parenting decisions.

Video Games. I like them. I wonder if I should like them less. It isn't so much that I like playing them, I like the fact that they can occupy a child for any given amount of time. In fact, I often find myself wishing that all of my children liked them as much as Justin did and they would want to sit for hours in front of it just hanging out and giving me some quiet. I can't believe I am admitting this. But sadly its true. Justin would play for as long as I would let him, and some days I know he plays for an hour, maybe 2. Granted the games are all appropriate. Only e games are allowed. Justin is mainly into sports games (surprise). In my head I tell myself to limit his time. Then the other part of me says, he is a straight A student, he reads for a minimum of 45 minutes a day, he does his chores when asked, and if given the option of going outside or playing with someone he will usually turn off the PS3 and go to it. For example, today he spent one hour playing basketball with his brother inside and then another 45 minutes shooting baskets outside. So I tell myself its okay. I am wondering what to do about this during summer when he definitely will have more time to spend playing. perhaps a time limit will have to be put in place. hmmmm all these parenting decisions. I feel like parenting is somewhat like performing a science experiment - you try this and try that and take away this and you just hope it turns out right. For the time being, I think he's okay and I'll just let it be. Am I alone in this? Am I ruining my child?
