Is this not the most ridiculous parenting ever???

I'm sorry but anyone that thinks social services is going to do anything because a 3 year old is swearing and playing GTA I don't think has the idea of Social Services and what they'll do as I do. I don't think they'll do anything, or is anything they can do, unless the kid has bruises, lives in a feces infected house, or at least shows some signs of serious neglect or abuse.

I think your post is just looking for ideas on what you can do to help this little kid that's turning into something else as you watch him grow up. I don't know what you can do though. You care about the little kid alot, so tell that to the mom, tell that to your brother, maybe tell them that "Gees, he's turning into a little monster since he started playing XXX, I don't know if I'd let my kid play that." Or say to your brother, "Hey man, quit swearing so much in front of your kid, he's beginning to sound like a little sailor." Maybe try saying something in a light mannered way and it might trigger a light mannered response where then you can maybe suggest ideas for changes if they seem like they will listen without taking offense. Good luck, but tread lightly.
