spending from four to six hours a day playing. According to Dr. Manos, they will disengage from the world around them and often have trouble relating to their parents. He describes the problem as being similar to other forms of addiction. Dr. Manos recommends that parents reach an agreement with the child ahead of time that limits how long they can play video games.
