What's a typical age for kids to start? My son is 11 and is about 6 months into the process or so... And I'm also wondering if this can at all explain his mood swings? He can be the most loving kid in the world when he wants something, but if I ask him to get off of the computer you would think I severed a finger from his body!

We've had a few little discussions about "things" but he's a little shy like his Daddy and doesn't ask much, just listens for now. And hell, I'm an idiot, so I don't know if the things I tell him are correct or not!

Anything special I should be concerned about in this stage?
