There's no way in hell my darling 12 year old will be given a webcam. She certainly isn't allowed to have a computer in her room. At no point in time will she be a member of YouTube, and if I catch her abusing the privilege of wearing makeup, I'll take it away.
The worldly attitude the girl in the video presents saddens me more than anything, because it's a sign of lazy parenting.
