My DS is nearly 13 and all he wants in the world is a PS3. He has saved up for it so could buy one himself, or we could contribute as birthday present but I really really don't want him to get one. He is eldest of three by 10 years, so almost like only child and worry it will just isolate him, sitting in his room playing it, as its not practical to play in our living room with babies etc. I just don't know if I am being unreasonable. Does anyone's DC have one at 12/13yrs? How do you monitor play? Am I being unreasonable to say he can't have it, I just feel like I may have lost touch with reality and don't know how to parent a teenager.
