Ah, my son is 14 now.
"Santa" gave him his first game boy when he was 7, and boy, does she regret it now!!! His MawMaw and Father have added to the mix, with the result now being a PS3. Is he addicted to electronics? I would have to say "YES!". Do I limit his gaming time? "YES", it is only to be played after homework and chores, and many weeks not at all Mondays-Thursdays. Weekend play time is after chores, and whatever else I decide, are completed. I do let him stay up and play on Friday nights as everyone needs at least one night a week to fully relax and play.
My son does go on about his games. And on, and on, and on....he wants to share his fun with me - and since I don't play his games - I am horrible at them to the point of hilarity - I tune in enough to smile, and say "really,l how neat" at appropriate times.
Since the gaming systems are all in the family room, I see and hear more of the game play then I would like - but it keeps him "honest" and his on-line friends all know that I am in the room, so it cuts down on some of the trash talk that teen boys seem to be prone to.
But, I make sure that we do other things together - board and card games, playing chase in the house, local events, festivals and markets. I talk to him about current events and local politics, and anything that comes to mind. All ways to build him into a well rounded adult. Albiet, one who loves video games. LOL
It is all about moderation. Let's face it, our kids have toys that did not exist when we were kids (especially for me at 46!!). I pay enough attention to know what he is doing and who he is doing it with, since he is on-line now, but I give him some freedom about it all also. I do limit his game time, and I do take away his game time as a consequence for poor behavior.
So, go ahead and sit down and let your son tell you all about his games - look over his shoulder once in awhile so you are familiar with it. Then tune out and think about sandy beaches and drinks with umbrellas in them and occasionally smile and mutter "Oh, wow, really?". Then break out the Monopoly board or go outside and throw a ball around. Just have fun!!!
Good Luck and God Bless
