I and my son play all sorts of games on Xbox as our bonding time. He usually doesn't play Xbox without me. But I noticed two to three weeks ago, he started playing Xbox more than usual. He doesn't even ask me if I want to play with him. I'm not sure what has changed. All I can say is that I'm worried that he's getting too addicted to playing. Sometimes, he even sneaks out on me just to play. Should I be alarmed?
