my DS is now 7 years old...going on 15! Has developed this appalling attitude that I didnt expect to see until he was at least a teenager. Talks like a HOMEBOY (though not black), acts like a tough streetwise guy, and uses the most awful language. Keeps saying yeah, yeah, whatever and gives me so much cheek I am gobsmaxcked. I would not have dared to speak to my parents like that as a teenager...but he is only 7. What can I do?
